IIT Guwahati develops method to convert methane and carbon dioxide into biofuel using bacteria
biofuels using methanotrophic bacteria.
This innovative approach represents a significant leap toward sustainable energy solutions and climate change mitigation.
The research, co-authored by Prof. Debasish Das and Dr. Krishna Kalyani Sahoo, Department of Biosciences and Bioengineering, IIT Guwahati, has been published in Fuel, a leading journal by Elsevier. The study addresses two pressing global challenges: the harmful environmental impact of greenhouse gases and the depletion of fossil fuel reserves.
Methane, a greenhouse gas that is 27-30 times more potent than carbon dioxide, is a significant contributor to global warming. While turning methane and carbon dioxide into liquid fuels can reduce emissions and provide renewable energy, existing chemical methods are energy-intensive, expensive, and produce toxic by-products, limiting their scalability.
IIT Guwahati team has developed a fully biological process that uses Methylosinus trichosporium, a type of methanotrophic bacteria, to convert methane and carbon dioxide into bio-methanol under mild operating conditions. Unlike traditional chemical methods, this process eliminates the need for expensive catalysts, avoids toxic by-products, and operates in a more energy-efficient manner.
