A start-up says it's devised a system to produce electricity from wind turbines even when there is no wind, taking on the major challenge of storing wind-generated power.
General Compression, based in Attleboro, Mass., last week said it received a $5 million round of seed funding to commercialize a wind-power storage system that uses compressed air.
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
