There are downsides to nuclear these days. Incredibly high cost with a massive delay before they're functioning. Solar + wind + pumped hydro + district heating is where it's at in 2024.

[-] ByteJunk@lemmy.world 40 points 3 days ago

This.

Also, tie together more countries' power grids to even out production and demand of renewables, and reduce the need for other backup sources.

For a fraction of the cost of nuclear, increase the storage capacity as well. We've had days where the price per MWh was negative in many hours, because of excess production.

The barriers to carbon free energy aren't technical, they're purely political.

Yeah, back in 2010 and before nuclear was the way to go but with the incredible advancements in solar and wind it's no longer the best option.

Still shame on Germany for decommissioning nuclear reactors and deciding to build Nordstream 2 and burn coal as a replacement.

I haven't heard of any advancement that makes solar generate energy when the sun doesn't shine and wind generate energy when the wind isn't blowing.

The wind is always blowing somewhere and overproduction is cheaper than batteries

You can't overproduce electricity. You have to match the load.

[-] kaffiene@lemmy.world 4 points 2 days ago

I know. There are many solutions to this

[-] fellowmortal@lemmy.dbzer0.com 1 points 2 days ago

No, there is pumped storage. Honestly, despite the plethora of start-ups claiming to have a solution (sodium batteries, molten-salt, etc) The only really proven way to store electricity for later is pumped storage, but that relies on geography (hills) which not everyone has. Batteries are great for phones, and cars but they simply don't scale to countries.

California is doing pretty good with their battery storage. And if all the electric car batteries get old we can use them as stationary grid storage.

[-] fellowmortal@lemmy.dbzer0.com 2 points 2 days ago* (last edited 2 days ago)

That is actually very impressive. Thanks! I remain a bit skeptical as its only 1/5th of what they need and it's only one region of one (rich) country. Still, 10GW of lithium battery would be one hell of a fire ;-)

South Australia implemented a 100mw battery for their power system in 2016

This is wrong. Right now, europe is experiencing high pressure and doesn't have any wind. Check this out its map that shows you how much wind is being produced right now! Can you provide a source that says " the wind is always blowing somewhere" or is it just a platitude?

[-] steuls@sh.itjust.works 0 points 2 days ago

Overproduction is how you get blackouts from damaging the grid

[-] uis@lemm.ee 2 points 2 days ago

Lol, just dump energy into resistors. Or desync two generators.

[-] kaffiene@lemmy.world 2 points 2 days ago

Or convert excess to hydrogen and provide resilience, or have arrangements for industry to consume the excess. Or ramp down your generation at those times. Or shift excess to neighbouring grids.

[-] PeriodicallyPedantic@lemmy.ca 5 points 3 days ago

You haven't heard of any advancements in energy storage at all?

Not that we need them, the best energy storage is old AF and excellent

[-] oo1@lemmings.world 4 points 3 days ago

it has got cheaper, but it has to get cheap enough that you can buy enough batteries with the difference. I'm not sure it has become that cheap. Maybe these sodium battery things will get developed.

[-] partizan@lemm.ee 2 points 2 days ago

You probably also didnt heard about Thorium based molten salt reactors, they are much safer than conventional nuclear, also cheaper, and you can have a 50MW installation in space not much larger than a shipping container. A 50MW solar installation is close to 1km2 and thats without any storage included. It even can be modified to run on spent fuel of conventional nuclear power plants.

SMRs are DOA. They have been “the next big thing” for decades now. They need to shit or get off the pot.

[-] sandbox@lemmy.world 1 points 2 days ago

No industry has quite so much vaporware technology as nuclear power. Any idiot can promise and never deliver. Look at Elon Musk.
