Hydrogen has been recognised as a universal, clean fuel which is expected to provide energy to our homes, industry and automobiles in the future. It is considered as one of the most interesting alternat~ves to petroleum fuels. A considerable amount of research and development work on product ion, storage and transportation, and utilisation of hydrogen is in pro gress allover the world. In India, several institutions have been working on the various aspects of the hydrogen considering it as an energy vector. A three-day National Workshop on Hydrogen Energy was organised at Indian Institute of Technology (lIT) Delhi to focus attent ion on developments in hydrogen energy at national and international levels and to provide a forum to coordinate contemporary research trends in the country in this field. The presentations made at the Workshop covered the topics which are considered to be of significance to work out the perspective, problems and promises for the future for transition to hydrogen energy. The proceedings of the Workshop are reported in this book, which include the inaugural address, description of the national research and development programme in the field of hydrogen energy, papers presented on production, storage and transportation, and utilisation of hydrogen and the panel report. In the inaugural address, emphasis is laid on the need for a trans ition from the presently used fuels to the newer ones, preferably to those which are renewable and non-polluting such as hydrogen.

Hydrogen is high on the political and innovation agendas of many countries, research institutions and companies. It is an energy medium with great potential for contributing to a transition towards carbon-neutral energy, however, hydrogen sources are dominated by fossil fuels, and the technical and economic challenges remain considerable. This report provides an overview of current hydrogen and fuel cell technology trends internationally, and with a specific focus on developments and implementation in China.

The hazardous effects of pollutants from conventional fuel vehicles have caused the scientific world to move towards environmentally friendly energy sources. Though we have various renewable energy sources, the perfect one to use as an energy source for vehicles is hydrogen. Like electricity, hydrogen is an energy carrier that has the ability to deliver incredible amounts of energy. On-board hydrogen storage in vehicles is an important factor that should be considered when designing fuel cell vehicles. In this study, a recent development in hydrogen fuel cell engines is reviewed to scrutinize the feasibility of using hydrogen as a major fuel in transportation systems.

In a multidisciplinary field such as energy, Hydrogen and Fuel Cells stands out by covering the entire width of hydrogen production and usage technologies, giving detailed descriptions of not just one but the range of very different fuel cells that have been developed or are under development. In one volume, respected experts Bent Sorensen and Giuseppe Spazzafumo provide all the basic scientific theory underlying hydrogen and fuel cell technologies, but at the same time present applications and sustainable integration into society in a way accessible to a broad range of people working in this field, whether in technical, economic or management roles. The third edition reflects both recently emerged technologies and the market penetration of the most promising technologies, and it gives an appraisal of how far fuel cell technology may go in the future, considering current challenges and economic trends. This new edition has updated and expanded content on hydrogen storage and transmission, molten carbonate fuel cells, PEM fuel cells, solid oxide fuel cells, biofuel cells, including microbial fuel cells, applications in transportation and power plants, future scenarios and life-cycle assessment. It is ideal for researchers and professionals in the field of energy, and renewable energy in particular, both in academia and industry. It is also useful to lecturers and graduate students in engineering, physics, and environmental sciences, as well as professionals involved in energy or environmental regulation and policy. - Gain thorough understanding of the science and applications of hydrogen and a range of different fuel cells, including economic and social aspects of the field - Updated sections include hydrogen storage and transportation, biofuel cells, PEM and solid oxide fuel cells, applications in transportation and large scale power generation, and life-cycle assessment

The global energy scenario is undergoing an unprecedented transition. In the wake of enormous challenges—such as increased population, higher energy demands, increasing greenhouse gas emissions, depleting fossil fuel reserves, volatile energy prices, geopolitical concerns, and energy insecurity issues—the energy sector is experiencing a transition in terms of energy resources and their utilization. This modern transition is historically more dynamic and multidimensional compared to the past considering the vast technological advancements, socioeconomic implications and political responses, and ever-evolving global policies and regulations. Energy insecurity in terms of its critical dimensions—access, affordability, and reliability—remains a major problem hindering the socioeconomic progress in developing countries. The Handbook of Energy Transitions presents a holistic account of the 21st-century energy transition away from fossil fuels. It provides an overview of the unfolding transition in terms of overall dimensions, drivers, trends, barriers, policies, and geopolitics, and then discusses transition in terms of particular resources or technologies, such as renewable energy systems, solar energy, hydropower, hydrogen and fuel cells, electric vehicles, energy storage systems, batteries, digitalization, smart grids, blockchain, and machine learning. It also discusses the present energy transition in terms of broader policy and developmental perspectives. Further, it examines sustainable development, the economics of energy and green growth, and the role of various technologies and initiatives like renewables, nuclear power, and electrification in promoting energy security and energy transition worldwide. Key Features Includes technical, economic, social, and policy perspectives of energy transitions Features practical case studies and comparative assessments Examines the latest renewable energy and low-carbon technologies Explains the connection between energy transition and global climate change
