General Compression, Inc., a Massachusetts company developing an innovative compressed air energy storage system, has signed an agreement with ConocoPhillips to develop compressed air energy storage (CAES) projects, beginning with a pilot project in Texas, using General Compression’s Advanced Energy Storage (GCAES) technology.

GCAES is a modular compressor/expander unit that has a nominal size of 2 MW and features a roundtrip electrical efficiency in excess of 70%. Unlike conventional turbomachinery-based compressed air energy storage, GCAES consumes no fuel and emits no carbon. GCAES technology can increase utility reliance on renewables, eliminate wind power curtailment, enhance transmission utilization, and make dispatchable renewable power available to customers.
Founded in 2006, General Compression, Inc. has made patent-pending advancements in the fields of isothermal compression and expansion to provide utility-scale storage for clean electricity sources such as wind and solar. General Compression raised more than $17 million in Series A financing in 2010.
