“Bigger than government”: exploring the social construction and contestation of net­zero industrial megaprojects in England

hydrogen production infrastructure, and HyNet seeking billions in investment to build green and blue hydrogen facilities along with a carbon storage network near Manchester and Liverpool. We draw from the social construction of technology (SCOT) literature to examine the relevant social groups, interpretive flexibility, and patterns of closure associated with Zero Carbon Humber and HyNet. We connect our findings to eight interpretive frames surrounding the collective projects, and make connections to problems, contestation, and closure.


Introduction
Low-carbon and net-zero industry is of paramount global importance. According to the International Energy Agency (2022), the industrial sector accounted for 38 % of total final energy use in 2020. The most recent report from the Intergovernmental Panel on Climate Change also calculated that industry represents the quickest expanding sector of carbon dioxide emissions, as well as the single largest source of global greenhouse emissions (more than one-third) when one accounts for related electricity consumption and heat generation (IPCC, 2022).
Nevertheless, industry is frequently framed as hard-to-decarbonize given its diversity of requirements, technologies, and supply chains, many of which are unique to particular sectors. For instance, the food and beverages industry utilizes large amounts of low-temperature heat and refrigeration, but must offer an extremely large diversity of food and drink products while also maintaining special considerations about health, safety and waste (Sovacool et al., 2021). Glass, by contrast, uses high temperature heating and blast furnaces which account for 75-85 % of total energy requirements (Furszyfer Del Rio et al., 2022). Petroleum is used not only for crude oil production but also about 90 % of pharmaceutical, agricultural chemicals, petrochemicals and plastics production, each with their own distinct supply chains in need of decarbonization (Griffiths et al., 2022). The iron and steel industry is the largest user of coal and the most greenhouse gas intensive in terms of emissions per weight of product (Kim et al. 2022).
Net zero commitments since 2019 have begun to challenge the carbon intensity of these various industries, leading to increasing policy interest in industrial decarbonization in recent years (International Energy Agency, 2021). Nevertheless, progress on decarbonizing industry has been phlegmatic (International Energy Agency, 2022). In spite of its critical importance to global climate stability, industry has long been sheltered for the past decade from strong energy and climate policies over concerns about job losses, national competitiveness, and carbon leakage.
Against this backdrop, the United Kingdom has emerged as perhaps an unexpected leader in industrial decarbonization efforts. The United Kingdom is actively pursuing low-carbon industry by 2035 and net-zero industry as soon as 2040 (Devine-Wright, 2022), supported both by law (the 2019 Amendment to the Climate Change Act of 2008) and the newly launched Industrial Strategy Challenge Fund. The Fund includes £170 million for Clean Growth and Transforming Construction, matched by £250 million of private sector investment (UKRI, 2022). The approach taken to net zero industry in the United Kingdom is based on clusters, which cut across engineering, spatial, and socio-political dimensions. For example, in the UK, six specific clusters account for more than 50 % of direct carbon emissions from industry (HM Government, 2021). Although emissions numbers are contested, using official government data two of the largest of these clusters in England in terms of industrial emissions are the Humber (10.03 million tons of carbon dioxide equivalent per year) and Merseyside (5.04 million tons of carbon dioxide equivalent) (Sovacool et al., 2022). Such estimations could reach as high as 36 million tons of carbon dioxide equivalent for places such as the Humber if energy production and bio-derived carbon dioxide processes are added to the tally.
In this paper, drawn from a rich mixed methods original dataset involving interviews, site visits, and a review of the literature, we explore ongoing efforts to decarbonize both the Humber and Merseyside through the lens of megaprojects. Net-zero cluster plans in the United Kingdom have several challenging characteristics of "megaprojects" because they have a high degree of technological novelty, structural complexity, systems integration, and accelerated deployment to meet government targets and final investment decisions by 2025 and 2030 (Geraldi et al., 2011;Flyvbjerg, 2014;Sovacool et al., 2022). Megaprojects in both the Humber and Merseyside extend well beyond each cluster, making them spatially expansive. Both also have aggressive implementation plans in place for the deployment of net-zero infrastructure, making them technically complex. Zero Carbon Humber will require tens of billions in investment to build and operate the country's first large-scale bioenergy with carbon capture and storage plant alongside carbon and hydrogen networks, and HyNet may necessitate tens of billions of investment as well to build green and blue hydrogen facilities along with a carbon storage network near Manchester and Liverpool and North Wales. These two clusters are leading national netzero ambitions, with actual, enforceable timetables to achieve decarbonization.
In this paper, we draw from the social construction of technology (SCOT) literature to examine the relevant social groups, interpretive flexibility, and patterns of closure associated with Zero Carbon Humber and HyNet. We connect our findings to eight interpretive frames surrounding the collective projects, and make connections to scale, contestation, and temporality. In doing so, we make contributions to the application of SCOT to megaprojects and particular problems, functions, and risks therein (as opposed to earlier work focusing on individual products, such as Bijker (1997)); by emphasizing the spatial and reversible nature of closure; and by highlighting some of the international elements of technology transfer, which have been previously treated only as a part of the environment (Oti-Sarpong and Leiringer, 2021) in such science and technology studies scholarship.

Research design and conceptual approach
In this section, we briefly introduce readers to, and justify our selection of, Zero Carbon Humber and HyNet as case studies, explain our mixed methods research design, and summarize our conceptual approach of the Social Construction of Technology (SCOT).

Case study selection
We began by selecting two confined industrial clusters to examine in more detail in the United Kingdom. We selected the Humber because it is the largest industrial region in the country, home to £52 billion in gross value-added economic activity along with 600,000 jobs (Drax, 2019). The Humber region spans more than 100 km from Bradford to the mouth of the Humber Estuary, and it includes a robust mix of different industrial emission sources including Scunthorpe (home to the largest steel plant in the country) along with the largest biomass power Table 1 An overview of the Zero Carbon Humber and HyNet North West decarbonization megaprojects.  (Drax), a large chemicals park (Saltend), and two refineries. They have a long history of supporting innovative energy technologies and decarbonization, with the White Rose carbon capture and storage project proposed more than a decade ago (Ecofys, 2017). Within the Humber, although there are other projects (such as Humber Zero or V-Net-Zero), Zero Carbon Humber is the largest, and most ambitious. The Top Panel of Fig. 1 visualizes Zero Carbon Humber's emphasis on multiple locations and technologies for net-zero. Merseyside, by contrast, is smaller than the Humber but it also has a diversity of industrial centers of activity including chemicals, food and beverages, fertilizers, glass, oil refining, and many other hightemperature operations (Ecofys, 2017). The HyNet North West project (also shown in Table 1 and visualized in the bottom panel of Fig. 1) seeks to utilize carbon capture and storage, hydrogen, and fuel switching to decarbonize the area. The plan also includes blending hydrogen with natural gas for supply to homes and for transport (e.g., heavy goods vehicles and trains). Various, smaller projects also sit within HyNet: the HyNet Industrial Fuel Switching Program, HyNet Hydrogen Supply, HyDeploy, HyMotion and H2GV (for vehicles).

