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.
Fun project! But replacing gas with hydrogen seems really tricky. Hydrogen is much harder to transport without leaks because it’s such a tiny molecule. Electric seems better than trying to still burn hydrogen.
The best way to store and transport hydrogen is to combine it with carbon so that it becomes a convenient liquid fuel. As a bonus, then you don’t even need fuel cells to make electricity from it, but can instead simply burn it in something called an “internal combustion engine”
Nah, combustion engine is just one step up from the steam engine, such a wasteful technology, should long be in a museum.
First thing i think about in using a hydrogen-carbon fuel, is fuel cell (no better word for “Brennstoffzelle”?) to create electricity. Next up a steam turbine.
Tons of experts believe the only way hydrogen based transportation makes sense is by using it to fuel heavy transport right at the source instead of trying to transport it via pipeline.
Electric is far more efficient too, thus cheaper. Electricity you can transit over distance over wire and generate however you like. We’ve done it a long time, far and wide.
Turning electricity into hydrogen, distributing it, and then turning it back into electricity to move a vehicle, is so wasteful/expensive.
Just use a big battery.
For some applications like spacecraft where weight is critical, it does make sense to use hydrogen fuel cells as a battery. But usually it doesn’t make sense.
As Toyota has demonstrated (and speaking from my own experience), it’s not that tricky. As for cooking with the stuff, sometimes you just need portability and/or a flame. Electric is a poor choice in those cases.
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.
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.
Just need to waste a ton of energy extracting it then liquifying it then hoping that transport doesn’t face any issues (and I mean, considering our track record with petrol which doesn’t corrode everything it touches I sure as hell wouldn’t worry about it [/s if it wasn’t clear]) and then fill up your personal car that could have simply been powered by electricity from the beginning…
Also, ever heard of energy density? Because hydrogen won’t win prizes on that front!
Wait wait wait, you’re telling me that taking electricity, sending it along wires, generating hydrogen with it via hydrolysis, packaging it, compressing it to an extreme degree, physically transporting it, putting it in pumps, pumping it into your car, then doing reverse hydrolysis to charge a battery that then powers an electric motor…
Is less efficient than sending electricity along some wires to your car battery, to then drive an electric motor?
I’m shocked!
