Geothermal-Overview
Howard Rogers
Geothermal Technology- 3 major areas of
Direct use of hot geothermal fluids
Generation of electricity using-Steam (Dry & Flashed)
Geopressured
Binary (secondary fluids)
Residential & Commercial Heat Pumps
Our Focus for Central and South Texas-Only 2 areas
Residential & Commercial Heat Pumps
Generation of electricity usingGeopressured
Binary (secondary fluids)
Residential & Commercial Heat Pumps
Geothermal Heat Pumps (GHPs) take advantage of the Earth’s relatively constant temperature (about 68 degree F in Central Texas) at depths of about 10 ft to 300 ft.
They are extremely efficient.
Geopressured resources:
Geopressured resources are deep reservoirs of high-pressured hot water that contain dissolved methane.
The Department of Energy built a demonstration plant in Texas (1979-1983) which produced electricity.
Binary Generation
Recent advances in geothermal technology have made possible the economic production of electricity from geothermal resources as low as 170 degrees F.
Binary plants typically use the geothermal fluid to heat another liquid which boils at a lower temperature than water.
What does one look like? This one is for Co-production with Oil Wells
With regard to electrical generation
We hope to show that- With present technology, we can have

CPS Energy is the leader in renewable energy
It has sent out an RFP for 200 Mw of renewable energy…… that includes geothermal.
They are doing their job.Who/What is the problem?
