And where do they get the hydrogen???

Fossil fuel... But you really have to dig to find where they admit it.
Last time this came up it was buried in the documentation about how wind and solar don't provide enough.

This is exactly what I was thinking.

In all fairness hydrogen is good battery store for green energy too.

it's awful. WTF. Takes huge energy to keep it cryogenically stored.

[–] drmoose@lemmy.world 1 points 9 hours ago

Where are you getting that it needs to be "cryogenically stored"? It's mostly stored as compressed gas.

The main problem with hydrogen is stores only 40% but with green energy surplus and 40% is better than 0% and hydrogen store systems are quite cheap and mature/simple so still relevant in highly developing areas like those of India.

It's still a good battery for these specific niches so I wouldn't discount this as some big oil propaganda

No. No it isn't. That's not how it's made and not how it's used. Its overwhelmingly made by the fossil fuel industry and calling it green in any sense is just greenwashing mostly the worst environmental problem generators the world knows.
