The North Sea Offshore Grid concept has been envisioned as a promising alternative to: 1) ease the integration of offshore wind and onshore energy systems and 2) increase the cross-border capacity between the North Sea region countries at low cost. In this paper we explore the techno-economic benefits of the North Sea Offshore Grid using two case studies: a power-based offshore grid where only investments in power assets are allowed (i.e. offshore wind HVDC/HVAC interconnectors); and a power-and-hydrogen offshore grid where investments in offshore hydrogen assets are also permitted (i.e. offshore electrolysers new hydrogen pipelines and retrofitted natural gas pipelines). In this paper we present a novel methodology in which extensive offshore spatial data is analysed to define meaningful regions via data clustering. These regions are incorporated to the Integrated Energy System Analysis for the North Sea region (IESA-NS) model. In this optimization model the scenarios are run without any specific technology ban and under open optimization. The scenario results show that the deployment of an offshore grid provides relevant cost savings ranging from 1% to 4.1% of relative cost decrease (2.3 bn € to 8.7 bn €) in the power-based and ranging from 2.8% to 7% of relative cost decrease (6 bn € to 14.9 bn €) in the power-and-hydrogen based. In the most extreme scenario an offshore grid permits to integrate 283 GW of HVDC connected offshore wind and 196 GW of HVDC meshed interconnectors. Even in the most conservative scenario the offshore grid integrates 59 GW of HVDC connected offshore wind capacity and 92 GW of HVDC meshed interconnectors. When allowed the deployment of offshore electrolysis is considerable ranging from 61 GW to 96 GW with capacity factors of around 30%.

This paper evaluates the potential of grid services in France Italy Norway and Spain to provide an alternative income for electrolysers producing hydrogen from wind power. Grid services are simulated with each country's data for 2017 for energy prices grid services and wind power profiles from relevant wind parks. A novel metric is presented the value of curtailed hydrogen which is independent from several highly uncertain parameters such as electrolyser cost or hydrogen market price. Results indicate that grid services can monetise the unused spare capacity of electrolyser plants improving their economy in the critical deployment phase. For most countries up-regulation yields a value of curtailed hydrogen above 6 V/kg over 3 times higher than the EU's 2030 price target (without incentives). However countries with large hydro power resources such as Norway yield far lower results below 2 V/kg. The value of curtailed hydrogen also decreases with hydrogen production corresponding to the cases of symmetric and down-regulation.

The Heads of Terms for the Low Carbon Hydrogen Agreement sets out the government’s proposal for the final hydrogen production business model design. It will form the basis of the Low Carbon Hydrogen Agreement the business model contract between the government appointed counterparty and a low carbon hydrogen producer.<br/>The business model will provide revenue support to hydrogen producers to overcome the operating cost gap between low carbon hydrogen and high carbon fuels. It has been designed to incentivise investment in low carbon hydrogen production and use and in doing so deliver the government’s ambition of up to 10GW of low carbon hydrogen production capacity by 2030.

The geographical understanding of directionality in the literature on mission-oriented innovation systems is still underdeveloped. Therefore this article reflects on whether the allocation of funding for R&D activities to different places can direct innovation systems in space. A placebased approach to the allocation of funding and its effects on innovation systems is developed to analyze how the German national government allocates funding to the national innovation system for hydrogen technologies. The results show that the allocation of funding considers placebased characteristics and has a range of systemic outcomes encompassing the clustering of research activities the specialization of certain places in certain market segments and the in crease of the spatial reach of the national innovation system by integrating left behind places. However the funding contributes insufficiently to market formation at the local and regional scale and is contested due to existing alternative routes that the innovation system could take.

Transformation concepts towards a low-carbon society often require new technology and infrastructure that evoke protests in the population. Therefore it is crucial to understand positions and conflicts in society to achieve social acceptance. This paper analyses these positions using the example of implementing hydrogen and carbon capture and storage infrastructure to decarbonise the German energy system. The empirical basis of the study are explorative stakeholder interviews which were conducted with experts from politics economics civil society and science and analysed within a discursive and attitudinal framework using qualitative content analysis. These stakeholder positions are assumed to represent dominant social perceptions and reflect chances and risks for acceptance. The results indicate different positions while pursuing the common goal of addressing climate change. The general conflict concerns strategies towards a low-carbon society especially the speed of phasing-out fossil energies. Regarding the combination of hydrogen and carbon capture and storage as instrument in the context of the energy transition the stakeholder interviews indicate controversial as well as consensual perceptions. The assessments range from rejection to deeming it absolutely necessary. Controversial argumentations refer to security of supply competitiveness and environmental protection. In contrast consensus can be reached by balancing ecological and economic arguments e.g. by linking hydrogen technologies with renewable and fossil energy sources or by limiting the use of carbon capture and storage only to certain applications (industry bioenergy). In further decisions this balancing of arguments combined with openness of technology transparency of information and citizen participation need to be considered to achieve broad acceptance.

