Agreed, but that's a future issue and probably a ways off. The US just loaned a company half a billion dollars to use renewable hydrogen as seasonal storage:

But in reality, the economics only check out if we get to the "electricity is virtually free" stage, and here's why.
1) We need a few terawatts of new electricity generation to help electrify everything, so any new generation is just going to help try and keep up
2) We need renewable generation to replace current emitting generation
3) Any hydrogen made will be orders of magnitude more valuable to replace the current hydrogen used for fertilizer
