Emerging Technologies and Biological Systems for Biogas Upgrading

Emerging Technologies and Biological Systems for Biogas Upgrading systematically summarizes the fundamental principles and the state-of-the-art of biogas cleaning and upgrading technologies, with special emphasis on biological processes for carbon dioxide (CO2), hydrogen sulfide (H2S), siloxane, and hydrocarbon removal. After analyzing the global scenario of biogas production, upgrading and utilization, this book discusses the integration of methanation processes to power-to-gas systems for methane (CH4) production and physiochemical upgrading technologies, such as chemical absorption, water scrubbing, pressure swing adsorption and the use of membranes. It then explores more recent and sustainable upgrading technologies, such as photosynthetic processes using algae, hydrogen-mediated microbial techniques, electrochemical, bioelectrochemical, and cryogenic approaches. H2S removal with biofilters is also covered, as well as removal of siloxanes through polymerization, peroxidation, biological degradation and gas-liquid absorption. The authors also thoroughly consider issues of mass transfer limitation in biomethanation from waste gas, biogas upgrading and life cycle assessment of upgrading technologies, techno-economic aspects, challenges for upscaling, and future trends.Providing specific information on biogas upgrading technology, and focusing on the most recent developments, Emerging Technologies and Biological Systems for Biogas Upgrading is a unique resource for researchers, engineers, and graduate students in the field of biogas production and utilization, including waste-to-energy and power-to-gas. It is also useful for entrepreneurs, consultants, and decision-makers in governmental agencies in the fields of sustainable energy, environmental protection, greenhouse gas emissions and climate change, and strategic planning.

Nabin Aryal is an Associate Professor at the University of South-Eastern Norway (USN), Norway. He received MSc in Environmental Technology and Engineering from Ghent University, Belgium, with an Erasmus Mundus fellowship from European Union and then a PhD. from the Technical University of Denmark (DTU) in Environmental Biotechnology with financial support from Novo Nordisk Foundation, Denmark. Before joining USN, Dr Aryal engaged in joint industrial postdoctoral research at Aarhus University and the Danish Gas Technology Center, Denmark. He has more than a decade of work experience from Norway, Denmark, Belgium, the Czech Republic, India, and Nepal. His current research focuses on microbe-material interaction, biofilm-based bioprocess development, anaerobic technology, biogas upgrading, and carbon dioxide utilization. He has co-authored over 40 scientific publications and edited one book on biogas upgrading that received h-index 15 (>1100 citations; Google Scholar).
