All seven of its California stations will close immediately.

You can use electricity on the grid to charge a car. Not sure if you were aware of that. It's going to be a whole lot more efficient at it than hydrogen.

No shit. You know you need a substation to power a supercharger grid...you know how many substations just randomly exist in rural areas to power superchargers? And how expensive they are to build and maintain?

[–] frezik@midwest.social 2 points 9 months ago (1 children)

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

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 2 points 9 months ago (1 children)

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

[–] SupraMario@lemmy.world 1 points 9 months ago (1 children)

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.

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.
