Gregory Barber, "Big Batteries Are Booming. So Are Fears They'll Catch Fire" https://www.wired.com/story/big-grid-batteries-are-booming-so-are-fears-fire/
« But grid batteries do have their own risks, which some experts say should be better explained to would-be neighbors. Guillermo Rein, a professor of fire science at Imperial College London, says that the industry has done an excellent job making fires rare despite the inherent volatility of lithium-ion technology. But safety measures are still evolving, he adds, and there are significant gaps in our understanding of how to prevent and lessen the impact of the most catastrophic blazes. “We’re playing catch-up,” he says. “The risk is unknown, and it has to be measured.”
SPARKS, ARCS, AND flames are a risk in any electrical system. When they occur in or around a battery, the outcome can be disastrous. When flames warm a battery cell, one of the repeating components of a larger battery, beyond a certain temperature, a chemical reaction begins that produces more heat, triggering the same process in neighboring cells. Thermal runaway can take off in just milliseconds, before smoke or heat can be detected by an alarm system. The fire spreads first within a cluster of surrounding cells that share electronics, known as a module, and then onto others, until a whole rack of batteries is ablaze.
The first layer of fire safety is preventing that initial spark from happening. Most fire testing involves ferreting out faults in individual battery cells—something the industry, which makes millions of those cells each year for all kinds of energy applications, does well, explains Rein. But as they are packed into larger groups for grid-scale systems, testing becomes more complex, and the pathways to ignition multiply: coolant leaks, shorting electronics, faulty installation. Not every pathway is reproducible in the lab, says Rein, who authored a 2020 review of battery safety standards, which he describes as “chaotic.” »

Batteries are prone to ignite and incinerate. Are there any studies on the insurance risks of large scale storage batteries necessary for the back-up of renewable energy? As they so essential for grid stability, can they be insured at all? How does that impact electricity prices?

The #EU decides to end glued #batteries - we think this is good and welcome the progress, because at #TUXEDO there have NEVER been glued in batteries!

Meanwhile, in battery news...
Researchers at Vienna University of Technology (TU Wien) have developed an oxygen-ion battery with a storage capacity that doesn't decrease over time, leading to an extremely long lifespan compared to other batteries.
This battery can be produced without rare metals and could be used for in large energy storage systems, e.g., to store electrical energy from renewable sources.

Over in the Mastodon-network (a silo of its own), people keep doing the self-introduction thing. I find this idea rather befuddling, esp. when it comes to sharing personal info which we learnt we shouldn't do on the web.
I think you can learn more about a person when you listen to her tone of voice, her manners, and only to some extent via her interests. With regard to the latter, an annotated list of my tags may suffice.
#batteries (although in the context of infrastructure, energy, climate, less as hardware or essential building blocks but as objects on which people put their misguided hopes on)
#counterculture (I went along with it for many years, now I primarily think about its negative impacts; historical interest)
#drought (is more than "heat" a concern to me)
#ecocolonialism (from the perspective of how Greens and Progressives offset environmental costs on poor nations when trying to jump-start their green economies)
#energy (broad category, includes "renewables", "nuclear", often "infrasturcture")
#federation (how its technical aspects create the conversations-based foundation of the Fediverse)
#fediverse (history as well as present and future developments of something that is more than the Mastodon-network)
#goodread (a corollary to "sources")
#heat (rarely)
#identica (history)

Jennifer A. Kingsonm, "Buildings are banning e-bikes amid deadly battery fires" https://www.axios.com/2022/11/14/apartment-building-ban-e-bikes-battery-fire-micromobility-scooter
« Most fires are linked to batteries that don't meet safety standards, Lovell tells Axios. And many consumers don't distinguish between e-bikes and e-scooters and e-mopeds, which can be more likely to have dodgy batteries, she said. »
