Comment on Texas Needs Equivalent of 30 Reactors to Meet Data Center Power Demand
sugar_in_your_tea@sh.itjust.works 1 day ago“Baseload” nuclear has the inverse problem of renewables. It needs to sell all of its very expensive power near 24/7.
Excess nuclear production at night recharges batteries for daytime use, reducing the need for battery and solar rollout. Excess solar production during the day recharges batteries for nighttime use, reducing the need for baseload supply. Daytime use is higher than night time use, so this is pretty close to the ideal setup, no?
Use each non-polluting source for what it’s best at. You don’t need any one source to be the primary supplier of electricity, you want a diverse enough set that you get an optimal mix to keep costs and pollution low and reliability high.

Yes, both can charge batteries. Solar charges then at 10x less cost, and combined solar+batteries provides the same total “baseload function” at 2x-4x less cost, and can be up and running in 1 year instead of 10, and expanded the year after that. It’s even a myth that nuclear uses less land. You can use the land under solar, and you don’t need exclusion zones around reactors and uranium mines

It’s lower initial cost, sure, but what about longer term? Surely battery costs add up long term as they need to be expanded and replaced, making nuclear more attractive after 10-20 years.
I’m not an expert here though, I’m merely saying a lot of people would be fine with a higher initial investment if the long term benefits justify it.

No. Nuclear also has fairly high operations/staff costs, and fuel is highly variable and more expensive the more other nuclear plants there are. You mentioned the possibility of charging batteries (Hydrogen also possible) from nuclear, to handle peak day use/transmission, but batteries pair better with solar, and as a total package can serve same “baseload” purpose as nuclear but cheaper. There are no long term benefits to nuclear… economic ones ignoring weapons motivations.

Yeah, I just think of hydrogen as a battery, and it can totally be a closed loop system.
Is that actually true though? As in, if we add up initial installation cost + running cost + replacement cost long term (say, 50 years), are batteries generally cheaper?
If so, then I’d agree. But my understanding is that nuclear gets really competitive the longer it runs.
