I think you know that any newer unusual tech related to the grid is gonna get pushback simply because its new. I had mentioned that it would be cool if people would be into flywheel energy storage. But once you start looking at it on a large scale, you get people freaking out about how dangerous it could be if the flywheel explodes when spinning at high speeds. There's just no winning with people sometimes.
you do know that flywheel systems have been used for grid storage for over ten yrs …
Not really. It’s just the technology evolved quickly, including safer options. What was state of the art one year become old two years later, with lessons learned each time this stuff happens. If you made a decision now, you’d take into consideration all available technologies, and how they stack up against the costs and liabilities. If you went for something less safe, the lawyers will point that out when the lawsuits happen.
No, the mega packs were the first fire, due to water intrusion; different BESS. There are several BESS facilities built on that site. The recent fire, I believe, was the first one commissioned.
Indeed I do, I just imagine the possibility of having them at a more commonly-available scale. It'd be cool, that's all.
Although if you think the failure modes for lithium ion batteries are bad . . . .
Hey @neptronix I found one of them! Told you, just mention something different and new and someone will be along shortly to tell you how bad it could be
The utility flywheel systems have them in containment pits to lower the risks.
?? Economical ?…i dont think that is a term associated with utility batteries.

Yep. With any energy storage system, uncontrolled release of that energy is the risk. With flywheels, all that energy is released in tenths of a second. At least batteries burn for a few hours, thus slowing the release of that energy.
Not exactly flywheels, but hydro generators can run synched to the grid, spinning but delivering no power, but because they are synched, they provide frequency control. They can still sell their capacity into the market, since they're considered spinning reserves, and if they are dispatched to generate, they make money on the energy too.
Yes, but certainly not a storage function, and not limited to Hydro ,..all the big steam driven generators also can do this.