Mixed methods research design
With our two regions and megaprojects selected, we embarked on a research design involving original data collection via interviews and multiple site visits, analysis of externally oriented presentations and reports, internal planning documents, trade journals and other sectorspecific publications. Interviews were conducted with 46 expert respondents over the course of February to June 2022 (see Table 2). We intentionally sought to include a diverse range of perspectives from industry (who dominate our sample, given the topic) but also national government and policymakers, local authorities, and members of academia. Within industry, we were able to secure interviews with some of the most prominent actors in each industrial megaproject, including all lead institutions.
Annex I shows our interview guide and list of questions asked across the interviews, with some interviews focusing on context and high level policy issues, and others more narrowly focused on specific project management relating to each industrial cluster. Questions generally focused on the history and drivers behind each project, expected benefits and prospective barriers, as well as implications for policy and lessons learned. Interviews lasted between 30 and 120 min, were recorded, and then fully transcribed. They were then coded by the authors inductively to identify recurring themes and topics. Our interviews were semistructured, enabling the research team to gauge different topics that emerged in more flexibility and depth. To protect the anonymity of respondents, all specific qualitative data are referred to only by a generic respondent number. Ethics approval for the project was granted by the Social Sciences & Arts C-REC board at the University of Sussex with reference number ER/BS289/6.
To complement the interviews, and match stated preferences with a type of revealed or observed preferences (to improve triangulation), members of the research team also conducted a total of 20 site visits (See Fig. 2). This involved seven site visits across the Humber (with accompanying visits of the cities and villages of Easington, Hull, Immingham, and Drax):  The site visits enabled naturalistic observation as well as the documentation of visual evidence (photographs) about operations and onsite industrial practices. In some cases they also led to further research interviews.

Conceptual approach of the social construction of technology (SCOT)
To assess emerging decarbonization megaprojects in England, we adduce literature arising from science and technology studies and the history of technology (Pinch and Bijker, 1984;Bijker, 1997;Hughes, 1986;Klein and Kleinman, 2002;Bijker, 2008;Pinch, 2009;Oti-Sarpong and Leiringer, 2021). These collective works posit that the evolutionary pathway of a new technology (such as reconfigurations of industry, hydrogen, or carbon capture) is not only a function of its technical qualities and characteristics, but equally so of its integration or social shaping with society. One approach known as the "social construction of technology," or SCOT, articulates that technology and society are mutually constructed together (Bijker, 1993). Within this framework, four important concepts have been deployed: relevant social group, interpretive flexibility, technological frame, and closure and stabilization.
Relevant social group describes the varying institutions and organizations that share the same set of meanings attached to a particular technology, project or sociotechnical system. Such social groups play a core role in shaping and defining the problems that arise during the development of new systems; they can both give meaning to technology, and define the problems facing that technology (Pinch, 1996). As Bijker (1993: 119) once wrote, technology "does not suddenly leap into existence as the result of a momentous act by a heroic inventor; rather, it is gradually constructed or deconstructed in the social interactions of relevant social groups".
Connected to such groups is the concept of interpretive flexibility. This idea implies that relevant social groups will possess different ideas about what a given technology does. In simple terms, different groups envision particular technologies in disparate ways. New technology becomes "heterogeneous" because its meaning for stakeholders, rather than being fixed, is actively interpreted and thus negotiated by the social groups connected to it (Sovacool, 2011;Noel and Sovacool, 2016). Pinch and Bijker (1984) distinguish two types of interpretive flexibility: first, in how different social groups conceive of technology; second, that there is no one possible way that technologies are designed. Klein and Kleinman (2002: 3) define interpretive flexibility by noting that "technology design is an open process that can produce different outcomes depending on the social circumstances of development" and by concluding that new technologies are always the product of inter-group negotiation.
A technological frame or interpretive frame refers to a "frame" that captures the interactions that occur between the relevant social groups and their negotiated interpretive flexibility about a technology. A frame in this context is defined as "all elements that influence the interactions within relevant social groups and lead to the attribution of meanings to technical artifactsand thus to constituting technology" (Bijker, 1997: 123). Klein and Kleinman (2002: 31) suggest that such a frame can include elements as disparate as goals, theories, tactic knowledge, testing procedures, problems and their solutions that all structure how a group thinks about a particular technology. Bijker (1997) argues that interpretive frames have at least two additional features: heterogeneity (frames will vary based on actor and perceptions of interpretive flexibility) and fluidity (frames will change over time and can become built up but also broken down). Technological frames can even become absorbed by national institutions or policies, with policymakers themselves subscribing to frames about a given technology in ways that advance their status or align with the interests of their constituents (Kingdon, 1984). Frames can also become connected to particular problems a technology can solve (Oti-Sarpong and Leiringer, 2021), as well as the particular value propositions that the technology offers in addressing those problems (Mulholland et al., 2019;Mulholland et al., 2020).
These pressures arising from competing frames result in technology being simultaneously malleable and contested, leading to a final concept from SCOT: closure. Closure or stabilization occurs when a consensus emerges that problems arising in the development of technology have been alleviated, and/or an agreement emerges concerning a dominant frame among relevant social groups. These problems need not to have been solved in the common sense of the word, but only that the relevant social groups have perceived those problems as solved. Misa (1992: 110) defines closure as "the process by which facts or artifacts in a provisional state characterized by controversy are molded into a stable state characterized by consensus". In their examination of scientific controversies, Engelhardt and Caplan (1987) and Beder (1991) identified five different types of closure. Closure can occur through: • Loss of interest, where a controversy ends because relevant social groups lose interest; • Force, where disagreement ends when an external authority declares and imposes a decision, or by the use of state power, or even by loss of financial support; • Sound argument, where relevant social groups freely concur that a particular solution is the most appropriate after deliberation and democratic debate; • Negotiation, where relevant social groups reach a compromise; • Consensus, where the force of one position has overwhelmed all others. Beder (1991) suggests that two forms of closure-negotiation and consensus-particularly depend on social dynamics and the interaction of relevant social groups. Also, while the term rhetorical closure implies a degree of stability, it is not always permanent: controversies and conflicts can reemerge and new challenges can arise.
Generally, the literature from SCOT suggests that frames and closure (or lack thereof) can exist in three configurations. In some instances, no frame may be present, as in the early history of the bicycle when no single dominant group had a set of vested interests in the success of the technology. Here, success depended on the formation of a constituency, and the technology is open-ended. In others, one frame may be present because a dominant group is able to insist upon its definition of the problems and solutions. This would be when closure is reached. A third configuration relates to when multiple frames are contested, and criteria external to such frames are needed to resolve differences. As we will see, this is the case for both of our industrial decarbonization megaprojects.

