HYDROGEN FUEL CELL FOR VEHICLES - its working, benefits and limitations

India has an ambitious ' Green Hydrogen Mission' - to produce 5 million tonnes of fuel annually from 2030. The project aims to reduce dependence on fossil fuels & avert 50 metric tonnes of GHG emissions.

A great chunk of money in this mission has been devoted to developing electrolysers.

Problems:

-Producing 1 kg of this clean fuel needs 8-9 litres of water.

- India needs to enhance its current electrolyser production capacity.

- Access to Rare earth metals is required to scale up electrolyser production capacity.
