I think the focus should be on seasonal storage and that isn't a fully solved problem. But there are lots of ways to do it that aren't economically competitive yet. But maybe a few of them could easily be competitive if they just picked up some momentum for popularity? It's weird to me that when I search for "hydrogen storage" I get a bunch of results about cars. The biggest challenge for hydrogen seems like safety, and that is a much larger concern for a vehicle in my mind. Whereas I assume you should be able to bury hydrogen tanks for seasonal energy storage and those would be relatively safe. Especially when compared to hydrogen on vehicles zipping around. There are other possibilities for renewable seasonal energy storage. Such as biofuels from algae or maybe vegetables. Ammonia is a possibility. Compressed biogas might help meet seasonal energy needs. Long-term high density batteries would be great. It sounds like this is more hypothetical though at this point?
