Research Projects

The HABSEB project aims to upgrade biogas, a flammable gas with 50-70 CH4 and 30-50 CO2 produced from anaerobic digestion of various types of biomass, to use as renewable fuel. The project will investigate biohydrogen production from dark fermentation (DF) of biomass substrates, monitor and optimize biological hydrogen-based methanation (BHM), establish the dynamics of microbial communities in both BHM and DF, and connect DF and BHM to develop HABSEB technology for biogas upgrading. The project will also analyze energy, cost-economics, and environmental impact of HABSEB technology. The project will test biomethane in various applications, with a focus on rural areas, to replace natural gas. The project will be divided into four phases: monitoring the BHM technique under various operating conditions and reactor configurations, focusing on biohydrogen production using dark fermentation, and further purifying the enriched biogas using adsorption/absorption technology. The project will result in joint publications, conferences, and practical implementation of the technology in both countries. The proposed in-situ upgradation of biogas enhancing methane content will have high commercial value and reduce costs for further upgradation.
