**Guwahati, India** – Scientists at the Indian Institute of Technology Guwahati (IITG) have developed a groundbreaking laboratory-scale process to convert methane and carbon dioxide into a cleaner biofuel, offering a potential solution to both climate change and fossil fuel depletion. The research, led by Professor Debasish Das and Dr. Krishna Kalyani Sahoo, utilizes a special type of methane-eating bacteria, *Methylosinus Trichosporium*, to produce biomethanol.

Unlike traditional chemical methods, this biological process is significantly more energy-efficient, avoids toxic byproducts, and eliminates the need for expensive catalysts. The two-stage process first captures methane to generate bacterial biomass, then uses this biomass to convert carbon dioxide into methanol. Tests blending the resulting biomethanol with diesel fuel showed an impressive 87% reduction in carbon monoxide, hydrocarbons, hydrogen sulfide, and smoke emissions, while also improving fuel consumption and engine performance.

“This is a significant leap toward sustainable energy solutions and climate change mitigation,” said Professor Das. He highlighted the process’s advantages over conventional biofuels, emphasizing that it doesn’t compete with food production as it utilizes greenhouse gases instead of crops. The biomethanol produced can also serve as a precursor for various chemicals, offering potential applications across several industries.

While currently at a five-liter laboratory scale, the researchers believe this biological approach holds immense potential for decarbonizing industries like oil and gas, refineries, and chemical manufacturing. The team’s findings represent a significant advancement in the quest for cleaner, more sustainable energy sources.
