Green Hydrogen Generation

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.

Solar-Driven Green Hydrogen Generation and Storage presents the latest research and technologies in hydrogen generation through solar energy. With in-depth coverage of three key topics, the book discusses green hydrogen technologies, solid hydrogen storage, and hydrogen energy applications. The book begins with a deep dive into photoelectrochemical water splitting, examining different catalysts, such as perovskite-based, phosphorene-based, polymer-based, transition metal-based single atom, blue-titania, carbon-based, Mxene and semiconductor-based catalysts. Subsequent chapters analyze hydrogen production techniques, including electrolysis, photobiological, thermochemical, and biomass gasification methods. After reviewing key hydrogen storage technologies, the book concludes with a summary of the applications of hydrogen in various industry sectors. This book is an essential resource for students, researchers, and engineers interested in renewable energy, hydrogen production, and energy storage. Presents the latest advances in hydrogen generation through solar energy Focuses on three key themes—green hydrogen technologies, solid hydrogen storage, and applications of hydrogen energy Considers the major challenges for the hydrogen economy worldwide

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

Advances in Hydrogen Production, Storage and Distribution reviews recent developments in this key component of the emerging "hydrogen economy," an energy infrastructure based on hydrogen. Since hydrogen can be produced without using fossil fuels, a move to such an economy has the potential to reduce greenhouse gas emissions and improve energy security. However, such a move also requires the advanced production, storage and usage techniques discussed in this book. Part one introduces the fundamentals of hydrogen production, storage, and distribution, including an overview of the development of the necessary infrastructure, an analysis of the potential environmental benefits, and a review of some important hydrogen production technologies in conventional, bio-based, and nuclear power plants. Part two focuses on hydrogen production from renewable resources, and includes chapters outlining the production of hydrogen through water electrolysis, photocatalysis, and bioengineered algae. Finally, part three covers hydrogen production using inorganic membrane reactors, the storage of hydrogen, fuel cell technology, and the potential of hydrogen as a fuel for transportation. Advances in Hydrogen Production, Storage and Distribution provides a detailed overview of the components and challenges of a hydrogen economy. This book is an invaluable resource for research and development professionals in the energy industry, as well as academics with an interest in this important subject. Reviews developments and research in this dynamic area Discusses the challenges of creating an infrastructure to store and distribute hydrogen Reviews the production of hydrogen using electrolysis and photo-catalytic methods

This paper examines the potential of hydrogen fuel for hard-to-decarbonise energy uses, including aviation, shipping and other. But the decarbonisation impact depends on how hydrogen is produced.

Among energy sources, hydrogen gas is clean and renewable and has the potential to solve the growing energy crisis in today's society because of its high-energy density and noncarbon fuel properties. It is also used for many potential applications in nonpolluting vehicles, fuel cells, home heating systems, and aircraft. In addition, using hydrogen as an energy carrier is a long-term option to reduce carbon dioxide emissions worldwide by obtaining high-value hydrocarbons through the hydrogenation of carbon dioxide. This book presents the recent progresses and developments in water-splitting processes as well as other hydrogen generation technologies with challenges and future perspectives from the point of energy sustainability.

Given the backdrop of intense interest and widespread discussion on the prospects of a hydrogen energy economy, this book aims to provide an authoritative and up-to-date scientific account of hydrogen generation using solar energy and renewable sources such as water. While the technological and economic aspects of solar hydrogen generation are evolving, the scientific principles underlying various solar-assisted water splitting schemes already have a firm footing. This book aims to expose a broad-based audience to these principles. This book spans the disciplines of solar energy conversion, electrochemistry, photochemistry, photoelectrochemistry, materials chemistry, device physics/engineering, and biology.
