The world’s solar capacity reached 1,419 gigawatts in 2023, way beyond any predictions.

@Jonathan Hartley Nope. You need 100% backup(from about 50% of Ren share). Fossil backup.
That's why it's not cheap. and will not be. Never.
#^https://en.wikipedia.org/wiki/Dunkelflaute@martin you might need access to 100% backup while still being able to reduce your need for fossil generated energy by a majority amount - those aren't incompatible.

@dzwiedziu @infobeautiful are you asking about "lobbying" efforts (this would be R 2023/1542 and Digital Battery Passport kicking in next year). The whole regulations only skim non-patentable technologies, like lead-acid batteries. These can be operational for millenia, due to their simple chemistry. The only maintenance that must be done is on-site processing of sulfated battery plates. Something that once upon a time (1950-1990) was being done on the massive scale in Central/East Europe countries. Then lobbied country's legislative can bar mid-sized installations as unable to met the EU demands (tried recently in Poland afair).

So you're saying that to solve energy and heat storage we need sites that will have large amounts of a poisonous, bio-accumulative heavy metal working in an highly hazardous acid, and all that working within daily deep-cycling, on an industrial scale, plus constant industrial-scale recycling, and that it will be cheap and safe?Yeah, no citations (not counting regulation existing alone) means I'll pass.

@TechConnectify has a take on that: https://youtu.be/KtQ9nt2ZeGM

The world’s solar capacity reached 1,419 gigawatts in 2023, way beyond any predictions. 1 gigawatt = power for a medium sized city
@infobeautiful More than enough to power a DeLorean back to the future

@infobeautiful the IEA is famous for denying what cannot be denied until the very last minute.
@infobeautiful the IEA is traditionally very nuclear friendly and of course aware that solar and wind are pushing nuclear from „expensive but with enough subsidies and imperialism it might work“ into „are you ducking nuts?!?“ territory

@Jonathan Hartley
That's true. But it will be expensive. Even with zero price for FV panels.
Or we could have a stable
️ and not have installations with 200% of the required performance, right...

@dzwiedziu @infobeautiful [...] Yes! Almost every point of anti-storage propaganda repeated (the one omitted is about hydrogen being flammable).
Debunking:
1. All components of lead-acid batteries are curently _byproducts_ of other indispensable industries. Lead itself accompanies copper ores. Sulfur is a byproduct of natural gas/oil. Whether either "waste" byproduct ends up in landfills or in batteries matters.
2. Battery plates can be renovated on-site using very simple machines. 50yrs ago operated by humans, now can be entirely autonomous. Very small storages (house) can be renovated by mobile semi-van mounted machine.
3. "Highly hazardous" acid somehow is not that hazardous if used in the car battery. Nor it was when used in warehouse lifters since 1890. -

As for the heat storage: mid-temperature heat accumulator can store around 1MWh per 1 cubic meter of gravel. Insulated by the very same gravel turned into the mineral wool. My house heat accu (I can not build on my own land) is designed to the tune of 7MWh, co it could store heat from 30kW solar installation operating from March to September. This fits into the 6m diameter rotunde. In 2020 was expected to cost around €15000. 4/5 of that the insulation. In non-lobbied regulatory environment this insulation could be made on-site from the gravel (and some amount of aluminium) by simple machine known for two centuries now.

@infobeautiful why were people predicting a /downslope/ for so long, seems like a bizarre forecast. “Oh, solar rates have been climbing modestly for the last few years but I’m sure it’s just a passing fad…”
@bitprophet @infobeautiful there is a whole book by @solar_chase from bloombergNEF on the subject.

It’s almost like there’s an entrenched, wealthy, and powerful special interest group with a vested interest in discouraging investments in solar …
