[…] Another ARPA-E Winner: General Compression’s Renewable Energy Storage Ramps Up in 30 Seconds – “One of the success stories at the recent Department of Energy ARPA-E summit held to highlight innovators funded under the $400 million to find renewable energy innovations in the Recovery Act, is General Compression (GC). The start-up is developing an innovative compressed air energy storage system that will help get more renewable energy on the grid….” […]

Yes, I have corrected my earlier version. My mistake.

The idea of having compression in the nacelle has been dropped–this was a good idea originally but not the most prctical.The compression expansion engine is electrically driven from wind and any excess power source.Fossil fuel would be used if power for storage came from Gas or Coal fired power plants

Whoever cracks this grid storage challenge is going to make a hell of a lot of money. Fortunately, we’ll probably end up with a portfolio of solutions so we won’t be dependent on any one of them. Another ARPA-E winner with a display at the Energy Innovation Summit was MIT’s Donald Sadoway and his group building liquid metal batteries.

Good point. Should read ‘anywhere with suitable geologic storage.’ (The company also includes depleted gas or oil fields as another storage option) Will revise.

I’m a little confused by the article. It says that like traditional CAES, the air is stored in salt or saline aquifers. Then it says that since it doesn’t use natural gas, it can be sited anywhere. Well, it’s actually not that easy to find suitable sites in salt or aquifers. It’s probably easier to site the projects near gas lines than it is to find the perfect geology. In any event, it will be interesting to see what a real project looks like.

Compressed Air Energy Storage (CAES) with a compressor right in the nacelle of a wind turbine is indeed great innovation. The way research is going on in Renewable Energy especially Solar and Wind shows the ambitious targets set by US in Renewables will certainly be achieved.
