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

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
