Chapter 3 - Waste to biohydrogen: progress, challenges, and prospects

Abstract

Waste is produced in the process of people’s lives and production that pollutes the environment. Some of the waste contains a lot of organic matter. Through some treatment methods, this organic matter can be extracted to produce clean renewable energy, such as hydrogen energy. Biohydrogen production technology is a promising method of hydrogen production. The effective treatment of organic waste is the premise of the industrialization of hydrogen production, and optimization of the process and technology of hydrogen production is the basis of the industrialization of hydrogen production. Therefore, it is necessary to have a solid grasp of progress in the research of waste to biohydrogen, a clear understanding of its challenges, and a clear direction of its prospects. This chapter aims to introduce progress in the research, challenges, and the development prospects for biohydrogen production from waste. According to the results, it may be concluded that research in biohydrogen production from waste is still in the primary stages of exploration and faces various problems and challenges. Nevertheless, biohydrogen production technology is one of the best methods for the rational use of waste.