Limitations
Some caveats and limitations deserve to be mentioned concerning our approach. In combing through our interview data, more than eight frames were present. The authors present only four frames per each project (two positive, two negative) both for symmetry, and to keep the article fairly short. Nevertheless, the frames we present are illustrative and not meant to be exhaustive or fully representative. In some cases, frames are very close to themes or dimensions of each project. In other words, we take a looser and broader conception of relevant social group and frames, one that includes actors shaping design choices (such as engineers and funders) but also those in the broader environment such as civil society groups and academics. This is similar to the application of SCOT and frames in Sovacool (2011) and Goldthau and Sovacool (2016). Given the embeddedness of the projects into the sociotechnical fabric, frames can refer to both, components of the project (e.g., a gas compressor station, a pipeline, a disrupted bike path) and systems-level impacts (e.g., jobs, effects on trade, the shaping of international prestige, etc.). Frames also cut across descriptive and normative elements of the two projects: some frames may relate to what the project is, but others could relate to what it does, and still others to what it represents or symbolizes. To be clear, some of the frames such as a "complex machine," "leveling up of deprived areas," "stepping stone for hydrogen," and "an environmental boondoggle" were evident in both projects; but to illustrate a variety of frames, we mention them only once (i.e., related to one project) rather than twice. Moreover, some frames are evident historically, i.e. they refer to things already occurring, such as infrastructure being built or jobs being gained, whereas others are more speculative, and relate to potential social acceptance or environmental problems. The bulk of our frames, as we will note in Section 4, are positive rather than negative, but this could relate to a strong majority of our respondents being from industry, rather than other sectors such as academia, government, or civil society.

Results: elucidating eight sociotechnical frames
This section showcases our results, arranged inductively around four prominent themes found within our data for each project. These cut across technical, economic, political, and socioenvironmental dimensions. After presenting our results, Section 4 further analyzes them according to the themes of problems, functions, and risks; consensus, contestation and tradeoffs; and closure and stabilization.

Four sociotechnical frames for Zero Carbon Humber
Four illustrative frames are evident concerning Zero Carbon Humber: two positive ones of a complex and even innovative technology and a mechanism for economic leveling up, and two negative ones concerning the political embedding of fossil fuels and deleterious social and environmental impacts.

Technical: a complex, layered machine
This particular frame focuses on the technical and engineering aspects of Zero Carbon Humber. The frame emphasizes Zero Carbon Humber as a very complex machine, one with layers of coupled technologies and systems at work. R14 depicted this frame well when they noted that: Zero Carbon Humber is not one technical system, but many, and it will involve distinct elements such as gas wells and optimized injection systems, carbon reservoirs, the provision of cushion gas, hydrogen generation, polishing facilities and even international pipelines, it's a lot bigger than the Rough gas field, it's even bigger than government.
R03 elaborated on this technical frame as well, noting that Zero Carbon Humber is intrinsically integrated with the East Coast Cluster and Northern Endurance project. That is, Zero Carbon Humber is interconnected with other regional decarbonization efforts and projects such as the East Coast Cluster (near Teeside) and Humber Zero (a competing project on the other side of the Humber estuary). As R03 This frame thus envisions Zero Carbon Humber as a complex megaproject sitting within and connected to even more complex and layered conglomeration.
R13 spoke about how the combination and interlinkage of such projects would only further benefit the Humber and accelerate decarbonization. As they said: We have an embarrassment of riches I like to say in the Humber. We are the only cluster, the only industrial cluster that has got two onshore deployment projects and we are quite possibly also likely to have two offshore deployment projects. We've got Zero Carbon Humber, which is linked through the Northern Endurance Partnership to Teesside, and all of that is styled as the East Coast Cluster. Then we've got Humber Zero. Humber Zero can play as it were, connect into the East Coast Cluster, but they are also evaluating the opportunities to connect into Harbour Energy, the V Net Zero deployment project, an offshore deployment project that will route CO2 out south through Lincolnshire to the Viking and Victor Fields. You've potentially got CO2 going out from the north half of the Humber towards Endurance, or you have got CO2 going out south half of the Humber as it were towards the fields off the Lincolnshire coast … it's like a series of Russian dolls, they are all linked.
These particular statements not only reveal the financial capital intensity of such a complex machine, but also its spatial expansiveness (covering multiple local authorities and Local Enterprise Partnerships) and even a new form of technical organization termed "whole place decarbonization" and how it is building a superstructure akin to "Russian dolls" that are closely linked together.

