And hydrogen won’t get you there. It’s much easier to build a substation than the new infrastructure for hydrogen.

SupraMario@lemmy.world · 9 months ago

Lol no it is not, do you know what goes into building a substation? They’re expensive and require a lot of upkeep.

frezik@midwest.social · 9 months ago

And so does your idea; you just haven’t thought it through.

SupraMario@lemmy.world · 9 months ago

A solar hydrogen station cost no where near the amount putting in a substation does. I don’t even know where you came up with the idea that it does.

Dude, you don’t even have a good grasp of how much hydrogen you could make from the atmosphere. Nobody is advocating for doing it that way because it’s too much effort for so little gain. I’m not going to take your word on much else.

Yep, totally no one is doing it… it’s not being researched or anything, cause it’s not worth it. Yep, miles and miles of over head wires and substations all over the place it the way to go. No other alternative.

There are very few details on how much they’ve actually generated on any of these. The MIT one doesn’t specify how it’s getting the original water at all.

The IEEE one does actually list it out:

Researchers have built a kilowatt-scale pilot plant that can produce both green hydrogen and heat using solar energy. The solar-to-hydrogen plant is the largest constructed to date, and produces about half a kilogram of hydrogen in 8 hours, which amounts to a little over 2 kilowatts of equivalent output power.

Yeah, that’s about what I’d expect. You are not going to power cars with this.

The one in the Guardian article seems to be targeting it a as a replacement for natural gas in home heating and cooking, which is a maybe.
