Using Air to make Energy from… Air!
: Posted by Robert Ballecer @ 4:49 pm (Mar/31/07) Technology No Comments »From the article: “Wind turbines typically have an onboard power generator that sends electricity down the tower and onto the grid. General Compression plans to break with that basic design and place an air compressor in the nacelle, the housing on a turbine where the generator usually sits. Its plan calls for sending highly compressed air down the tower and into underground storage, such as caves or depleted gas wells, or through pipelines. The pressurized air can be released when needed to power an electricity generator, even if wind is not spinning the turbine’s blades. ”
Nice — Battery storage has always been an Achilles heel for solar and wind power — We’ve long needed a better way to store up that energy when it isn’t being used, and then deliver it when the sun isn’t shining or the wind isn’t blowing. Batteries have sort-of/kind-of worked, but the efficiency of the generation-storage-delivery cycle has never been conducive to the growth of alternative energy. — Compressed air storage would remove the notoriously inefficient and hard-to-maintain batteries from the equation and allow for mechanical storage of energy.