Economic: leveling up of deprived areas
This second frame, by contrast, focuses on the economic fruits to be harvested from Zero Carbon Humber, most likely in the forms of future jobs, enhanced skills, and a leveling up of deprived, peripheral areas like Hull. R38 explained this potential as follows: There are big opportunities for the Humber to grow economically from the project. We've got two of the UK's six oil refineries within the Humber area. We've got the Equinor storage hydrogen plant as well. The jobs or new industries that could develop on the back of the CCS bit, are very important to us at the moment. It's inevitable that people, because it's such a huge opportunity and such a new industry, will want to come and work. I think that's great. You know, bringing new skills and fresh people into the economy is great because it just adds to the mix of people within here. We've only got one university, which is obviously the University of Hull, but there is a great opportunity for graduate retention as well. So people that have come to Hull, got qualified but aren't from Hull, and then  Sovacool et al. they'd stay in Hull or stay in the Humber. So we keep that knowledge within the city, as well as attracting new knowledge into the wider Humber area. We want to use the opportunity of cluster decarbonization to strengthen the local economy and provide opportunities for local people as much as we can, and give a reason to stay within the city and within the Humber, and be able to have careers here without having to move away.
Their statement emphasizes not only direct economic benefits such as jobs, but indirect ones such as strengthening the local university, attracting new people to the region, as well as retaining people that come to the region but may have left otherwise. R38 later remarked that such investment would also help reduce regional vulnerability, because "all of our main industrial bodies are all in the most vulnerable part of the country, for a whole variety of reasons." As further evidence of this frame, the city of Hull has even run a campaign with regional partners called "Oh Yes! Net Zero" to increase public knowledge about net-zero, and also inform and educate them about skills and educational opportunities via exhibitions, advertisements, and community training programs. "Oh Yes! Net Zero" was launched in March 2022 with a keynote speech from dignitaries including the former State Secretary for Energy (and Business) Alok Sharma, who was also President of COP26. As Mr. Sharma stated, "Cities like Hull [in the Humber] are leading the way with 2030 carbon neutral targets … collaboration is creating a clean industrial cluster, as a city, a hub, of offshore wind; helping with the energy transition (University of Hull, 2022). Fig. 3 shows two of the public messages being circulated from the campaign near Hull City Centre.

Political: troublesome way of repurposing incumbent legacies
This frame is more critical of Zero Carbon Humber, and it suggests that rather than helping advance progressive and meaningful decarbonization, it is instead a problematic way of merely repurposing and extending fossil fuel infrastructure, especially natural gas, which would be utilized for blue hydrogen. R03 indirectly affirmed this frame when they stated that: Equinor has got some really big ambitions on being seen to decarbonize their operations, and the way Equinor view it they can't continue to sell natural gas without providing the political space for customers to decarbonize that natural gas.
R05 also questioned the utility of pursuing natural gas based decarbonization projects because they rely so heavily on carbon capture and unproven technology. This also makes it prone to cost overruns and delays: The government should be rigorously questioning and opposing long-lived investments that justify continued fossil fuel use, not investing in them. It is unsafe and even unethical to rely on unproven technical fixes like carbon capture, or reward corrupt incumbent firms, their lobbies, and their bureaucrats. It is a political gesture to reward fossil fuel companies, nothing more.
R18 spoke about how such decarbonization projects cleverly normalize fossil fuel use and carbon capture. As they elaborated: The beauty of blue hydrogen is that it enables a gas economy like the UK, with its strong oil and gas industry, to extract hydrocarbons and produce fossil fuels for another 5-10 years. It's a really smart move, to make the public think that the political leaders are smart, they are taking charge, they have this infrastructure, pipes and tubes and basins, all of these skills. What they are doing is making carbon capture and hydrogen seem normal, sensible, and the best way to solve a number of problems, even if they are behind those problems in the first place.
One strong driver behind this frame is the need to recover sunk costs and embedded investment already placed in long-lived assets for delivering fossil fuels to the UK. One such investment, owned by Equinor, is the £1.7 billion Langeled Project (BBC, 2006), which exports natural gas from Norway to the UK, where it could be used to make blue hydrogen. That pipeline alone is fairly new, commissioned in 2004, and required a substantial investment from Equinor and consortium partners including a marine pipeline, a pipeline landfall, and a new gas receiving facility shown in Fig. 4 (Statoil, 2004). The longer Equinor can utilize such assets, the more revenue and profit they can accrue; conversely, a premature retirement of the pipeline (if fossil fuel imports were reduced or phased out) would be what R18 called "a political nightmare for Norway and their industrial strategy."

Socioenvironmental: an impending social and environmental blight
This final frame is also critical of Zero Carbon Humber, and it depicts the project as a blight on the environment and a problem for local communities. Previous construction of parts of the infrastructure connected to the project, such as the Langeled gas pipeline or the Easington terminal, did have negative environmental impacts such as carbon emissions and air pollution caused during construction and operation; the release of exhaust gases such as sulfur dioxide and nitrogen oxide; the potential effects of hydrocarbon leakage and spills on marine life; and interference on navigation and fishing activity through the creation of an exclusion zone (Statoil, 2004). The proposed scheme to add BECCS capability to the Drax Power station in particular would necessitate building compression and treatment systems that would interfere with roads and farmland, and also interfere with community rights of way by disrupting more than 200 byways and footpaths shown in Fig. 5  Their statement underlies how the public could transition from being ambivalent about the project to hostile when they realize it will cost them more and interfere with their daily lives. R03 argued that public concerns could also become amplified over hydrogen production: You are right, of the concerns that we do hear one is around the credibility of blue hydrogen vs. green, is it really green; and another is around safety of CO2 transport and storage. So these are two kind of public concerns we need to become better at addressing.
R13's notion about the project being a political "hot potato" was further captured later in the same interview:

proposals have been put in just yet. There is quite a lot to do, so if you end up in some sort of Hinkley Point C-esque or Sizewell C-esque planning debacle deliberation that might go on and bounce from one traditional enquiry to another, all bets all of a sudden are off.
R17 concurred when they noted that such socioenvironmental issues could become staunch political obstacles: I don't see the political will, especially interstate political will, to make this a reality, to handle the social irritation it may cause. I don't see politicians with the political intelligence to make a multi-generational deal.

Four sociotechnical frames for HyNet North West
Similar to our Humber case, four frames were also evident by HyNet North West: two positive frames of a technical steppingstone to achieve a hydrogen economy and a political posterchild for how other regions can decarbonize, and two negative ones related to a gap in skills and training and possible harm to the environment.

