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

💯
The same about the grid. If in region A is constantly produced more electricity than in B, why not create a better grid spread best across countries (here: whole EU)?

It's a bit of a niche thing, because not every company can be disconnected at a whim, but it is an option for low production times.

on the other end of things, if the price companies pay is more volatile than that for individuals/families, some industries are encouraged to plan their most energy intensive activities for the times when energy is less expensive.

Both are things that are being done *now*, not new ideas, we only need to have more of them.

It is demoed. What is missing is commercial scaling and size scaling. Some way of chemical conversion might be inevitable. But there might be some issues with continuity of chemical processes, that might make it difficult to switch/scale that "on demand" when there is excess energy. There are still challenging issues to solve. Nevertheless building up renewables is the way to go.

But like you said, there are barely any demo projects anywhere, this is unproven

See here:

Mikel - Covivienda rural Bioketa (@mikels@masto.es)

@GuillaumeRossolini@infosec.exchange I was thinking about the low tech version, using the mass of the underground of a house to store the heat in the summer and reduce or eliminate heating expense in winter. Heat captured circulating outdoor air, with solar colectors, from excessively warm interior air, below roof air, photovoltaic panel refrigerating air... Do you think that this doesn't "work"?

Seasonal storage is not yet solved. Heat solutions start working, but more as one-off prototypes. No proven turnkey solutions yet.

Flow batteries have unsolved issues with charge loss - not ready yet. For the time being, storage via heat seems to be a good bet.

There's only one reason to promote oil and curb the renewable development - to make every last dollar possible from petroleum products. Given that premise, nothing should be surprising.

Reinald Kirchner (@Reinald@nrw.social)

@passwordsarehard4@mastodon.social @jwildeboer@social.wildeboer.net @openrisk@mastodon.social local heat storage seems to be more feasible than global water pumping. https://www.review-energy.com/almacenamiento/finland-builds-the-world-s-largest-seasonal-thermal-energy-storage-facility There are other concepts with temperatures up to several 100 (500? 600?) °C as well heating up sand oder ceramic rubble.

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.

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.

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

All batteries degrade over useage and time, depending on cycles & discharge depth.

  • Also most 's batteries get "upcycled" beyond their usefulness in battery storage systems, because there the loss of capacity is negligible when adjusted for price & volumetric capacity of competing cell types or buying new ones.

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.

The UK actually favours adding battery storage because you can profit from arbitrage on an industrial scale (and we've had people doing that with pumped storage even before batteries were a meaningful thing). The more we get negative prices the more the "store it and sell it at peak" people make.

Where it all comes undone here is a lot of our wind generation is one end, and industry the other (due to a failure of energy pricing models)
