I wish I got to do fun little projects like this at my job. Anyway, this proof of concept shows that hydrogen would be a great alternative to propane and natural gas for cooking. Hat tip to @hypx@mastodon.social.

Portability is hard for hydrogen since you hadn’t liquify it without huge pressures and cryogenic temps, so you need big tanks. But cooking stoves does seem like a pretty good use case.
I think the experts who believes in this technology know a bit more than you and me who only read a few wiki pages.
If money is going into this, they also have a believable plan. But big oil certainly want you to think otherwise.
That’s an appeal to authority fallacy if I’ve ever seen one.
They’re doing proof of concepts, not mass production. They’re at best answering is it possible, not is it a viable alternative.
Compress it to 10,000psi and it gets portable enough.
As I said, huge pressures. You’ll need super heavy or super exotic tanks.
What’s so exotic about a composite pressure vessel? They’re already used in scuba and paintball.
Scuba tanks only go up to 5.5ksi. I think you’d need more like composite over wrapped pressure vessels (COPVs) for 10ksi. Those are relatively new even in spaceflight. SpaceX discovered some new physics when their AMOS-6 mission exploded on the launch pad in 2016 due to oxygen freezing inside the composite layers.
