Through the peaks of summer air-conditioning and winter cold snaps, the system must remain always ready for spikes in demand.

Seacoast Firm Stores Energy With Air http://nhpr.org/post/who-needs-batteries-seacoast-firm-stores-energy-air <p>Solar and wind power are intermittent, and if enough of them are powering the grid, some kind of storage will be necessary. And storage means batteries, right?</p><p>Not necessarily. In Seabrook New Hampshire, a start-up is doing it with compressed air.</p><p></p><p>It’s pretty easy to see how energy stored as compressed air works: When you let go of a full balloon, it flies all around the room because of the energy stored inside. So if you use electricity to run an air compressor, you basically just need to find a way to run that compressor backwards to get electricity again.</p> Fri, 01 Mar 2013 15:52:21 +0000 Sam Evans-Brown 22896 at http://nhpr.org Who Needs Batteries?
