Waste Heat Recovery – Cool Energy

If not captured and used, waste heat is released to the atmosphere missing an energy efficiency opportunity. Waste Heat Recovery is the process of collecting waste heat and using it to fill a desired purpose elsewhere. It is Cool Energy's novel technology that captures and converts this largely untapped waste heat to generate electricity.

Waste Heat Recovery For Desalination From Steam

Using heat pumps to condense steam in Steam Power Plants (SPPs) allows the recovery of waste heat at high efficiency. The amount of heat becoming available as useful heat at the discharge of the heat pump amounts to 150 percent to 200 percent of SPP electrical energy production. Heat rates vary from 8,500 to 10,800 BTUs/kWh.