For fast-tracking climate change response green hydrogen is key for achieving greenhouse gas neutral energy systems. Especially Sub-Saharan Africa can benefit from it enabling an increased access to clean energy through utilizing its beneficial conditions for renewable energies. However developing green hydrogen strategies for Sub-Saharan Africa requires highly detailed and consistent information ranging from technical environmental economic and social dimensions which is currently lacking in literature. Therefore this paper provides a comprehensive novel approach embedding the required range of disciplines to analyze green hydrogen costpotentials in Sub-Saharan Africa. This approach stretches from a dedicated land eligibility based on local preferences a location specific renewable energy simulation locally derived sustainable groundwater limitations under climate change an optimization of local hydrogen energy systems and a socio-economic indicator-based impact analysis. The capability of the approach is shown for case study regions in Sub-Saharan Africa highlighting the need for a unified interdisciplinary approach.

Morocco despite its heavy reliance on imported fossil fuels which made up 68% of electricity generation in 2020 has recognised its significant renewable energy potential. The Nationally Determined Contribution (NDC) commitment is to reduce emissions by 45.5% from baseline levels with international assistance and abstain from constructing new coal plants. Moreover the Green Hydrogen Roadmap aims to export 10 TWh of green hydrogen by 2030 as well as use it for local electricity storage. This paper critically analyses this Roadmap and Morocco’s readiness to reach its ambitious targets focusing specifically on an energy trilemma perspective and using OSeMOSYS (Open-Source energy Modelling System) for energy modelling. The results reveal that the NDC scenario is only marginally more expensive than the least-cost scenario at around 1.3% (approximately USD 375 million) and facilitates a 23.32% emission reduction by 2050. An important note is the continued reliance on existing coal power plants across all scenarios which challenges both energy security and emissions. The assessment of the Green Hydrogen Scenarios highlights that it could be too costly for the Moroccan government to fund the Green Hydrogen Roadmap at this scale which leads to increased imports of polluting fossil fuels for cost reduction. In fact the emission levels are 39% higher in the green hydrogen exports scenario than in the least-cost scenario. Given these findings it is recommended that the Green Hydrogen Roadmap be re-evaluated with a suggestion for a postponement and reduction in scope.

This study introduces a multi-period integrated optimization model for designing a strategic hydrogen supply chain (HSC) network concentrating on the post-production stages of conditioning storage transportation and post-conditioning. Qatar serves as the case study for evaluating three HSC pathways—ammonia (as a hydrogen carrier) liquefied hydrogen and compressed hydrogen—across pre-conditioning storage shipping and postconditioning stages. The optimization framework spans a 20-year plan supporting strategic long-term hydrogen export infrastructure planning. Economic and environmental factors are incorporated to analyze HSC performance under various scenarios accounting for realistic constraints such as investment limits and emission caps. Key findings reveal trade-offs between pathways and design strategies that must account for balancing costs with environmental impacts. Results indicate that the ammonia pathway is preferred in scenarios without emission penalties but becomes less favorable with increased penalties shifting preference toward the liquified hydrogen pathway. With stringent emission limits short- and mid-range markets are prioritized underscoring the importance of emissions-conscious strategies. This study demonstrates the utility of optimi zation tools in balancing economic and environmental objectives offering policymakers and industry stake holders a robust framework for developing sustainable and efficient HSC networks.

