Heat to Power
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 help clients in three major ways –
(1) provide solutions to the new and totally unexploited low-grade geothermal market,
(2) improve the efficiency of the existing high-temperature geothermal installations by tapping the remaining waste heat (bottoming cycle) after the primary heat cycle is complete, 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.
This will now change.
The sources of wasted heat are innumerable. PwrCor is focusing first in geothermal heat conversion, but can help provide solutions wherever suitable heat resources are found. Wherever it is used, the PwrCor technology reduces environmental impacts. And the benefits are not simply environmental -- paybacks have been shown to be extremely rapid, proving that it has an economic benefit.
One example of utilizing wasted heat is in the hydrogen production process, which generates heat that is wasted, which in turn can be used by PwrCor technology to reduce cost or increase production.
Solar heat is a nearly daily resource in certain parts of the world – parts which also need fresh, potable water. PwrCor technology can be used to convert low levels of solar heat into sufficient mechanical power to drive reverse osmosis operations wherever there is access to water, such as sea water – without even having to produce electricity.
