Pairing the Solar Thermal Collector and the Organic Rankine Cycle Turbine
Kalahari Greentech, Inc. released a statement this week detailing the study conducted on the gas turbine Kalahari has found that was designed to operate in the temperature range of its solar collector. The turbine design focuses on waste heat around the range of 100 degrees Centigrade or 212 degrees Fahrenheit. The efficiency of the turbines improves with an increase in the temperature difference.
The ORC (Organic Rankine Cycle) turbine under study was designed to use waste heat from various thermal related processes. Since the solar collector operates in the same temperature range, the two systems are well-suited for working together.
The Tri-brid system competes successfully with photo-voltaic generation and is cost-effective. Kalahari’s Solar Collector System also presents opportunities for other sources of waste heat to be integrated into the basic power generation system.
According to a U.S. Department of Energy news release dated March 25, 2009, entitled, “Solar Energy Grew at a Record Pace in 2008,” solar energy deployment increased at a record pace in the United States and throughout the world in 2008. On March 19, 2009 the Solar Energy Industries Association (SEIA) released its “2008 U.S. Solar Industry Year in Review,” which found that U.S. solar energy capacity increased by 17% the past year, reaching the equivalent of 8,775 megawatts (MW). The SEIA report also notes that the United States installed 342 MW of solar photovoltaic (PV) electric power, 139 thermal megawatts (MWTh) of solar water heating, 762 MWTh of pool heating, and 21 MWTh of solar space heating and cooling in 2008.
