Power from Geothermal Sources
Since all market and scientific attention has been focused on the higher-temperature geothermal opportunities both within the U.S. and internationally, there is no
real assessment of the size of the lower-temperature geothermal market opportunity that PwrCor’s technologies and techniques are now opening up.
Best estimates place the size of the market at least 3 times the existing opportunity, or over 20,000 Megawatts (20 Gigawatts) in the U.S. alone – and possibly
as great as 10 times the existing market.
PwrCor can be deployed in three major ways –
(1) provide solutions to the new and totally unexploited low and ultra-low-grade geothermal market,
(2) improve the efficiency of the existing high-temperature geothermal installations by tapping the remaining waste heat after the primary heat cycle is complete (bottoming cycle), and
(3) utilize geothermal and other wells which were drilled at great expense but which yielded heat flows of too low a temperature or inadequate volume, especially attractive because the sunk cost of these unutilized wells can now be recouped.
There are enormous and largely unexploited low-grade geothermal heat sources throughout the United States. Most of these have been identified and mapped. These vast geothermal resources are as yet untapped because older competing technologies are incapable of converting low volume heat flows of low-grade heat into power economically.
