New Jersey Utility Invests $20 Million Into Compressed Air Energy Storage - PSEG announced that it would be investing $20 million over the next three years into developing underground compressed-air storage systems for wind turbines. Currently there are two Compressed Air Energy Storage (CAES) systems operating in the world, one in Alabama and the other in Huntorf, Germany. (TreeHugger Aug. 29, 2008)
Energy Storage and Power Corporation - ESPC developed a Compressed Air Energy Storage (CAES) plant based on Dry Air Injection that reduced plant costs by more than 50%. It is a cost effective way to store hundreds of MW’s of off-peak electric energy from coal, nuclear or wind power plants underground and make it available during peak electric hours.
Iowa to Combine Wind Energy & CAES Technology - Municipal utilities in Iowa are planning a new energy park that would integrate a wind farm with Compressed Air Energy Storage (CAES) technology. The Iowa Stored Energy Park (IESP) will use low-cost, off-peak electricity and wind energy to store air underground in porous rock. As demand rises, the stored air will be used to drive generators. (Renewable Energy Access January 12, 2007)
Compressed air wind turbines - General Compression thinks it's found a way to make wind power available on-demand using turbines to compress air and store it underground. A pipeline network collects and stores compressed air and a power plant of expanders and generators produces electricity when needed. Wind farms could sell power during peak demand, making them grid compatible. (Inside Greentech Mar. 20, 2007)
CAES - McIntosh unit 1 was declared commercial May 31, 1991. The 100-megawatt CAES unit uses air compressed and stored in an underground cavern in the generation process. When the compressed air is needed for generation, it is mixed with natural gas in a convention gas turbine combustion process to generate electricity. The plant uses off-peak electricity to pump air into the cavern, then uses the air in the generation process during peak periods.

Storing energy in magnetic fields - Superconducting Magnetic Energy Storage System or SMES is a way of storing electrical energy in magnetic fields. Chubu Electric Power and Furukawa Electric are creating an SMES not for long term storage, which SMES are not great at right now, but for quick energy bursts. SMES can store and release lots of energy very quickly like a capacitor. (AutoblogGreen Jan. 31, 2008)
Neptune Systems - Developing tidal energy converter systems based upon magneto hydro dynamic (MHD) concepts that can convert tidal motion directly into power using no moving parts. This device can simultaneously store the electricity it produces or that is produced by other generators (like offshore wind turbines) with a high storing capacity.
Ultraconducting Magnetic Energy Storage (UMES)
Advantages: Once polymer Ultraconductors are made into long wires, and assuming they sustain as expected, maintaining persistent currents, UMES are likely to perform at least as well as superconductors, only without the expensive and complex cryogenic cooling.
Some years ago, Magnetic Power, Inc. cooperated with a scientist at the Los Alamos National Laboratory who invented a technique of fabricating SMES perhaps eight feet in diameter. These could be produced in a factory and easily transported to their ultimate location. Several could be stacked and linked together by utilities to provide whatever amount of energy storage was needed. This would allow base load power plants to run at constant speed all day and night with great economic and fuel saving advantages.
Vehicles equipped with MPI’s GENIE™ generators could employ UMES instead of ultracapacitors for peak loads. GENIE (Generating Electricity by Nondestructive Interference of Energy) will replace any need for batteries.
The power grid could employ GENIE Vehicle-to-Grid (V2G) technology, which would allow utilities to maximize their plant and distribution system efficiencies. Cars, trucks and buses would wirelessly transmit up to 150 kW to the local electric power company. Peaks and valleys of electricity demand would no longer be a major concern.
