Storing Wind Power for Later Use
There are several "limitations" to wind power --- one is that the source is concentrated far from the using population (issue with transmission). Another is that wind is available when demand for power is not; so there for the need to "store the wind energy".
Check out this possible solution from Iowa ...
" ... municipal utilities ...are planning to build a new energy park that would integrate a 75-150 megawatt wind farm with Compressed Air Energy Storage (CAES) technology."
" ... Iowa Stored Energy Park (ISEP), will use ... wind energy that is not being sold on the grid at that time -
- to store air in an underground geologic structure of porous rock. ... as demand for electricity rises, the stored air will be released, heated, and used to drive generators -- in turn producing electricity for residents in Iowa, Minnesota and the Dakotas."
"F ... hopes that construction on the park will commence in two years. ... expected to be fully operational and providing electricity to Iowa and surrounding states by May 2011."
