      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

        Containment of gaseous hydrogen is problematic because H2’s molecular size is tiny, so it seeps through gaps that would contain other gases. So you need an especially robust container. It’s also highly reactive.

        No idea what your 40% comment was about, it’s incomprehensible.

        They’re the most powerful force pushing hydrogen, so it’d be entirely reasonable to at least consider the possibility.
