When renewables flood the grid with more electricity than is needed at that moment, we don’t say „How wonderful!

@kkarhan Whch is exactly what the research I linked to shows. Batteries degrade, but the rate of decay is lower than most expected. Fast charging raises the rate of decay, but not as severe as many have feared. A typical EV battery will outlast the car it was built into, leading to the secondary market you mentioned. @etchedpixels @ammdias @eoinho
@jwildeboer @kkarhan @etchedpixels @eoinho
Also, for most people -- who only commute daily to work --, fast charging is mostly unnecessary. The car could be slow charging when parked at work (or in the parking lot where it awaits the return of its owner) **and** at night, at home.

When renewables flood the grid with more electricity than is needed at that moment, we don’t say „How wonderful! Let’s find ways to store that excess electricity so we can share it back to the grid when needed.“ Instead we sing the song of fossil fuel capitalism that claims this is a BAD thing and we need to shut down the renewable plants so The Grid can keep on working based on scarcity and rent seeking. It's like we all have been brainwashed by the grid operators and the fossile fuel industry.
@jwildeboer of course in reality this does happen, but it's also a matter of where your generation and storage are. You can't absorb excess supply from Scottish wind farms with EVs in London, for example.
Grids are definitely getting smarter, but maintaining grid stability with additional renewables and increased electrification is neither trivially easy nor cheap.

@jwildeboer Maybe use the excess to crack water into hydrogen for fuel cell vehicles.
@timjclevenger Hydrogen powered vehicles are barely a thing, but we need to generate it anyway to produce essential stuff like GHG-free steel and fertilizer. It makes more sense to do that than to pursue buy-low-sell-high battery storage schemes. #hydrogen

@OneInterestingFact @jwildeboer @openrisk yes, sorry, it is sodium in english language.
Cobalt free cell cemistry is available.
Again: responsible mining is an issue. We always can do better. The Lithium mining is nevertheless WAY less damaging for nature as oil business is and has been.
Industry scale batteries are done regulary, BMW has a factory with windturbines with battery backup. California has Megawatts capacity to stabilize the network. There are loads of examples.
@Reinald @OneInterestingFact @jwildeboer @openrisk my understanding about grid scale batteries was that they were only good for the short term
As in: grid balancing, best case scenario day/night load shifting?

Mine too - storing PWh to use in 6 months time is way beyond the scale of any tech I'm aware of. -

@simo5 France demands solar panels to cover any parking site with more than 80 parking spaces. EPBD (Energy Performance of Buildings Directive) demands solar design as part of the permit process for new building. Things are changing. https://energy.ec.europa.eu/topics/energy-efficiency/energy-performance-buildings/energy-performance-buildings-directive/solar-energy-buildings_en
@jwildeboer they aren’t rushing to comply, I’m telling you
