Compressed Biogas (CBG)

This book provides theoretical and practical information on biogas production and upgradation (CBG) in a lucid manner and real-life scenarios. The core topics covered include: (i) introduction to biogas production, cleaning and up-gradation and specifications of biomethane in various countries for different applications; (ii) description of various processes and technologies for the cleaning of biogas; (iii) a detailed information on the technologies for separation of carbon dioxide from biogas to upgrade it to biomethane (CBG), (iv) assessment and comparison of the biogas up-gradation technologies on the basis of various techno-economic factors, (v) design and development of water scrubbing technology and (vi) future prospects of decentralized biogas up-gradation and bottling technology. CBG is a growing field for mitigating climate change, waste management, and disposal. This book provides information on how the biogas up-gradation sector is developing and how it could harness its potential in a decentralised manner. A broad description of technological innovations and developments in the sector has been provided. This book will be of use to students, researchers, professionals, entrepreneurs, municipalities, nodal agencies of state and central governments, CBG Plant owners & operators, etc. It can also be used as a text for professional training, skill development and capacity building for stakeholders.

Prof. Virendra Kumar Vijay is a professor at the Centre for Rural Development and Technology, Indian Institute of Technology Delhi, and is an acclaimed and internationally acknowledged scientist in rural technologies, transforming the higher education process, biogas enrichment & bottling technology for vehicular application (Compressed Biogas -CBG), bioenergy, etc. He has 37 years of Teaching, Research, and Outreach experience in renewable energy, rural development and technologies, biogas generation, enrichment & bottling technology for vehicular application, cow-based economy, etc., influencing several national policies and programs. Prof. Vijay is the national coordinator of Unnat Bharat Abhiyan – a flagship program of the Ministry of Education, GoI - transforming Students and faculty of the Higher Educational Institute of the country for inclusive education, and coordinator of the Biogas Development and Training Centre (BDTC), Ministry of New and Renewable Energy, GoI. He has been known for designing and developing small-scale biogas purification CBG and bottling technology for vehicular applications in India since 2002. IIT Delhi patented the water scrubbing technology in 2006 and licensed it to more than 11 industries, many Gaushalas, and young entrepreneurs for field implementation. IIT Delhi has been operating India’s first and only biogas car for the last 15 years, which has crossed more than 1,40,000 km run on biogas. Based on the data on the performance of the engine, emissions, derating, and degradation on the use of upgraded biogas in the car and its experience, the Bureau of Indian Standards formulated the IS 16087 Biomethane standard in India in 2013 ( Presently used for CBG) . He has also been the General Secretary of Biogas Forum India, A society promoting biogas and biofertilizers in India since 2011. Prof. Vijay has over 240 publications in journals and conferences, eight books, and one lab manual to his credit. He has also delivered over 250 invited lectu

Sharang Dev Sharma is a PhD research scholar at the Centre for Rural Development and Technology (CRDT) at the Indian Institute of Technology Delhi. Sharang’s PhD research currently focuses on optimizing the site suitability of compressed biogas (CBG) plants using Geographic Information Systems (GIS) and multi-criteria analysis tools. Sharang completed his Bachelor of Engineering in Electrical and Electronics Engineering. He further advanced his expertise by earning a Master of Engineering in Information and Communication Technologies from the Asian Institute of Technology in Bangkok, Thailand. His master’s thesis demonstrated his ability to integrate advanced analytical tools with sustainable energy solutions in the solar energy domain. Before starting his doctoral studies, Sharang gained substantial industry experience as a Planning Manager for the Seagate Technologies External HDD project for Asia at Cal-Comp Electronics Public Company Thailand Limited, part of the New Kinpo Group in Taiwan.

Dr. Vandit Vijay is working as a “Scientist C” at the Sardar Swaran Singh National Institute of Bioenergy, Kapurthala (An autonomous institute of the Ministry of New and Renewable Energy, Govt. of India). He worked as an outstation postdoctoral research scientist with TU Delft, Netherlands, from 2019 to 2021 in their Negative Emissions Program. He completed his PhD from IIT Delhi from 2014 to 2019 on self-reliant energy systems for villages using locally available resources - ग्राम ऊर्जा स्वराज model. His major work areas at SSS-NIBE include biomass resource assessment and mapping, development of the National Biomass Atlas of India, biomass supply chains, and policies. His research also focuses on biomass utilisation through different conversion pathways for energy sufficiency in rural areas and carbon neutrality. He has experience in biogas and biodiesel production from different feedstocks and their utilisation for various energy applications, including biofuel-based IC Engines and sustainability analysis of bioenergy systems. He has more than 20 authored/co-authored publications. He has a B.Tech degree in Mechanical Engineering (2008 - 2012), and before joining the PhD program, he worked at the Society of Indian Automobile Manufacturers from 2013 to 2014.

Dr. Rahul Jain is an alumnus of the Indian Institute of Technology (IIT), Delhi.
