I agree, only green H2 from renewables should be considered together with fuel cells that produce waste heat but also electricity to drive heat pumps or supplement the local grid when renewables are short.

That is a better option for sure. Although storing hydrogen without losing a lot of its energy is difficult. Right now the focus should be on producing green hydrogen for use in fertilizers etc. instead of using dirty hydrogen.

Yes, just replacing dirty hydrogen will take a very long time and effort. Burning green H2 that could replace gray H2 in chemical processes is criminal at this stage.