In recent years production and supply of hydrogen has gained significant attention within the German energy transition. This is due to increasingly urgent pressures to mitigate climate change and geopolitical imperatives to substitute natural gas. Hydrogen is seen as an important cross-sectoral energy carrier serving multiple functions including heat production for industry and households fuel for transportation and energy storage for stabilization of electricity supply. In the context of various funding mechanisms on several administrative levels regional value chains for green hydrogen supply are emerging. To date however few studies analyzing regional hydrogen systems exist. Due to its high projected demand of energy sources for heating industrial processes and mobility Germany appears to be a very relevant research area in this emerging field. Situated within the concept of the multi-level perspective this article examines the way how regional “niches” of green hydrogen evolve and how they are organized. The study takes an evolutionary perspective in analyzing processes of embedding green hydrogen infrastructures in regional energy regimes which entered “re-configuration”-pathways. It argues that the congruence of available resources for renewable electricity established networks of institutional entrepreneurs and access to higher level funding are conditions which put incumbent regime-actors in favorable positions to implement green hydrogen niches. Conversely the embedding of green hydrogen infrastructures in regional energy systems is a case in point of how the attributes of niches in particular technological domains can be used to explain the transition pathway entered by a surrounding energy regime.

The increasing political momentum advocating for decarbonization efforts has led many governments around the world to unveil national hydrogen strategies. Hydrogen is viewed as a potential enabler of deep decarbonization notably in hard-to-abate sectors such as the industry. A multi-modal hourly resolved linear programming model was developed to assess the infrastructure requirements of a low-carbon supply chain over a large region. It optimizes the deployment of infrastructure from 2025 up to 2050 by assessing four years: 2025 2030 2040 and 2050 and is location agnostic. The considered infrastructure encompasses several technologies for production transmission and storage. Model results illustrate supply chain requirements in Texas and Louisiana. Edge cases considering 100% electrolytic production were analyzed. Results show that by 2050 with an assumed industrial demand of 276 TWh/year Texas and Louisiana would require 62 GW of electrolyzers 102 GW of onshore wind and 32 GW of solar panels. The resulting levelized cost of hydrogen totaled $5.6–6.3/kgH2 in 2025 decreasing to $3.2–3.5/ kgH2 in 2050. Most of the electricity production occurs in Northwest Texas thanks to high capacity factors for both renewable technologies. Hydrogen is produced locally and transmitted through pipelines to demand centers around the Gulf Coast instead of electricity being transmitted for electrolytic production co-located with demand. Large-scale hydrogen storage is highly beneficial in the system to provide buffer between varying electrolytic hydrogen production and constant industrial demand requirements. In a system without low-cost storage liquid and compressed tanks are deployed and there is a significant renewable capacity overbuild to ensure greater electrolyzer capacity factors resulting in higher electricity curtailment. A system under carbon constraint sees the deployment of natural gas-derived hydrogen production. Lax carbon constraint target result in an important reliance on this production method due to its low cost while stricter targets enforce a great share of electrolytic production.

Public perceptions might determine the ease of the transition from a fossil-based to a green hydrogen-based production pathway in the industrial sector. The primary objective of this paper is to empirically identify the antecedents of the acceptance of two relevant industrial applications of green hydrogen: green methanol and green steel. The analysis relying on linear regression models utilises survey data from samples of residents near a chemical park and a steel plant (509 and 502 participants respectively) contrasting them with a representative sample of 1502 individuals in Germany. The findings suggest that acceptance of the transitions to green methanol and green steel is high both locally and nationally. In all surveys >59 % of the participants are in favour while the share of those who are opposed to the respective transitions is below 9 %. Key antecedents of acceptance which are conducive in all models relate to individuals’ attitudes towards green hydrogen and perceptions of the legitimacy of the industry actors involved with varying results across legitimacy types. In general the findings were similar across industrial applications and across levels of observation but varied across regions. This study highlights the importance of civil society perceptions and suggests that relationship management efforts aimed at maintaining positive perceptions of industrial hydrogen applications should consider their broader physical and social contexts.

A lot of countries have recently published updated hydrogen strategies with many of them increasing and renewing their commitment. In parallel corresponding policy mechanisms are increasingly coming into focus with the first ones already having awarded funding contracts to projects and construction being underway. However these policies are usually translated from renewable energy policy without considering the specific risks and uncertainties spillovers and positive externality of operating grid-conducive electrolyzers in electricity grids which are increasingly subjected to electricity supply volatility from renewables. This article details how different aspects of a dedicated hydrogen policy can address the technology’s specific issues from an economic perspective namely funding provision market and technology risk mitigation and the complex relationship with further actors in electricity markets. Results show that compared to renewable energy policy mechanisms need to emphasize the input side more strongly as price risks and intermittency from electricity markets are more prominent than from hydrogen markets. Also it proposes a targeted mechanism to capture the positive externality of mitigating excess electricity in the grid while keeping investment security high. Economic policy should consider such approaches before scaling support and avoiding the design shortcomings experienced with early RE policy.

