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 @[email protected].
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.
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/
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.
Huh? It’s big oil and the like who are pushing hydrogen over electricity.
And the problem with hydrogen is largely to do with the laws of physics, so it’s unlikely to change soon.
I don’t understand this suspicion. It’s easier to burn fossil fuels for electricity than to reform them into hydrogen.
Well yeah but they know their days of selling that are numbered, at least for lots of markets. If they can get people onto hydrogen they’ve got more money coming in for decades.
Their days aren’t numbered until governments actually say so. In the meantime, non-GHG emitting sources supply less than half of the world’s electricity as is, nevermind the hypothetical demand of a predominantly electrified vehicle fleet.
Governments and markets are saying so.
But they can still sell hydrogen, they can’t really sell solar panels. Even encouraging people to keep burning things (like hydrogen) benefits gas since it slows down electric alternatives to gas heating.
They don’t have to sell hydrogen or solar panels. They’ll just keep selling fuel to power plants.
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.
