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.

Add a hydrogen generator and all you need is water and electricity to make the hydrogen. You don't even have to transport it.

I'd much rather transport a bottle of hydrogen to a cookout than an electrolyzer. What if a power outlet isn't available?

And I’d rather transport a cheap and widely available propane tank instead of an ultra high pressure hydrogen canister that can only be refilled at 3 places in the entire state.

Yes, but imagine a world where propane and other fossil fuels are no longer available. You're going to lug a big battery around for an electric grill instead?

For what it's worth hydrogen stations currently dispense at 10,000psi, which is considered "medium" pressure in the field. "Ultra high" pressure is considered an order of magnitude greater.

Yeah batteries would probably work. A large battery bank can have 1kwh of capacity, and induction stoves are about 1.5kw. Which means you could run a stove for about 40min. You could bring more for longer. I'm sure by the time you can't get propane, batteries will have gotten much better too.

That's a lot of future e-waste to lug around just for cooking.

As opposed to a lot of super compressed gas to haul around? I didn't think this super niche use case justifies a whole different technology.
