@MattMastodon @BrianSmith950 @Ardubal @Pampa @AlexisFR @Wirrvogel @Sodis There seems to be a lot of uncertainty around the cost of green hydrogen. The first three Google links differ wildly on it.
Natural gas has certainly increased the cost of grey hydrogen lately.
If the problem is the cost of electricity, that's easily solved by producing mainly when there's a surplus of green electricity. However, if the cost is the capital outlay, that's harder. Which is it?
Of course, we can and must require by law that all new capacity be green. Current incentives also include blue, but there is more green hydrogen actually being built.
@MattMastodon @BrianSmith950 @Ardubal @Pampa @AlexisFR @Wirrvogel @Sodis The problem with using it for long term electricity storage is leaks, of course. It's a weak greenhouse gas (sort of).

@MattMastodon @BrianSmith950 @Ardubal @Pampa @AlexisFR @Wirrvogel @Sodis There is commercial production of green hydrogen today, but it requires a subsidy. The cost of grey hydrogen does not reflect the damage it causes.