Technical: steppingstone to a hydrogen economy
Similar to the Humber, HyNet has a positive technical frame, but one that envisions a more expansive connection to a hydrogen economy, including the enabling of other technical advances including hydrogen homes and automobiles, smart grids, and even coupling to nuclear power, tidal lagoons, and other forms of renewable energy. Project documents such as the Net Zero Northwest Cluster Plan (Net Zero North West, 2022) even visualized these elements as all sprouting from hydrogen manufacturing enabled by HyNet in Fig. 6. R19 captured this thinking succinctly when they spoke about how: HyNet, at the moment, is very much focused on delivering in this region but we are thinking bigger. We already have very vague but growing plans on a western mega cluster which looks up to Cumbria, across Lancashire, and even out to Ireland … Yes, yes, hydrogen out to Ireland, there're pipelines that run across. So we are thinking bigger, that is obviously further into the future. By expanding that network up and looking at alternative places to produce hydrogen, such as Cumbria, nuclear becomes more viable when you do that .. so do cutting edge renewables like deep offshore wind or tidal lagoons. R21 spoke about the great enthusiasm for hydrogen and HyNet within the region:

People are biting our hand off for hydrogen at the moment. (Laughter). If we could supply hydrogen now, people would take it. Five years ago, I was almost knocking on doors to get people to like hydrogen, it was quite a challenge. But now, the reality is different, these businesses don't have an alternative, many of them …
HyNet is an affirmation that we need hydrogen as much as we need renewables and nuclear for those, we need to be doing everything … So we've got several stages of build out of the pipeline infrastructure. Essar itself, at Stanlow, will be the first hydrogen user. It will decarbonize some of the processes on site. The refinery at Stanlow, itself, will be the first hydrogen user. There are two or three sites located very close to Stanlow that will be the next users. Then the network builds out. Cadent is currently in the planning consent process or the DCO process for what we call phase two of the network, which will connect… It's about 100 km of pipeline, that will connect about 10 industry and power users up. Then, beyond that, there's a phase 3 of the network, they'll be another 200 km of network that will go up into the southern part of Lancashire and then down into Teesside and right across to Liverpool. Then there are other assets further up, further north, on the west coast in terms of oil and gas assets in Morecambe Bay, for example, and Barrow area. We'd be silly if we weren't having conversations with the owners of those assets.
Such a statement exemplifies not only the spatial extensiveness of the ultimate hydrogen network and economy, covering multiple regions and metropolitan areas, but also a phased approach to implementing where things build "up and out." From there, R21 spoke about how hydrogen homes and hydrogen transport (especially trains and trucks) would naturally follow. Edwards et al. (2022) also illustrate how HyNet is being coupled and integrated with multiple other regional hydrogen projects including Project Vanguard (the first green hydrogen fueling station in the Northwest); Project Centurion (a 100 MW Power to Gas energy storage system); HySecure (a demonstration hydrogen salt storage project); HyDeploy (the piloting of homes using hydrogen-gas blends); and the Liverpool Hydrogen Bus Trial Project (which features 25 hydrogen buses).
Other respondents spoke about how specifically blue hydrogen, from natural gas, was a critical enabler and facilitator, a bridge, to green and low-carbon hydrogen that would come later. R16 even referred to this as the "utopian" scenario by declaring that:

The utopia for most stakeholders when you speak to them is green hydrogen and all hydrogen being green hydrogen, but that's not really economically viable at the moment. So we help them to understand that this is a transition. Exactly the same thing happens in the electricity distribution industry, where you needed to bring lots of renewables online. Lots of electricity was generated by coal initially, and what we've seen is a growth in renewables, and eventually, all the new renewables will disperse everything else on the system. So it's seeing blue hydrogen as a transition to green, but we need lots of hydrogen initially to start decarbonizing the industry, and the only way that you're going to make that happen in the next few years is with blue and these large industrial clusters producing hydrogen at volumes that then initially decarbonises industry, and then moves out to other areas in the surrounding region.
Once this occurs, with industry anchoring a hydrogen network, R16 agreed that hydrogen would expand further to be utilized in people's homes, for domestic and commercial heating, and for transport all across the North West and North Wales.

Political: a posterchild for decarbonization
Contrasting the technical frame, this frame focuses on the political dividends from HyNet, and how it could offer a much needed template for other regions of the UK, and even the world, intending to decarbonize. R17 spoke about how HyNet was being supported by a "superstrong political coalition": In order to build enough societal, economic, and political momentum and acceptance, there are canny political operators and economic operators who know that in order to get what they want, money out of treasury, or better policy settings, or subsidies, or tariffs, they must sing the tune that the piper calls. That current call is decarbonization. HyNet comes in and local authorities now have a whiz-bang shiny physical asset that people can look at. You will see local politicians standing in front of a collection of pipes, in a high-viz jacket and a hardhat, investing in Manchester's future. In this way, it's the political poster child for how we are going to decarbonize.
R18 added that unlike other political issues like immigration or health care reform, with decarbonization and HyNet "there is fresh political will to work together in a collaborative way." Indeed, the political dividends to be gained from HyNet could be significant. Net Zero North West (2022) notes the political (and economic) promise of lifting up the region with £285 billion in gross value added via the project, providing "social uplift," as well as developing a prospective workforce of 660,000 new and existing jobs across the North West, which would also have bragging rights as the "UK's first net zero region by 2040." As R02 captured succinctly, "HyNet is about the hydrogen economy, and across the whole economy, the region wants to be the leaders in developing the hydrogen economy for the UK." R32 agreed that "we're seeking to create that evidence to enable, not just those sites but, other sites around the UK to be able to have confidence to switch to hydrogen." R19 added that such reputation is even growing internationally, stating that:

Economic: a glaring planning and skills challenge
This frame challenges some of the elements of the technical and political frames above: one of a severe gap in capacity and skills that make an investment in HyNet risky and possibly even counterproductive if it fails. R18 spoke about how an adequately trained workforce, which is required, is problematic. As they explained: No, we don't have the skills to do CCS, hydrogen production, or hydrogen use. Some of the businesses involved recognize they have some of them in terms of gas fitters or technicians, but they also recognize the need to reskill, to move from natural gas to hydrogen gas. In the first workforce development study we led, there was no real sense of the scope and scale of that. They know it needs to happen, but are not sure how to go about it, they presume skills will just happen, they assume that the workforce will be ready, willing, and able at an affordable price, and that may not be the case.
As they concluded, in many cases: "Those skills don't yet exist." R22 likened the challenge to balancing "50 spinning plates" and that at any moment they could come crashing down if the skills or capacity do not exist to manage the project well. R20 remarked on some of the difficulties in skills as well, questioning: Who is providing the skills? Who is ensuring the industry supply chain has the competence to build this? Who is giving health and safety assurance, what's the capacity of the executive decision-makers in this space? Planning, I don't think planning academics have engaged at all, land use planning, permitting and environmental assessment and appraisal. These skillsets are all missing.
Other skills problems and gaps are more intuitive, and relate to existing skills or labor. R18 again spoke about how: Another huge gap is construction skills, even traditional construction skills. Yes, yes, it is numbers of people, they are just not there. Welding is a good example, there are not enough welders … and it is not just the fact that there is not enough welders-I use that example, but the whole construction and building skills supply chain is problematic.

