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.
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.
Here’s some more info on carbon fiber tanks vs COPVs https://www.reddit.com/r/SpaceXLounge/comments/taibc7/in_our_experience_copv_gainpain_flattens_out/
