Sopogy, Inc.'s proprietary MicroCSP' solar collectors will be one of two unique solar technologies to begin operations today as part of a solar air-conditioning demonstration program sponsored by Southern California Gas Co. (The Gas Company). The demonstration, scheduled to run for 18 months, is part of an overall effort to provide customers with energy solutions that will reduce costs, increase efficiencies, and reduce greenhouse-gas emissions.

Sopogy's solar collectors, which were installed on the rooftop of The Gas Company's Energy Resource Center (ERC) in Downey, California, will produce 10 tons of cooling, or enough air-conditioning to cool three average-sized homes. The system will provide solar thermal heat by concentrating the sun's energy on a collection tube and heating the recirculated heat transfer fluid within the system. The generated heat will then be used in conjunction with absorption chillers to provide a renewable source of industrial cooling for the air-conditioning system at the ERC.

"We are extremely pleased to demonstrate how MicroCSP technologies can be used to produce renewable space cooling to The Gas Company," says Darren T. Kimura, CEO of Sopogy. He added, "It isn't obvious that solar thermal energy can be used to create air conditioning but the efficiencies in doing so are incredible and the system displaces the burning of a significant amount of fossil fuels."

Sopogy's MicroCSP technologies are being deployed around the world including United States, the Middle East, Europe, Asia and Hawaii. The unique scalability and modularity of MicroCSP make it ideal for distributed generation applications such as electricity, process heating, and solar air-conditioning. Sopogy has engineering partners throughout the globe, who are certified to help develop and construct solar plants in their specific regions.
