Pursuant to the Fuel Policy of 1974, CIL also started the construction of India's First Low Temperature Carbonisation Plant at Dankuni in the late 1970s. It was renamed as Dankuni Coal Complex, and is one of the only operational Coal gas plant of this kind in the world. Dankuni Coal Complex has been incurring heavy loss due to the Greater Calcutta Gas Supply Company (formerly known as Oriental Gas Co.) giving non-remunerative price and fixing them unilaterally. Coal India is planning to venture into Coal-to-Methanol technology at the existing Plant.
