Hydrogen In An International Context

Hydrogen in an International Context: Vulnerabilities of Hydrogen Energy in Emerging Markets describes strategies and developments for hydrogen civilization efforts realised by various stakeholders such as authorities, institutes, research, industry, and individuals, in different countries and at different stages of the development cycle. Through their contributions, the chapter authors in this book propose a new approach to actual and relevant topics of interest, generically called the hydrogen economy and civilization.Hydrogen vulnerabilities is a topic that includes new challenges that face the hydrogen energy market. Weaknesses for the hydrogen stakeholder are becoming more refined, and it is necessary to be an active and sensitive player to understand these. A prosperous development of hydrogen will require the assimilation of numerous, diverse and unfamiliar contexts. Challenges for hydrogen will not only be in scientific, technical, economical or public acceptance, but challenges also lie in the genesis of this topic and the neglect of some aspects, however marginal, which negatively influence the desired hydrogen developed.This book informs the reader about the status of hydrogen energy in the international market, and it includes a series of examples and case studies about hydrogen activities in various countries. Thus, due to the synergy of this library of contexts, the reader should be able to reach a level of intuition enabling them to see the strengths and weaknesses of hydrogen.

With special reference to India.

This book presents an international perspective on examining and putting into practice new innovations in science education. The chapters are organized into three parts, each of which addresses a key area in science education research. Part I of this book (Students’ conceptual understanding of science) addresses issues related to the identification of students’ science concepts, and the influence of everyday understandings on the construction of science concepts. Part II (Making science concepts plausible for students) addresses the pedagogical concerns of teachers in making science ideas plausible and logical for their students. Part III (Science teacher learning) reports on science teacher learning in Australia and Hong Kong. The focus is on the interaction between research and implementation, or how theory can be realized in classroom practice, with contributions from both non-Western and non-English-speaking contexts and Western and English speaking countries. Taken together, the papers have a common focus on the relationship or integration of theory and practice in science education. They demonstrate a concern to address education reform directions, putting into practice recommendations from science education research, and improving the quality of science education. The contributors of this book come from seven different areas around the world. These contributions have been essential in making the discussions in this book multi-perspective and relevant to an international audience, thus allowing it to emerge to join the international discourse on improving science education. The studies reported in this book provide insights for future research addressing science education reform directions, students’ learning needs and different classroom contexts. The discussions and the findings reported are relevant to science educators, teachers, student teachers, graduate students in education, curriculum developers and those responsible for education policy.

This open access book is a comprehensive exploration of European hydrogen policy, examining its development at both the EU level and in key Member States, while also considering the geopolitical implications of the emerging hydrogen landscape. The editors begin by framing Europe's position within the global hydrogen economy and present an analytical framework for assessing EU and Member State strategies within this context. The book delves into the evolution of EU hydrogen policy since the launch of its hydrogen strategy in 2020, shedding light on significant developments and how they have been influenced by events like Russia's invasion of Ukraine. It then proceeds with in-depth chapters dedicated to key EU Member States and Norway. Each country chapter examines domestic and international hydrogen policies, offering insights into important stakeholder interests, as well as the broader energy and foreign policy considerations shaping the evolving policy landscape. Special attention is given to the international dimension of these strategies, encompassing bilateral and multilateral engagements. In the final chapter, the editors analyze the diverse national strategies and their drivers and discuss their implications for the development of a European hydrogen economy and the role of the EU as a major global player in this market. By examining the variations across Member States, the book provides valuable insights into the factors influencing progress in the hydrogen sector, both in Europe and globally. This book is a resource for policymakers, researchers, and industry professionals seeking a comprehensive understanding of European hydrogen policy and its geopolitical implications. It illuminates the complex dynamics between EU-level strategies and the approaches adopted by individual Member States, ultimately contributing to a broader comprehension of Europe's position within the global hydrogen arena.

Biohydrogen Production: Fundamentals and Technology Advances covers the fundamentals of biohydrogen production technology, including microbiology, biochemistry, feedstock requirements, and molecular biology of the biological hydrogen production processes. It also gives insight into scale-up problems and limitations. In addition, the book discusses

In a world faced with massive and ever-growing energy demands where the environment is an important factor, an array of new technologies and or fuels are becoming a necessity, not a choice. Hydrogen may be one of those alternatives. Hydrogen can be produced from diverse domestic feedstocks using a variety of process technologies. Hydrogen-containing compounds such as, fossil fuels, biomass or even water can be a source of hydrogen. Thermochemical processes can be used to produce hydrogen from biomass and from fossil fuels such as coal, natural gas and petroleum. Power generated from sunlight, wind and nuclear sources can be used to produce hydrogen electrolytically. Sunlight alone can also drive photolytic production of hydrogen from water, using advanced photoelectrochemical and photobiological processes.

This book examines the visions, fantasies, frames, discourses, imaginaries, and expectations associated with six state-of-the-art energy systems—nuclear power, hydrogen fuel cells, shale gas, clean coal, smart meters, and electric vehicles—playing a key role in current deliberations about low-carbon energy supply and use. Visions of Energy Futures: Imagining and Innovating Low-Carbon Transitions unveils what the future of energy systems could look like, and how their meanings are produced, often alongside moments of contestation. Theoretically, it analyzes these technological case studies with emerging concepts from various disciplines: utopianism (history of technology), symbolic convergence (communication studies), technological frames (social construction of technology), discursive coalitions (discourse analysis and linguistics), sociotechnical imaginaries (science and technology studies), and the sociology of expectations (innovation studies, future studies). It draws from these cases to create a synthetic set of dichotomies and frameworks for energy futures based on original data collected across two global epistemic communities— nuclear physicists and hydrogen engineers—and experts in Eastern Europe and the Nordic region, stakeholders in South Africa, and newspapers in the United Kingdom. This book is motivated by the premise that tackling climate change via low-carbon energy systems and practices is one of the most significant challenges of the twenty-first century, and that success will require not only new energy technologies, but also new ways of understanding language, visions, and discursive politics. The discursive creation of the energy systems of tomorrow are propagated in polity, hoping to be realized as the material fact of the future, but processed in conflicting ways with underlying tensions as to how contemporary societies ought to be ordered. This book will be essential reading for students and scholars of energy policy, energy and environment, and technology assessment.
