The sixth volume of this handbook provides an overview of the research on the country-based experience of bioethanol fuels at large, Chinese, US, and European experience of bioethanol fuels, production of bioethanol fuel-based biohydrogen fuels for fuel cells, bioethanol fuel cells, and bioethanol fuel-based biochemicals with a collection of 17 chapters. Thus, it complements the fifth volume of this handbook.

Hence, the sixth volume indicates that the research on the evaluation and utilization of bioethanol fuels has intensified in recent years to become a major part of the bioenergy and biofuels research together primarily with biodiesel, biohydrogen, and biogas research as a sustainable alternative to crude oil-based gasoline and petrodiesel fuels as well as natural gas and syngas.

This book is intended for students, researchers, engineers, policy makers, economist, business managers, and social scientists, working on the production, utilization and evaluation of bioethanol fuels.

Ozcan Konur has interdisciplinary research interests and has published primarily in the areas of bioenergy and biofuels, algal bioenergy and biofuels, nanoenergy and nanofuels, nanobiomedicine, algal biomedicine, disability studies, higher education, biodiesel fuels, algal biomass, lignocellulosic biomass, scientometrics, and bioethanol fuels. He has edited a book titled Bioenergy and Biofuels (CRC Press, 2018), a handbook titled Handbook of Algal Science, Technology, and Medicine (Elsevier, 2020), and a handbook titled Handbook of Biodiesel and Petrodiesel Fuels: Science, Technology, Health, and Environment (CRC Press, 2021) in three volumes.
