At this point I wonder if the environmental impact from a lithium battery fire would eclipse the impact from a worst case scenario at a modern nuclear power plant.

There is far far more in terms of containment in the nuke plant, but, the stuff inside is much more dangerous and longer lasting.

We will find out soon about the environmental impact from soil testing. Results are supposed to be on the county website [1] at the end of May [2], and that's a few days away.

This is pretty much a worst-case scenario for battery fire size and spreading. It is a very early large-scale battery deployment with what appears to be completely insufficient fire suppression, and very little thought for fire isolation. It was a tightly packed indoor multi-story facility, very unlike the more typical outdoor shipping-container style facility.

Yeah it was pretty bad, but the siting is excellent. If an organization simply must use these unstable batteries, they can build them below grade at this site and fight fires with the simplest possible means: pushing a pre-placed heap of beach sand into the pit.

I'm not even sure if the fire was bad. It was visible, surely, and people are scared of the unknown. But the preliminary results are that there's nothing unusual on the soil:

Metallic taste in the air was the worst symptom that people reported, and people here were complaining of metallic taste in the air, 40 miles away, upwind from the site, for months. So unless something really shocking comes up in the report this month I think battery fires are mostly a concern for insurance companies and fire code to protect fire fighters and other structures. IMHO building below grade and dumping dirt seems to be massive overkill; just separate containers and don't stack them so that a lower fire spreads to multiple upper containers, and things are probably fine.

The Santa Cruz area is obviously primed for a chemtrails-like freakout. Oddly I've never heard anyone complaining about the fact that there's a combustion generator right next to it that's been spewing who-knows-what into the atmosphere for decades.

I live close to this and the event is proving the horseshoe political theory very very correct.

You get the lefty RFK Jr. anti-science types becoming very anti-batteries, collaborating with the extreme-right-wing coalition of mountain hermits, rednecks, and extremely wealthy Monterey peninsula types.

We are a community that is easily spooked, but the batteries have really brought out the crazies.

These guys love their off-grid and solar and batteries tbh.

Well, some of them. Some of them love propane and generators. Maybe solar, but not always.

In fairness a good number of them seem to live in Alaska or other places where solar is effectively pointless and totally useless for months of the year.

I honestly have no idea whether you are right or whether that county supervisor has merit to what they said. That is why we need journalists to actually be people who want to seek truth and inform their audience of that truth rather than just being a public stenographer. A good journalist should have skepticism towards what they are told by public figures and needs to consider whether what they are told is accurate before repeating it without any qualification.

But then again, there doesn't even appear to be a byline on this article, so who knows who actually wrote it. If no one is willing to stand behind these words, maybe it wasn't even a human who wrote them. Maybe that quote from some unnamed person is a complete hallucination of some AI. I guess it's up to the reader to do their own research, which makes you wonder what role the journalist is even serving in this instance.

to be fair, there really was a fire, and it was a bad one. You can't just lose 80% of the capacity at one of the largest battery storage facilities in the US in a multi-day fire and hand-wave it away as some kind of conspiracy theory.

It's also just bad optics, unfortunately. A coal power plant kills people living nearby slowly over the course of decades, a battery fire might injure a few people but it does so in a way that makes headlines. No one cares about boring lawsuits over a power plant being turned off next year anyway, and that is part of what makes these kinds of stories so frustrating!

This event demonstrated that battery systems need to be designed, like any engineering system, such that any failure is not catastrophic. They failed on this battery plant, and regulations were put in place to prevent that for future plants.