R19 agreed and also stipulated that:
The skills gap, honestly, is likely to be in construction … We've got all of these major infrastructure projects all going on. That's where we're likely to hit a constraint, just having enough construction workforce to build it all.
In the extreme, some respondents expressed concern that the focus on "net-zero" and "green jobs" could even alienate existing workers who may have the necessary skills in welding, construction, or pipeline assembly. As R23 put it: You know, a lot of the political narrative is around masses of new low carbon green jobs. And I think there's a risk. There could be an element of that, but there's a risk that if you use that kind of language, you start to alienate the non-green workforce. You begin to think that there's no future for them.
R29 expanded on this aspect as well, arguing that "existing plans are looking so far ahead to the future, they risk tripping over their feet when trying to get there."

Socioenvironmental: an environmental boondoggle over gas
Our final HyNet frame is also more critical, and it sees HyNet as environmentally damaging given its reliance on fossil fuels and the nearterm contribution it could make to climate change. As R02 cautioned, There is still a tainted public image concerning natural gas from the failed fracking process, lots of distrust. There is a degree of skepticism about blue hydrogen among many civil society and local partners, who see it as promoting fossil fuel use, when instead it should be green hydrogen. HyNet is facing opposition from lots of local greens. One of the challenges is that legacy of fracking, how it will play out in public dialogues, there are poignant battle scars from the fracking industry. If there is any association between the CCS side of it and fracking, there will be very difficult conversations to be had, some trust was lost during the fracking debacle.

R16, a sponsor of HyNet, admitted that:
We do have challenges from environmental groups, because that's their job to do that … whether it's Friends of the Earth or if it's Greenpeace, they're unlikely ever to agree with blue hydrogen … So you're never going to change that really … they're never going to agree … Friends of the Earth is never going to support us because we are using natural gas. We have tried. There've been some efforts to convince them but, I think, when a group is ideologically opposed to something, even if logic might be on the other side, we're not going to convince them otherwise.
Moreover, R16 did agree with the association between HyNet and fracking, and how this is a challenge: The public attitude remains "Oh, this is all about the oil and gas industry trying to just keep their business going. And they did the same thing with fracking, and it was going to be in my backyard, and I don't like that." R23 explained how the region's experience with previous waves of industrialization may make them particularly opposed to further industrial projects. As they explained: In terms of social acceptance, there's also an element of, a feeling from some of the residents, possibly with a degree of justification that they've already got an awful lot of crap going on, on their patch. Dirty stuff, smelly stuff. Their stance is "Don't think that you can just come in and dump more here because there's some bad activities already happening here." These comments mimic statements made in the media, such as Jess Ralston from the Energy and Climate Intelligence Unit warning that "the government should be wary about being lobbied by the gas industry and committing too heavily to blue hydrogen, which still uses fossil fuels in its production and relies on [the] not-yet-ready technology [of] carbon capture and storage to reduce its emissions" (Quoted in Vaughan, 2021). Opposition has only intensified given recent scientific reports suggesting that blue hydrogen could be "worse for the climate than coal" (Howarth and Jacobson, 2021), which also attracted the interest of numerous newspaper articles that ran with that headline in the local and national media.

Discussion: eight frames in comparative and critical context
The eight illustrative frames associated with Zero Carbon Humber and HyNet are interesting not only empirically, but because they enhance our understanding of the social construction of, and social contestation with, these emergent industrial projects.

Problems, functions, risks and scale across frames
At their heart, each of the eight frames is pegged at some level to addressing some sort of problem or distinct dimension, or responding to another frameit therefore has a functionality or utility. This confirms earlier research which has suggested that the visions or expectations around new technologies are often functional by fulfilling some perceived social need, and by enabling proponents to capture resources (Geels and Smit, 2000). For instance, Eames et al. (2006) showed how earlier visions of a hydrogen economy touched upon six overarching problems: • Ending dependence on insecure supplies of energy; • Decentralizing energy via community ownership of energy systems and smaller and more distributed sources of supply; • Fundamentally reforming social values and towards sustainability; • Allowing humanity to retain its current lifestyles; • Harnessing technical progress, knowledge, and innovation; • Creating employment and staying in the international race for economic competitiveness.
When depicting hydrogen expectations as a solution to these problems, Eames et al. noted that such visions intentionally keep the boundaries and possibilities open and fluid, enhancing rhetorical appeal.
There is a similar degree of utility to the eight frames in Section 3, because those various dimensions (technology, economics, politics, social acceptance) always need to be addressed in any successful megaproject. Zero Carbon Humber is perceived as a complex machine that will demonstrate the feasibility of net-zero to the world, as well as a lever by which deprived regions of the UK can also build skills and "level up" their economies. HyNet is viewed as a stepping stone to a regional hydrogen economy that proliferates beyond industry to also commercial and residential sectors, as well as spreading to encompass mobility. For others, it represents a political posterchild for collaboration and crossparty consensus that other industrial clusters can learn from.
The eight frames also exhibit a plethora of different functions. The two projects both have a mix of technical functions such as delivering hydrogen to industry, storing and sequestering carbon, or enabling hydrogen spin-offs or complementarities with nuclear power or renewable energy. But they also shape political discussions, whether as a symbol of attaining regional balance for peripheral communities, or a worrying commitment to fossil fuels and a legitimation of gas and blue hydrogen. They touch upon economic dimensions, as a way of raising socioeconomic status and incomes, or a spotlight on skills and training challenges on the horizon. They lasty intersect with socioenvironmental issues, arising from pressures such projects place on social communities hosting infrastructure, seeing disruption of their routines, or climatic Fig. 8.

