Biohydrogen Book Excerpt:

The world’s energy markets rely heavily on fossil fuels (such as coal, petroleum, and natural gases). However, due to increasing energy demands, depleting reserves of fossil fuels, and increasing negative effects on the environment (e.g., global warming and climate changes), as well as growing political instability in oil-producing nations, the world is facing a major energy threat that needs to be solved by virtue of alternative energy sources utilizing renewable resources. The only natural, renewable carbon resource known with large enough capacity to substitute for fossil fuels is biomass. Thus, energy from biomass is considered to be one of the most promising alternatives to fossil fuels. Among the existing biomass energy/biofuels, biohydrogen has received considerable attention as it is clean, renewable, has a high energy content, and does not contribute to the greenhouse effect. Biomass is projected as a virtually eternal raw material for hydrogen (H2) production; however, the main bottleneck is the low hydrogen yield arising from poor efficiency on direct microbial assimilation of biomass. Therefore, technologies leading to more efficient and commercially viable production of biohydrogen from biomass and other renewable resources are urgently demanded. This chapter sheds light on some of the practical approaches of fermentative H2-generating processes utilizing a variety of biomass and renewable resources as substrate. This chapter also emphasizes biohydrogen production technology that could maximize hydrogen yield by designing efficient bioprocess integration and energy and waste minimization. Improving the hydrolysis of biomass has been recognized as a key step toward biohydrogen production. Considerable research efforts made on improving the pretreatment and hydrolysis of biomass materials are also addressed. Emphasis is given to discussion of the process based on important operating factors involved and to delineation of some of the process limitations. The aim of this chapter is to provide rapidly expanding information on biohydrogen production from renewable resources and to offer clues and possibilities for enhancing the performance of natural waste utilization and dark fermentative hydrogen production to resolve issues related to food security, climate change, energy security, and clean development in the future.

This book examines a broad range of advances in hydrogen energy and alternative fuel developments and their role in the energy transition. The respective contributions were presented at the International Symposium on Sustainable Hydrogen, held in Algiers, Algeria on November 27-28, 2019. The transition from non-renewable polluting energy to sustainable green energy requires not only new energy sources but also new storage techniques and smart energy management. This situation has sparked renewed interest in hydrogen and alternative fuels, as they could help meet these needs. Indeed, hydrogen can not only be used as a clean energy vector or as an alternative fuel, but also as a storage medium or as an intermediary that enables improved energy management. This text offers a valuable reference guide for those working in the professional energy sector, as well as for students and instructors in academia who want to learn about the state of the art and future directions in the fields of hydrogen energy, alternative fuels and sustainable energy development.

Renewable Hydrogen Book Excerpt:

Hydrogen has recently become a popular topic and is often described as the missing link to a successful green energy transition. However, hydrogen can only contribute to a carbon-free future if it is produced from renewable energy. The ability to produce renewable hydrogen is linked to the renewable energy production capacity, which is itself conditioned by the underpinning renewable energy policies. This publication offers a review and an analysis of the renewable energy and hydrogen policies of five countries of the APAC markets: Australia, China, Japan, South-Korea and Taiwan. The review is complemented by interviews of renewable energy policy experts, renewable energy project developers and potential renewable hydrogen off-takers. Altogether, the policies analysis and experts’ inputs provide a comprehensive overview of the status, drivers, limitations, and recommendations for the use of renewable hydrogen as a solution for deep decarbonization. Finally, the author proposes a method to assess the potential of renewable hydrogen to decarbonize hard-to-abate industries (ammonia, methanol, oil refining and steel manufacturing) based on existing renewable energy policies.