This review article critically examines papers on renewable energy integration (REI) with a specific focus on the economic and environmental impact assessments across multiple sectors including agriculture transportation electricity production buildings and biofuel production. A total of 111 articles from the Web of Science Core Collection database were reviewed using a systematic literature review methodology and content analysis techniques. The results indicate that evaluation-type studies particularly those employing optimization and simulation-based methods such as techno-economic analysis (TEA) (28 papers) and lifecycle assessment (LCA) (20 papers) were the most prominent approaches used for economic and environmental analyses. Optimization techniques such as mixed-integer linear programming (6 papers) genetic algorithms (GA) (5 papers) and particle swarm optimization (PSO) (4 papers) were widely applied. The quantitative analysis of impact assessment indicators shows that REI has yielded significant long-term positive results across multiple RE sources sectors and regions. A detailed examination of mathematical models (e.g. optimization techniques) and simulation modeling combined with lifecycle assessment (LCA) will assist future researchers in optimizing energy systems and enhancing sustainability in sectors such as agriculture and water desalination. The conceptual inclusion of circular economy within the research field needs to be more present among researchers and most of the studies focused on technical aspects of RE integration and assessing impacts rather than identifying a systemic change across the sectors. Several future research directions have been identified across sectors offering opportunities to advance the field. Policymakers will find this paper valuable for informed decision-making and the development of robust policy frameworks.

In this latest OIES podcast James Henderson talks to Bill Farren-Price the new Head of the Gas Programme about some of Key Themes identified by OIES research fellows for 2024. After a review of the outcomes from 2023 we look at the oil and gas markets and discuss a common theme around the contrast between the fundamental tightness in both markets compared with the relative softness of prices. We then move onto a number of energy transition issues starting with some of the key actions from COP28 that need to be implemented in 2024 and following with a review of the outlook for carbon markets hydrogen developments and offshore wind. We also consider the impact of emerging competition between regions over green industrial policy. Finally we consider some of the key geopolitical drivers for 2024 with the influence of China being the most critical. However in an election year for so many countries it will be critical to follow the key policy announcements of the main candidates and of most critically the outcome of the US election in November.

This study uses a multi-method design to investigate the media’s role in shaping Germans’ attitudes toward green hydrogen. It combines an automatized content analysis of 7649 German newspaper articles published between July 2021 and June 2024 and a three-wave panel survey of the German population conducted between June 2023 and June 2024 with an initial sample of 2701 participants. The findings show that the intensity of media reporting on hydrogen was low compared to other energy-related topics. Nevertheless participants’ assessments of relative topic presence are rather accurate (rho: 0.50–0.80). A considerable number of participants were unable to position themselves toward the potential and challenges of hydrogen (23%–35%). Overall the results indicate that media and communication tend to stabilize or change existing attitudes rather than contribute to the formation or loss of attitudes leading to implications for the communication of relevant stakeholders.

Inspired by the announcement of the new Hydrogen Strategy for the UK in 2021 this study aimed to determine how the oil and gas industry responds and adapts to the changes. This paper analyses qualitative and quantitative data from the companies’ annual and energy reports. Four oil and gas companies involved in hydrogen projects in the UK were selected as case studies. The responses from the companies were collected using the content analysis research strategy in 2019–2021. A steady increase was observed based on the code frequency reflecting the increasing discussions and actions the companies took regarding this hydrogen pathway. Although only one company appears to be at the forefront of this transition progress with a score of almost 90% based on the strategy management analysis other companies continue to demonstrate their commitment to supporting the national target.

