Company Developing up to 10GWh of energy storage in state using its patented A-CAES technology.
Advanced-Compressed Air Energy Storage (A-CAES) is a long-duration energy storage system that combines components from existing energy systems to create an advanced, emissions-free storage system that is low-impact, cost-effective, and can be located where the grid needs it. This innovative use of proven technologies provides a scalable, reliable and bankable energy storage solution for utilities and regulators.

Compressing air takes energy that can be released when the air decompresses. I read about another storage mechanism that heats vast bins of basaltic pebbles and then generates electricity with that heat. Glad folks are thinking outside the battery box.
During off peak hours, water is pumped up to it.
During peak hours, water from the lake is run h=through turbines to produce electricity.
Why not? I've seen some cars online that run on compressed air.
Watt’s[sic] the round trip efficiency?
All I know is, compressed air is terribly inefficient in factories and such. High energy conversion losses, both ways.
All in, my guess is <10%
I remember those, but this is supposed to be some sort of battery. Drop it and it’s like an airbag going off?/sarc
The system of lakes and dams on the Salt River in Arizona does exactly that.
Makes for some fun rides in the summer, tubing down the Salt.

Takes a lot of power to compress air. The factory I worked at had big problems if the compressor room went down.
Yeah ... and Brilliant Light Power has another demo on the 19th and 20th of this month. Should be interesting. Perhaps they will demo a turbine-driven electric generator at 150 kW (electric) this time.
“...electricity, all of which is sent to New York City.”
Well, THERE’s your problem right there, lady.

There is still time to get in on my high-tech start-up though. It’s called Sun Wind Deliverance Yay! Just PM me with your banking info and how much you want to invest and I’ll get right back to you. the nickname for the company is SuWinDelYa.
Solindra, is dat U?
We have one near here, pump storage called Bear swamp. Air compression technology is very inefficient IMHO.
Compressed air storage has been used in Germany for decades. They used abandoned salt mines.
Sure but that’s not a parallel situation if your primary goal is to time shift energy production and consumption. If you have lots of excess wind power during times of low demand it doesn’t matter if the storage mechanism is inefficient, as long as allows you to store energy til it’s needed.
When Musk hits $56 per KWH storage cost, as he projects, and terawatt level of production; that will end compressed air, tidal, flow battery, fusion reactor and other electric generation happy talk.
It is kinetic energy. EXTReMELY expensive to compress air for storage later.
But since ‘we’ can’t build dams and store energy in reservoirs I suppose compressed air is sensible to the green sycophants. It is more expensive and easier for politicians to grift off the system.
water storage
Yup, about as simple as you can get.
you can use heavy rotating mass as well
Very few people listened when I said Liquid Organic Hydrogen Storage, but finally people are starting to do so.
Soon you will see these plants everywhere taking excess energy splitting it into hydrogen and storing it in a stable at normal temperature liquid form
