New Delhi: Indian Railways on Thursday signed a preliminary deal with gas firm GAIL (India) Ltd to use natural gas in some of its operations, part of a drive by the world’s third biggest oil consumer to gradually shift to cleaner fuels.

India is building infrastructure, including pipelines and import facilities, to raise the share of gas in its energy mix to 15% in next few years from the current level of about 6.5%.

Using natural gas will be about 25% cheaper than the alternative fuels used by the railways at workshops and production units, said Ashwani Lohani, chairman of Indian Railways’ board.

He said the company would strive to shift all 54 of its workshops to natural gas by June 2019.

Indian Railways annually consumes about 3 billion litres of diesel, said Chetram, chief administrative officer of Indian Railways Organisation for Alternate fuels.

Only a fraction of that will be replaced by natural gas, he added.

He said Indian Railways can replace 844,027 cubic metres of acetylene, 2.35 million kilograms of liquefied petroleum gas and 140,991 kilograms of cut gases to save 17 crore ($2.4 million) a year.

“The objective of this memorandum of understanding is, on a pan-India basis, wherever we have reach, we will be supplying natural gas to the Indian Railways," said B.C. Tripathi, chairman of GAIL India.
