 The excess power generation capacity available in India is nearly 500 billion units/year presently and another 75,000 MW conventional power generating capacity is in pipeline excluding the targeted 175,000 MW renewable power by 2022.The hydrogen fuel generated by 500 billion units of electricity can replace all diesel and petrol consumed by heavy and medium duty vehicles in India completely obviating the need of crude oil imports for internal consumption.Use of hydrogen as fuel to replace jet fuel by the aircraft's is also promising proposition.