The arrows depict how relevant social groups (in blue) interact with frames (in red) which also shape both the technology (in black) and the solutions it can provide (in green). These in turn also seek to respond to, or are impeded by, particular risks (in purple). The system is thus dynamic and constantly sees social groups, frames, problems, and risks circulate and shift. Note: not all relevant social groups have equal importance for each project, nor are all frames equally resonant or impactful. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.) risks of embedding natural gas into UK supply chains and societies.
The eight frames also show starkly different degrees of valence and scale (see Fig. 7). Positive frames see the projects as benign and supportive infrastructures enabling net-zero pathways towards environmental sustainability, energy decentralization via a hydrogen economy, or greater leveling up and community control. These markedly differ from frames that envision them as tools of incumbency, contributors towards climate change and socioenvironmental degradation, or plans doomed to fail due to lack of adequate skills or traditional jobs in the construction sector. As Fig. 7 also depicts, some frames emphasize regional to global impacts (such as demonstrating worldwide leadership or contributing to global climate change) whereas others are more national to local (such as a leveling up of deprived areas or gaps in local skills).
In their work on the social construction of technology, Oti-Sarpong and Leiringer (2021) argue that frames, actor coalitions, problems, and solutions do not exist in isolation; they coevolve together as part of a complex sociotechnical system. We agree, and depict in Figs. 8 and 9 such coevolution for both Zero Carbon Humber and HyNet North West. As both Figures indicate, relevant social groups shape the interpretive frames, which are also designed to provide solutions to social challenges, like jobs, or innovation or security. In doing so, they also risk other problems, which can also shape the entire system. The particular risks facing each project are differentiated insofar as accidents and social opposition may be higher for HyNet (given what respondents identified as a more aware and litearate people of Merseyside), whereas aggregate fugutive emissions and cost overruns are more prominent given the scale and scope of Humber (almost twice as many emissions by volume that need to be captured, £10 billion more investment). The solutions each megaproject are intended to provide are also similar, although they exist in different configurations.
Although Figs. 8 and 9 do show variation between the frames and groups assocciated with both projects, the social groups for HyNet are fairly similar to those for Humber. The risks, solutions and technologies are also similar, which reinforces the finding that the differences between both projects (and their frames) may be less than their similarities.

Consensus, contestation and tradeoffs
Unlike frames within the SCOT literature that are more stabilized, such as those for bicycles or light bulbs, significant contestation exists within our frames, although some frames are more dominant than others, based on the frequency by which they are mentioned in our original data. As Table 3 indicates, no less than fifty separate actors are involved in some way in the eight frames advanced in Section 3. To be clear, this definition of relevant social groups does include those involved in the technology design process but also those (such as academics or community groups) in the broader social environment. However, positive frames were more dominant than negative ones from within our original data, showing up in a majority of interviews, whereas negative frames showed up in a minority of interviews. Frames are thus imbalanced in their frequency across the original interview data. Furthermore, some groups are in active conflict with other similar social groups in other frames, e.g. community groups and local politicians are involved in both positive and negative frames. In particular, HyNet sees a split between local political ambition, and what trade groups and associations think is possible, whereas there is no such split in Zero Carbon Humber. Fig. 9. Visualizing the relevant social groups, frames, solutions and risks to the Hynet North West megaproject Source: Authors, based on the Results mentioned in Section 3. The arrows depict how relevant social groups (in blue) interact with frames (in red) which also shape both the technology (in black) and the solutions it can provide (in green). These in turn also seek to respond to, or are impeded by, particular risks (in purple). The system is thus dynamic and constantly sees social groups, frames, problems, and risks circulate and shift. Note: not all relevant social groups have equal importance for each project, nor are all frames equally resonant or impactful.

Closure and stabilization
Our final thematic finding relates to closure and stabilization, or the lack thereof. For any given technology or sociotechnical system, closure or stabilization occurs when and if a social group and an artifact meld together; thus closure mechanisms can stabilize social groups as well as artifacts (Rood, 2017;Pozzebon et al., 2006;Brown et al., 2000). This can include rhetorical closure, when a social group perceives a problem as solved, or closure through redefinition, when an artifact stabilized incompletely by one social group is stabilized more by association with a larger or more powerful social group. Bijker and Law (1992: 10) emphasized that: Technology is stabilized if and only if the heterogeneous relations in which it is implicated, and of which it forms a part, are themselves stabilized. In general, then, if technologies are stabilized, this is because the network of relations in which they are involved-together with the various strategies that drive and give shape to the network-reach some kind of accommodation.
Thus, the concepts of closure and stabilization highlight that the design process of technology will inevitably continue until such differences are resolved.
When applied to our particular industrial decarbonization megaprojects, a degree of rhetorical closure is emerging, based on a preponderance of positive frames compared to negative ones within the interview data, but this closure is tentative, and is occurring before design closure occurs. Disagreement exists over the valence of each project (although negative frames were less dominant than positive frames, they still were present 10-20 % of the time across our data) as well as over critical design choices (green vs. blue hydrogen, pipeline routes and rights of way, coupling with renewables or nuclear power). Moreover, further destabilization could occur due to exogenous shocks, whether an unexpected hydrogen or carbon pipeline accident; or social opposition that solidifies once major construction projects begin causing communities inconvenience; or future energy shocks (like rising gas prices) make blue hydrogen production economically unviable. This underscores not only the lack of closure surrounding both projects, but great uncertainty over future development and the contingency of existing positive frames-which could be dominated by future negative frames in particular circumstances.

