Limitless ‘white’ hydrogen under our feet may soon shatter all energy assumptions::undefined

Pretty hypetrain article without much to back it up. No commercial drilling potential sites found yet. Sounds like someone needs investor money.

The USGS has a much better article.

It does sound promising, but it looks like there is a fair amount of work to make it economically viable.

Thanks for this.

Hydrogen is a pretty complicated gas to deal with. The flame is nearly invisible in daylight meaning you could be standing in a Hydrogen fire and only tell because your skin is burning off. The molecule is so small that its hard to contain it because seals leak. Storage of hydrogen is also a problem. The density is also very very low in both gaseous and cryogenic liquid form which means you have to have very large containers compared to most other fuels.

The article proposes to graduate hydrogen to a utility grade fuel, which isn't impossible, its just really really hard, and other alternatives are much easier to accomplish the same goal.

One approach may be to located hydrogen combustion or hydrogen fuel cells very close to the point of extraction turning it into electricity as soon as possible. That would bypass most of the storage challenges at least. However, this idea comes with its own challenges as hydrogen extraction points may not be near utility grade power lines for transport of the electricity produced.

You make some interesting points. Would you happen to know if it would be possible to add something to it to make it more visible? Kinda like they add that smelly thing to gas.

Everytime I read about hydrogen being the future I get the feeling of oil lobby selling the next "oil" because thats all they understand. Hydrogen has a future where its energy to weight ratio counts and that is aviation fuel. For now.

It annoys me that the meme's quote is wrong. It's "You keep using that word. I do not think it means what you think it means".

[–] soloner@lemmy.world 12 points 2 years ago (2 children)

The quote is totally messed up for sure. What annoys me as well is that image is not even from that scene or the same person. Doesn't it come from the "inconceivable" poison cup scene?

[–] A_A@lemmy.world 8 points 2 years ago (1 children)

I think the scene is when Wesley's sailboat is catching up on Vidzini's boat and the Giant corrects Vidzini who repeated that yes! ... "inconceivable"

[–] themeatbridge@lemmy.world 2 points 2 years ago

Correct, but it's when Wesley is climbing the rope and they are at the top looking down at him.

Well that was a shit read, asks for a subscription 2.5 sentences in

Hydrogen is going to be abused to white wash fossils, no doubt. It will also keep consumers dependent on gas station distribution. Certain types of companies like both of these things very much.

I don't believe the prices presented in the article. P2X will eventually be able to produce much cheaper green hydrogen than the costs of drilling for white hydrogen. There really isn't a limit to how cheap it can get.

White hydrogen is fine to replace the production of gray hydrogen right now, but I doubt it will continue to be the cheapest method in just a few years.

Definitely seems like a real thing that could be pretty good for the future, here are some other articles from slightly better places:
