Hydrogen is essential, but we need it for the chemical industry, steelmaking, etc. Using hydrogen as an incredibly expensive and inefficient battery by turning it back into electricity is not the future.
Hydrogen has to be stored at cryogenic temperatures and high pressures to reach any sort of capacity. Desnsity wise your not going to beat cubic kilometers of water halfway up a mountain in cost per kw, even before factoring in the far higher power losses that come with synthesizing or domposing hydrogen.
Yes, that’s the point. The problem of batteries is that you need to mine a vast amount of raw materials for them. So it doesn’t even matter how much “better” they are. It is simply not an answer no matter what.

@zurohki @Hypx Given the ability to build pretty large hydrogen or ammonia tanks, would it scale better than dams or chemistry for week-plus durations?
