The Association of Southeast Asian Nations (ASEAN) Member States are increasingly focusing on alternatives to electrolysis for the production of ‘green’ hydrogen, such as steam reforming of biofuels and biomass gasification. This chapter analyses the possibility of effectively achieving that under the existing general regulatory framework on energy production, namely the laws on the establishment and operation of factories, as well as environmental protection laws in ASEAN countries that regulate hydrogen production, with special attention on biomass gasification and steam reforming of biofuels. It finds that, despite falling outside of energy regulatory frameworks, hydrogen production from biomass/biofuels is regulated under general legal frameworks on manufacturing activities, occupational health and safety, as well as environmental protection laws. This is demonstrated in more detail by referring to a case study on Thailand. The chapter argues that, in the absence of robust criteria on hydrogen classification, it is possible for an electricity producer that generates electricity from grey hydrogen to gain financial benefits that were formerly thought to be reserved for the promotion of ‘green’ electricity production from blue or green hydrogen, in the case of re-electrification of hydrogen after storage.

This chapter discusses the permitting regime for electrolysers in Aotearoa New Zealand. Because green hydrogen is typically converted from water via electrolysis, hydrogen projects are dependent upon electrolysers – and, therefore, upon obtaining the necessary consents to build and operate these. However, New Zealand’s resource consent rules do not specifically provide for permitting electrolysers. Instead, resource management legislation provides for consent to be obtained for use of those resources that will be needed for (and impacted by) the electrolyser operation, with health and safety rules and industry standards prescribing the specifications for electrolysers and the way these can be used. The chapter asks what permits will be needed and what processes must be followed in order for an electrolytic hydrogen project to receive resource consent. While examining the consenting process, the chapter also considers whether New Zealand’s existing regulations can support its hydrogen aspirations.

This chapter analyzes the interconnections between energy policy and security and defense policies in the UK, zooming in on Scotland. It explains the energy and security regimes and analyzes policy interplay. The links between hydrocarbon energy, energy transition, and security are complex, with relatively fragmented governance in place. While some instances of policy integration were found, broader policy coherence regarding security and the zero-carbon energy transition was lacking. Before 2022, coordination efforts were focused on external, global energy questions instead of domestic energy. Domestic energy security was driven by market-based values. Post-2022, security and energy transition links pertaining to domestic energy production and use became more important in political and policy agendas. Scotland has had a differing worldview on security in relation to energy transition than the rest of the UK, with more focus on the environmental and health security effects of energy policy choices and just transitions, evident, for instance, in its opposition to nuclear power.

This chapter explains what has been meant by energy security in different periods and research contexts. It elaborates on the history of energy security research and creates a typology of internal and external dimensions of energy security. Subsequently, the chapter describes the research on the geopolitics of energy, focusing on the geopolitics of renewable energy and the different implications envisaged to unfold from the energy transition. The chapter ends with a brief summary of the EU’s approach to energy security. The chapter, thereby, creates a research context for the empirical analyses conducted in this book.

This chapter introduces the topic of the book, namely the interconnections between zero-carbon energy transitions and security, and why this topic is of importance. It creates a setting for the following chapters by explaining the status of the energy transition in Europe, and introducing the academic fields the book draws from: sustainability transition studies, security studies, and studies of policy coherence and integration. The chapter also describes the research methods used and a brief background to the country cases, followed by a summary of the contents of the book.

Mining relates to violence in diverse ways, and frequently the relationship includes environmental violence. New technologies, including those central to a clean energy transition, mean that mining will remain a necessary industry. This means in turn that the human community will remain in need of ways to minimize and cope with the environmental violence of mining. The theory and practice of Catholic peacebuilding can offer distinct resources for dealing with these challenges. First, there is Catholic social teaching, which creates a foundation from which to respond to the environmental violence of mining in suitably complex and integral ways. Second, the Catholic community has a vibrant base of grassroots actors defending people and the environment from mining damage. And third, there is the church’s institutional capacity to network those grassroots actors and coordinate their work with national and international efforts to change resource governance and industry practice. The argument is not that these resources are necessarily unique to the Catholic community. The idea is that the Catholic community can array and marshal these resources in a distinctive way that gives it special potential for responding to mining and environmental violence.

This chapter addresses the legal dimensions of the European Union’s response to the climate change crisis. It introduces the EU’s climate governance strategy for 2030 and 2050, and reviews the key Regulations, Directives and legislative proposals adopted in its pursuit, including the European Climate Law, the Emissions Trading Directive, the Renewable Energy Directive and the proposed Carbon Border Adjustment Mechanism Regulation. The chapter discusses the position of the EU both as a key contributor to and a subject of international climate change law, and considers the relation between climate change as a governance challenge and the general principles of EU law, with a focus on solidarity, transparency and public participation. The chapter also examines the regulatory and enforcement strategies that characterise EU climate change law. To this end, the EU Emissions Trading System is examined as an example of the EU approach to market-based regulation, and the Governance Regulation demonstrates the EU’s reliance on ‘soft’, proceduralised enforcement in the climate policy sphere. The chapter’s final section illustrates the difficulty of coherent climate change decision-making, as EU authorities must reconcile internal market goals with energy security demands, sustainability concerns and global fairness concerns.

Industrialization could not have happened without abundant, easy-to-store-and-transport fossil fuels (coal, oil and gas). They and the technologies that mined, traded, processed and used them satisfied needs which they also created (including wars). They provided the heat, power and feedstock to run factories, operate transport systems and shape household living conditions (space heating--cooling, appliances). Energy use has exponentially risen in the last two centuries, to an average 2 kW/cap for poor and over 20 kW/cap for rich people, and supply is still dominated by fossil fuels. Modernization has become closely linked to provision of ’modern’ energy carriers (energy ladder). Apart from corporate and state super-profits and power and associated turmoil, it has brought enormous environmental destruction and harm, some of it affecting many generations to come. The most serious impact, climate change from greenhouse gas emissions, is stimulating a transition away from fossil fuels and towards efficient use and non-carbon supply (renewable, nuclear). This process is confronted with the divergence in worldviews, around issues such as risks, use of land and materials, lifestyle changes versus high-tech, role of decentral versus central supply, and private or public ownership.
