Underground coal gasification (UCG) requires less surface area than traditional coal mining, and therefore represents a potential method to extract energy from India's deep and isolated coal and lignite deposits. If UCG technology is perfected, it could supplement the country's underground coal mining and help address its energy security. It would also strengthen the national policy for the development of sustainable energy resources based on clean coal technologies, such as coalbed methane (CBM), coal mine methane (CMM) and UCG.