Conclusion
Conventional energy and industry policy analysts often view industrial decarbonization projects as technical mechanisms for delivering energy services or meeting climate objectives. Whenever more critical inquiry is undertaken, such assessments are usually about improving project performance, minimizing the risk of accidents, or ensuring adequate skills and financing to make the projects a reality. Contrary to such lines of thought, the research conducted here of Zero Carbon Humber and HyNet North West suggests that large net-zero megaprojects are also inherently economic, political, and socioenvironmental affairs. They can enable a leveling up of deprived areas or reflect the current status of regional skills development. They can politically signal the positive coalitions behind decarbonization or negatively signal the embedding of fossil fuel incumbency into the economy. They can interfere with local land use and contribute to climate change if implemented poorly. Examinations of net-zero projects that obscure these (sometimes invisible) social dimensions threaten to naturalize and depoliticize them.
Although the specific history surrounding Zero Carbon Humber and HyNet is unique, making it difficult to generalize findings to all or even most industrial net-zero projects, some commonalities, though contextual, do emerge. The first is that the SCOT framework, used previously for individual technologies or artifacts such as bicycles or light bulbs, is able to reveal meaningful aspects of megaprojects, which are in instead sociotechnical systems. A key component of the UK approach is a focus on multi-technology systems, where simultaneous innovations and developments in energy production and use (gas, hydrogen, renewables) will occur alongside hydrogen and carbon dioxide transport (pipelines, seaports, harbors) as well as hydrogen and carbon storage (in offshore depleted oil and gas fields, salt caverns). SCOT compellingly depicts the social dynamics of these systems even though they combine multiple artifacts to reach a common goal.
The second is that net-zero projects engender differing interpretive frames, and these frames can greatly shape their evolution. Indeed, this article has identified at least four separate frames per megaproject, held by a collective 50 sets of actors. These actors and stakeholders (which we call relevant social groups) have varying reasons for becoming invested in such frames and these can interact with the design of technology, the problems it seeks to address, and the risks entailed in doing so.
Additionally, although we have treated them as isolated, our two projects represent more complementary rather than contrasting cases, and affect each other. Both projects can complement each other, such as the HyNet academy supplying skills for all clusters; plus both can offer mutual learning that facilitates a "cross-pollination" of industrial cluster decarbonization. The two cases illustrate that a cluster approach to decarbonization can work for different regions, i.e. they can be adapted to scale, regional circumstances, and different relevant social groups. Both clusters aim to contribute to a Net Zero economy and both depend on government support and funding for decarbonization. They face similar challenges or selection pressures, but demonstrate that there could be different solutions and frames in terms of how to address them (e.g. HyNet Academy creating local workforce capacity versus addressing skills shortages across the country by paying more, or salt caverns versus empty gas fields for storage).
Moreover, although a degree of rhetorical closure has emerged concerning both megaprojects-that is, positive frames seem more recurrent and resilient than negative frames-this is tentative and connects with the relative influence of different actors and frames. Some actors, particularly industrial and policy stakeholders, who make the technical choices and shape the business models, currently have more influence than others, such as NGOs, citizens, and left-wing social scientists. Some of the frames being advanced by these powerful actors therefore have more resonance and efficacy than weaker frames, as evidenced by our content analysis of our expert interviews and illustrated in Table 3 above. Actors with more power and influence (policymakers, industry) have succeeded in stabilizing their frames (for now), and more critical frames are more marginal and less influential. This could change, of course, especially perhaps on the citizen side, once they start experiencing negative effects of construction. This reminds us that the strength and legitimacy of dominant frames is impermanent.
This point leads to a more cautionary finding: large, capital intensive net-zero megaprojects such as Zero Carbon Humber and HyNet will remain dependent on the proper constellation of social, political, and economic conditions to be completed. They both must satisfy varying interests and appease different stakeholders to get approved and built, all the while navigating particular risks across local to national to regional and global scales, contestation among social groups, and lack of closure and an inherently uncertain and temporary form of (current) closure. They remind us not only that industrial decarbonization and net-zero projects have a contested future; but also that the evolutionary pathway of such projects is a function not only of technology, but perceptions, frames, and functions within society.

IDRIC megaproject context interview questions (for the Humber case study)
Drivers: What are the main drivers behind industrial decarbonization megaprojects funded from the CCS infrastructure fund in the UK (Hynet and East Coast Cluster in 1 st round, potentially Acorn/Scotland and other ones in 2 nd round) • Decarbonization?
One or multiple projects?
• The Humberside cluster has several projects, which are funded differently and led by different organisations, e.g., (1) Zero-Carbon Humber part of East Coast Cluster, funded from CCS infrastructure fund, (2) Humber Zero, funded by Innovate UK, (3) Green Hydrogen for Humberside, funded from the Industrial Strategy Challenge Fund. Do you see these as separate projects, or as sub-projects of a larger megaproject? If they are separate, do you envisage or hope that they will combine in the future? Any synergies between them?

Visions and plans:
• What sorts of benefits could decarbonization megaprojects bring?
• How credible and viable are current plans, what's the feasibility of these megaprojects, what are the chances that they will be implemented as planned? • What are the main strengths and weaknesses of each cluster proposition/plan? Major differences? (selection of Track 1 megaprojects) • How malleable are current plans? • How receptive are government or financial actors to the visions being put forth by megaproject sponsors, and to any changes to the original visions/plans (e.g. timeframe, costs, what is actually achieved, benefits, scale)?

Implementation negotiations:
• What is the current status of negotiations concerning implementation of the industrial decarbonization projects that were selected in the first round of the CCS Infrastructure Fund?
Technologies and systems: Do UK companies have sufficient skills to develop and deploy the relevant technologies (e.g., CCS, hydrogen production, hydrogen use)? Or do you anticipate particular technical bottlenecks or areas of uncertainty, which may preclude large-scale commitment?
Governance: These megaprojects are very large, complex, involve many partners, and several radically novel technologies. Is the project management designed to accommodate likely or potential setbacks, surprises, or partial failures, which often characterise the development and deployment of radical innovations?
Other implementation barriers: What other barriers/challenges will they face? What struggles and conflict of interests might occur? "Competition" between megaprojects/technologies/companies? IDRIC megaproject interview questions Technology implementation, experimentation and knowledge: • Where did the idea [for this particular megaproject] come from? Whose idea was it? • What are the specific implementation and deployment plans (including the role of learning, experimentation, knowledge sharing, stakeholder engagement, risk/reward sharing)? • What are the technical skills and capabilities needed for each megaproject? • What are the main challenges?

Visions and value propositions:
• What are the technical and commercial visions, including costs and value propositions (which may linked to green hydrogen, green electricity/BECCS or other values)? How these visions have evolved? • Who will finance the megaprojects, what are the potential business models? • What is the competitive advantage for doing this within the UK?

Actors, coalitions and social acceptance/legitimacy:
• Who are the lead actors and broader coalitions for each project, and what are their motivations and interests? Who is not involved? • What is the degree of collaboration and alignment within these coalitions? Any changes overtime? • What interactions occur with broader stakeholders such as government and local communities?

Policy and governance:
• How do the megaprojects sit within the wider cluster context, both in terms of governance (within and across government departments, cluster governance in relation to these, local/regional government etc.) and in terms of the wider policy and regulatory landscape? • How consistent are the support policies for megaprojects with wider energy, industry and trade policy, climate policy, safety and environmental regulation, informal rules of thumb and routines inside companies, corporate governance?
