Abstract
This study explores why large-scale biogas plants are not widely installed in India despite the wealth of biomass resources. The methodology includes an extensive literature review and surveyed biogas experts in different sectors, such as private, public, and academic, to identify and rank key obstacles using the Analytical Hierarchy Process (AHP) and Fuzzy-AHP techniques. Overall, 27 barrier elements were identified across six different categories. As perceived by different experts, except for financial barriers, notable differences were found in the relative importance of other barrier categories. Among the different barriers, competition from other fuels, subsidies, lack of financing mechanisms, and feedstock variation are the most influential. To overcome these challenges and successfully promote the growth of the biogas sector in India, a combination of financial strategies, collaborative efforts, standardized procedures, and comprehensive resource mapping were proposed. These measures can inform effective policy development and contribute to achieving numerous Sustainable Development Goals.
