Geothermal firms and researchers won $338 million in federal stimulus money, with California\u2019s share of the grants totaling $27 million. \u201cThe United States is blessed with vast geothermal energy resources, which hold enormous potential to heat our homes and power our economy,\u201d stated Steven Chu, Department of Energy secretary, when announcing the awards at the end of last week. The grants are to be matched with an additional $353 million in private and non-Federal cost-share funds. \u201cThis is an unprecedented federal investment in geothermal energy,\u201d said Curt Robinson, the Geothermal Resource Counsel\u2019s executive director. The biggest California award--$7 million--will go to the Lawrence Berkeley National Laboratory, Chu\u2019s alma mater. Firms and other research organizations that won grants in the state include the following: -Ormat: $4.475 million to support advanced technology to find fractures in geothermal reservoirs in Wister. -Ram Power: $5 million to improve the understanding of the geology of the geothermal rich Imperial Valley. -Regents of the University of California: $1.8 million to enhance pressure and temperature sensors in hot wells. -University of Southern California: $1.48 million for improving the techniques to identify geological field fractures to improve fluid flows. -Array Information Technology: $1.38 million to this Bay Area firm for enhanced seismic monitoring near geothermal sites -Oasys: $910,000 to tap into the power of low temperature geothermal resources in The Geysers area. -Potter Drilling: $5 million for improved and less expensive well drilling.
