Storage is not just 'a problem', it doesn't exist and won't for many many decades.
replyThe planned solution is hydrogen power plants, but no one wants to build them because the infrastructure, including electrolysers, is way too economically unfeasible.
Therefore, Germany is and will continue to be dependent on coal and gas, as these are the main producers every night. That's your 'grid backup fee' for you.
Long term storage is a problem. Nightly will be solved soon by batteries. California is well on the way, down to 25% fossil in 2025 from 45% in 2022, due to batteries. And they just keep getting built. Australia is on the same track.
replyIf we have to burn some gas to cover the occasional long term weather issue, I’m ok with that , if we’re at 90+% decarbonized at that point it’s still a huge win.
May be base-load is not the best term but in case if batteries and other storages will run out during long cloudy stretch with weak winds nuclear will at least allow to power critical infrastructure. It’s bad that some consumers will loose power but less bad than total apocalypses when the storage is empty and you have no unintermittent power source in the grid.
replyfor the foreseeable future that weather-anomoly backup role is going to be filled by gas. Spins up very fast, nearly zero marginal cost while sitting idle. And yes, it creates emissions, but if you're only using it for rare weather events, you're probably talking >5% of the supply annual total that produces emissions. Which is fine.