Since the Industrial Revolution humanity has heavily depended on fossil fuels. Recognizing the negative environmental impacts of the unmoderated consumption of fossil fuels including global warming and consequent climate change new plans and initiatives have been established to implement renewable and sustainable energy sources worldwide. This has led to a rapid increase in the installed solar and wind energy capacity. However considering the fluctuating nature of these renewable energy sources green hydrogen has been proposed as a suitable energy carrier to improve the efficiency of energy production and storage. Thus green hydrogen produced by water electrolysis using renewable electricity is a promising solution for the future energy market. Moreover it has the potential to be used for the decarbonization of the heavy industry and transportation sectors. Research and development (R&D) on green hydrogen has grown considerably over the past few decades aiming to maximize production and expand its market share. The present work uses a SWOT (strengths weaknesses opportunities and threats) analysis to evaluate the current status of the green hydrogen market. The external and internal factors that affect its market position are assessed. The results show that green hydrogen is on the right track to becoming a competitive alternative to fossil fuels soon. Supported by environmental benefits government incentives and carbon taxes roadmaps to position green hydrogen on the energy map have been outlined. Nevertheless increased investments are required for further R&D as costs must be reduced and policies enforced. These measures will gradually decrease global dependency on fossil fuels and ensure that roadmaps are followed through.

Hydrogen is viewed as a potential energy solution for the 21st century with capabilities to tackle issues relating to environmental emissions sustainability energy shortages and security. Even though there are potential benefits of renewable hydrogen towards transitioning to net-zero emissions there is a limited study on the current use ongoing development and future directions of renewable hydrogen in Australia. Thus this study conducts a systematic review of studies for exploring Australia’s renewable hydrogen energy transition current trends strategies developments and future directions. By using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines earlier studies from 2005 to 2024 from two major databases such as ProQuest and Web of Science are gathered and analyzed. The study highlights significant issues relating to hydrogen energy technologies and opportunities/challenges in production storage distribution utilization and environmental impacts. The study found that Australia’s ambition for a strong hydrogen economy is made apparent with its clear strategic actions to develop a clean technology-based hydrogen production storage and distribution system. This study provides several practical insights on Australia’s hydrogen energy transition hydrogen energy technologies investments and innovation as well as strategies/recommendations for achieving a more environment friendly secure affordable and sustainable energy future.

Hydrogen presents the UK with a substantial opportunity to drive economic growth and secure skilled jobs by leveraging our natural geological and geographical advantages robust supply chain and existing energy expertise. Hydrogen UK’s most recent Economic Impact Assessment estimates that the hydrogen sector in the UK could support approximately 30000 direct jobs and contribute more than £7 billion gross value added annually by 2030. On a global scale the hydrogen market is projected to be worth $2.5 trillion by 2050.

With international competition increasing the UK must act now to capitalise on this potential. These projections are supported by a recognition that hydrogen is one of the key solutions to decarbonising the UK economy complementing other low-carbon solutions such as electrification carbon capture biofuels and energy efficiency. Additionally hydrogen will play a vital role in enhancing the UK’s energy security by storing domestically produced energy to balance intermittent renewable sources like wind and solar. As a critical component of the clean energy transition hydrogen is indispensable to achieving net zero.

As it stands the UK is well placed to capitalise on the hydrogen opportunity and emerge as a global leader. We have made early strides in establishing a framework for hydrogen development with various pilot projects and strategic investments already underway. However the next five years will be critical for the sector as we move from strategy and planning to development and delivery. It is imperative to get the first lowcarbon production projects over the line and into construction as a matter of urgency and then deliver substantial infrastructure development regulatory clarity and sustained financial support to scale-up production and distribution. A new Government presents an opportunity for policymakers to solidify commitments and accelerate the deployment of hydrogen technology ensuring the UK remains competitive in the global race.

Our manifesto outlines policy recommendations for the new UK Government to take across production distribution and storage infrastructure end use applications trade and beyond which will support a thriving British industrial base that creates jobs and growth for British people. To achieve this the UK hydrogen industry calls on policymakers to speed up the deployment of hydrogen through the recommendations set out in this Manifesto.

