1. Biphase Energy Systems, Santa Monica, CA

Geothermal power systems using a Biphase rotary-separator turbine (RST) are compared to flash steam and binary systems. Application to geothermal fluids having temperatures from 280 to 680/sup 0/F is considered. Brine production costs, capital equipment costs, and competing system efficiencies were taken from published studies. RST performance was extrapolated from field-test results. Systems incorporating the Biphase RST are projected to produce power at a lower cost than binary or flash-steam systems over temperatures from 360 to 680/sup 0/F. Below 360/sup 0/F the binary system was cheaper than the Biphase but by less than 10%. Based on economics, the market potential for the Biphase RST was estimated at 18,600 MW compared to 17,350 MW for flash-steam, and 11,550 for binary.
