Its said that the costs involved are higher than other fuels in terms of storage and transportation. Overall the fuel is better and more efficient then the fossil fuels. The transition is indeed underway at an exceptional level. Not explored much, but India has a huge potential in green hydrogen with favourable geographic conditions.
Companies that i came across were RIL, GAIL, NTPC, IOC, etc planning to set up green hydrogen plant.
Green hydrogen is more sustainable than lithium batteries in the long term. But till the time the production for green hydrogen becomes feasible, lithium batteries will lead the way. The Indian govts move to switch to green hydrogen can have a huge pay-off for us, domestically and globally.
