That’s not at all what MIT is talking about here. This goes into detail around the challenges tied in rolling out grid scale solar in a way that aligns with supply and demand curves, and how to make sure we’re able to capture overproduction so that we can use it when not enough is being produced. It’s a complex shift to work out in our over 100+ year grid production structure, and has been an ongoing discussion across the energy sector. But you know…memes and shit.

You’re not saying anything contradictory to the criticism, You’re saying the exact same shit with a more expensive vocabulary. I’m also very educated. I also agree the sun is Monty Burns greatest enemy for giving out free light.

Clearly not. The point is that grid scale deployment is not easy. It’s an important discussion to do it right. The criticism is genuinely stupid and just spotlights people who clearly don’t understand how any of this stuff works or what the article is even talking about. You can’t just slap solar panels everywhere and call it a day.

Grid scale redundancies are important. Managing load is important. Energy storage is important. Scaling up renewables and scaling down conventional generation is important. Ensuring those who cannot afford their own BTM generation can access affordable electricity is important. That’s entirely what this conversation is about.

of course it’s a furry shitposting about it.

They aren’t wrong though, storage technology is only starting to come to market in significant enough capacity to be beneficial.

And for storage plants to be financially viable energy costs during the day need to be really cheap, so they can raise them at night and make a significant enough profit to break even.

Solar generation is kinda saving our asses here in Ukraine though, and was even more in the summer. So I guess all you need for solar to be viable is to have most of your other power sources to get bombed

this is actually something that still fascinates me. The fact that i can just buy a market accessible product, point it towards the sun, and i just get electricity is fucking insane to me.

We truly live in the best timeline.

2 giant lakes. 1 uphill from the other, or one underground. When there’s excess energy you pump water uphill. When you need more you let it back down

yeah, good luck with that one though. it tends to be ecologically problematic, and very, very hard to find places good for this. It has happened, but you can’t just build these things as demand desires.

This is why battery based and thermal based energy storage is taking quite the aggressive focus on research and development right now. Batteries are more of a side effect, and very easily accessible, and thermal storage is probably a lot less popular than it should be.

Generally you can do a similar thing with traditional hydro anyway, plus it produces a base level of power anyway.

You’re telling me we can’t dig big holes and use them? What about using old mines and quarries?

Is it a problem that they can’t find anything, or just that it would be a bit expensive and they would rather use batteries as an excuse to keep using oil?

How efficient is making hydrogen? If you don’t need a huge facility, it might be easier to just store it that way, so you don’t need giant lakes everywhere.

ok so funny problem, storing hydrogen is currently the next nobel prize. And uh, generating it while theoretically easy, is very power hungry. (less of a problem here though tbf with cheap solar power)

Also producing power from hydrogen is more complicated than you would think. You could do a hydrogen fuel cell, or possibly burn it directly, but since hydrogen tends to sort be very spicy, it’s a little hard sometimes.

Less efficient than pumped hydro. Appears to be about 40% for green hydrogen in the round trip vs 80% for pumped hydro with a quick google search.
