Assessment Of Hydrogen Energy For Sustainable Development

Fossil fuel prices continue to rise and, at the same time, environmental policies are demanding a reduction in greenhouse gases and toxic emissions. A coherent energy strategy is needed: one that addresses both energy supply and demand and takes into account the whole energy lifecycle, from fuel production to the end-users of energy systems. This book examines hydrogen energy technologies and infrastructure development.

Sustainable Hydrogen Production provides readers with an introduction to the processes and technologies used in major hydrogen production methods. This book serves as a unique source for information on advanced hydrogen generation systems and applications (including integrated systems, hybrid systems, and multigeneration systems with hydrogen production). Advanced and clean technologies are linked to environmental impact issues, and methods for sustainable development are thoroughly discussed. With Earth’s fast-growing populations, we face the challenge of rapidly rising energy needs. To balance these we must explore more sustainable methods of energy production. Hydrogen is one key sustainable method because of its versatility. It is a constituent of a large palette of essential materials, chemicals, and fuels. It is a source of power and a source of heat. Because of this versatility, the demand for hydrogen is sure to increase as we aim to explore more sustainable methods of energy. Furthermore, Sustainable Hydrogen Production provides methodologies, models, and analysis techniques to help achieve better use of resources, efficiency, cost-effectiveness, and sustainability. The book is intellectually rich and interesting as well as practical. The fundamental methods of hydrogen production are categorized based on type of energy source: electrical, thermal, photonic, and biochemical. Where appropriate, historical context is introduced. Thermodynamic concepts, illustrative examples, and case studies are used to solve concrete power engineering problems. Addresses the fundamentals of hydrogen production using electrical, thermal, photonic, and biochemical energies Presents new models, methods, and parameters for performance assessment Provides historical background where appropriate Outlines key connections between hydrogen production methods and environmental impact/sustainable development Provides illustrative examples, case studies, and study problems within each chapter

Carbon neutral hydrogen technologies play a key-role in preventing climate change and hydrogen is really at the heart of the energy transition. As we can produce heat and power directly from hydrogen in a clean way, we will have many applications in the growing hydrogen economy. This book presents the current state and latest development trends of hydrogen economy with the focus on applications. It gives an overview of the hydrogen utilization as it relates to the transport technology, such as automobiles, heavy-duty vehicles, trains, ships, air, and space transport and industry. Large attention is given to structural and functional materials science, technologies and innovations with focus on the development of new materials and electrolytes for specific applications. Strictly related to mobility is the relation between vehicles and refuel stations, the safety analysis, risk assessment for both infrastructures and transport. Ideal book for students of materials science, chemistry, physics; for researchers and chemical- and mechanical engineers, for industrialists, policymakers, safety agencies and governments.

The present global environmental condition is critical. Paris Summit 2015 on climate change is a burning example how much politicians are concerned about the deteriorating conditions of the world. It is well advertised and propagated information that fossil fuels are not everlasting. Therefore, there is need to search renewable sources of energy. Plants and microbes are wonderful gift of nature for humankind. They have great potential to solve our any problems. They are also great scavengers who can clean the environment but greedy humans have victimized them and brutally remove them for uneven development of the world. An attempt has been made through this book, how tiny organisms like bacteria, cyanobacteria and microalgae could be used to generate hydrogen from them, what are the methods and techniques, how we can increase the H2 production, what are the mechanisms of storage of H2 and all such information is given in this book. Besides this how we can achieve sustainable development through biologically produced H2 is also mentioned. Overall, it is a good collection of information for those who are working on hydrogen energy and sustainable development programmes.

This work presents a comprehensive investigation of the most significant renewable hydrogen production processes. Technical, economic and ecological studies are described for the processes of steam reforming of ethanol, natural gas and biogas; water electrolysis with energy from renewable sources (wind power, photovoltaic and hydroelectric), and hydrogen production using algae. Aimed at mechanical and chemical engineering graduate students and researchers involved in environmental sciences, sustainable energy and bioenergy research, this book introduces readers to the latest developments in the field and provides essential reference material for future research. The book first presents a comprehensive literature review of the processes studied. Subsequently, it provides a technical report on assessing the energetic efficiency for each hydrogen production process, as well as an economic study of the respective hydrogen production costs. Lastly, the ecological efficiency of each process is addressed. Over the past few decades, the UNESP’s Group of Optimization of Energetic Systems, headed by Professor José Luz Silveira, has been pursuing research in the field of renewable energy generation. A major part of the group’s research focuses on the production of hydrogen as a fuel and its important contribution to mitigating the environmental impacts caused by pollutant emissions.

Hydrogen economy represents the future of human civilization. Limited resources of our planet are compelling us to turn to renewable clean energy resources and hydrogen figures prominently as the energy carrier of a future sustainable energy system. There are significant challenges to be overcome in order to make hydrogen viable, in production, storage and power generation, while safety of operation is an ever-present factor that determines success or failure of a proposed solution. Recent developments in all of these aspects are reviewed in this book, along with some latest research in the field of hydrogen energy and use.
