Re: No Sun, No Wind, Now What? Renewable Energy Storage
#22Nuclear energy has so much potential. Pretty sad people are scared of it. It's clean, it's energy dense, and we can make a lot of it. France gets most of it's energy from Nuclear plants.
a) there is a difference between electricity production and energy use. Typically countries don't use electricity for all energy needs. b) are you aware that half of the nuclear fleet in France isn't online? https://www.brusselstimes.com/belgium-news/274261/controlled... > It's clean, it's energy dense, and we can make a lot of it.

Ironically, France has issues now because they spent around 120 billions on renewables with very few results.
Had this money been spent on the nuclear grid, the gris would be in a much better state now.

Nuclear is dead not because people are afraid of it. Nuclear is dead because it is way more expensive than alternatives. Always was, and getting moreso as renewables cost continues on down. In the foreseeable future, nukes will be mothballed long short of their design life just because nobody will want to pay enough for their power to enable continuing to operate them. Geothermal might suffer the same fate. When a nu…
It's only more expensive if you don't factor external costs due to renewables.
At the moment, renewables still can't compete on pricing with 70s nuclear designs...

Nuclear as base load is rather price efficient. And with enough units it can deliver at that price every hour of the year. Not as cheap as renewables, but still very affordable.

120 billion... So around 12 new plants at least? And probably more as they would have not screwed up most of those...

Yes, that's about half of the cost of the current nuclear grid spent for about 7% of the production.

It is sad that proliferation of material for nuclear weapons is that scary. Not that I'm arguing that it isn't. But the nuclear waste that's radioactive for 200,000 years doesn't have to be. Breeder reactors and fuel reprocessing can reduce that to hundreds of years. Yeah that's still longer than a couple human lifetime generations, but nowhere near trying to put up warning signs that will continue to scare away people through the rise and fall of several civiliations.

#28Somewhat disappointing... Would have liked for her to call out NRGV as the actual investment scam it is, rather than just pathetically inadequate. Would have preferred for mineshaft gravity storage to be mentioned, which is not a scam, in place of NRGV. Would have liked for her to cite ammonia along with hydrogen as chemical storage media. And to mention recent, radical improvements in hydrogen electrolysis efficienc…
How can you claim nuclear cannot compete on costs? We have no idea how much any of these things you're talking about will cost, because they either don't exist, exist only in research labs, or have never been deployed at the necessary scale.

Renewables plus storage are incredibly expensive. There is zero grid running on renewables (besides hydro) for base loads today.
You wish renewables plus storage were expensive. But they are, in fact, not.
