Sweden has very little natural gas in its energy mix:

I highly doubt that hydrogen heating was ever considered. It's usually pushed by the gas lobby (since most hydrogen comes from gas), and Sweden doesn't have a strong gas lobby.

The idea was to transition from coal to natural gas while using solar and wind to reduce fuel consumption, thereby significantly reducing CO2 emissions. Any claims of hydrogen being burned were either lies to the public to get the gas plants built despite the non-green optics or lies to investors as part of a fraud scheme.

That was extremely stupid of them then. Hydrogen has been very good at one thing: subsidy extraction. But I don't think it was or ever will be a viable fuel for planetary transportation.

Good context. It's a shame none of these people did high school chemistry.

I do remember there being some news about the steel manf.

I wonder if further advancements in rocketry are adding H2 tech that could help us manage the difficulties of dealing with the stuff. It still only makes sense in very specific circumstances. Like when you need energy in tank form.

But I think battery / biofuel is the future.
