The Pratt & Whitney Power Systems PureCycle® power system is a closed-cycle process that uses any hot water
resource to generate 280 kW (gross) of electrical power. The system is driven by a simple evaporation process
and is entirely enclosed, which means it produces no emissions. The only byproduct is electricity, and the
fuel - hot water - is a renewable resource. In fact, for geothermal applications, the water can be returned
to the earth for re-heating, resulting in the ultimate recycling loop. Free fuel, coupled with low operating
and maintenance costs, ensure this system will have an extremely attractive payback. The PureCycle® power
system can operate on a wide range of resource temperatures starting as low as 195°F (91°C). By operating
at lower temperatures than conventional geothermal systems, the PureCycle® power system enables geothermal
wells deemed unproductive because they are below 300°F (149°C) to become viable energy sources once again.