Hydrogen is one of the key solutions to decarbonising the UK economy along with other carbon abatement solutions such as electrification CCUS biofuels and energy efficiency. It provides a low carbon alternative to fossil fuels that has many of the same desirable features such as burning with a high temperature flame without producing carbon emissions during combustion. Hydrogen will be particularly valuable in hard-to-decarbonise sectors that have few cost-effective alternatives including elements of industry heavy transport and dispatchable power generation. However it’s use could be much more widespread depending on how costs preferences and policy for different low carbon solutions develop. The Government’s Hydrogen Strategy estimates that based on analysis from the Climate Change Committee (CCC) in 2050 between 20% and 35% of the UK’s final energy demand could be met with low carbon hydrogen1 . While hydrogen provides a promising solution to reducing emissions current deployment of low carbon hydrogen is low with almost all hydrogen in the UK produced from unabated fossil fuels resulting in high emissions. In the UK hydrogen production must meet the Low Carbon Hydrogen Standard (LCHS) to access government support. This is currently set at 20g CO2 e/MJ(LHV) and will ensure that future deployment will deliver significant emissions reductions when switching from fossil fuels2. The period to 2030 will be a critical time for the UK to seize the economic opportunity presented by low carbon hydrogen sector. Internationally increasing attention has been placed on hydrogen as a solution to global emissions. In the USA the Inflation Reduction Act (IRA) has provided fixed rate tax credits of up to $3/kg (£2.4/kgII) for clean hydrogen production3. Closer to home the EU is targeting 10 million tonnes of domestic electrolytic production and an additional 10 million tonnes of electrolytic hydrogen imports by 20304. This will be achieved through a variety of policy levers including an auction for fixed price subsidy support for electrolytic production with a ceiling of €4.5/kg5 (£3.84/kgIII). In the UK Government have set an ambitious target of up to 10 GW of low carbon hydrogen production by 2030 with at least half of this from electrolytic sources6. This will be supported by the Hydrogen Production Business Model (HPBM) a two-way variable CfD which could potentially provide hydrogen for a price as low as the natural gas price7 . As global supply chains investment and skills are in international competition the UK must continue its ambitious hydrogen aspirations to ensure the decarbonisation and economic opportunity presented by low carbon hydrogen is captured. This study estimates the economic impact of the low carbon hydrogen sector in the UK by 2030. The impact is assessed by estimating the costs of hydrogen deployment and applying employment and GVA multipliers to these costs based on historic economic activity. These estimates are broken down by different forms of low carbon hydrogen production and end use as well as the enabling infrastructure required to connect production and demand namely hydrogen networks and storage. Both the employment and GVA are estimated for each of these value chain elements for every year between 2024 and 2030. Employment and economic growth from the hydrogen sector will be created across the UK with many benefits arising in regions that have faced historic underinvestment such as the industrial clusters and Scotland. Beyond the high-level economic benefits estimated in this study the hydrogen sector creates an opportunity for the hundreds of thousands oil and gas sector jobs in the UK to transition to a low carbon alternative.

Future pathways for Great Britain’s energy system decarbonization have highlighted the importance of lowcarbon hydrogen as an energy carrier and demand flexibility support. However the potential application within various sectors (heating industry transport) and production capacity through different technologies (methane reformation with carbon capture biomass gasification electrolysis) is highly varying introducing substantial uncertainties for hydrogen infrastructure development. This study sets out infrastructure priorities and identifies locational flexibility for hydrogen supply and demand options. Advances on limitations of previous research are made by developing an open-source model of the hydrogen system of Great Britain based on three Net Zero scenarios set out by National Grid in their Future Energy Scenarios in high temporal and spatial resolution. The model comprehensively covers demand sectors and supply options in addition to extending the locational considerations of the Future Energy Scenarios. This study recommends prioritizing the establishment of green hydrogen hubs in the near-term aligning with demands for synthetic fuels production industry and power which can facilitate the subsequent roll out of up to 10GW of hydrogen production capacity by 2050. The analysis quantifies a high proportion of hydrogen supply and demand which can be located flexibly.

Transitioning from carbon-intensive steam methane reforming to low-carbon hydrogen production is essential for decarbonizing the European industrial sector. However the employment impact of such a transition remains unclear. Here we estimate the effects using a transition pathways optimization model and industrial survey data. The results show that an electrolysis-based hydrogen sector transition would create 40000 jobs in the hydrogen sector by 2050. However these jobs are not equally distributed with Western Europe hosting the largest share (40%) and 20% of current hydrogen-producing regions experiencing net job decreases. Even after accounting for renewable energy jobs created by electrolysis-driven electricity demand growth the 2050 low-carbon hydrogen workforce would provide only 10% of the jobs currently offered by European fossil fuel production. Numerous uncertainties and regional development inequities suggest the need for sector-diversified workforce transition plans and training programs to foster skills suited to multiple low-carbon opportunities.
