Welcome to Cool Energy
Making Clean Power with Clean Air
We can turn wasted exhaust into energy. Cool Energy’s novel ThermoHeart Engine is an energy efficiency solution that converts operational lower temperature (100°C to 300°C) waste heat into electricity, providing quick payback time and clean electricity. The ThermoHeart Engine captures waste heat that an industrial process is already emitting, and turns it into clean and renewable electricity. Harnessing heat from this previously untapped temperature range opens an entire new set of renewable and alternative opportunities for economical power generation. Using Cool Energy’s ThermoHeart Engine improves overall energy and operational efficiency.
Due to the potentially rapid payback, the initial market application for the ThermoHeart Engine is the recovery of wasted and exhaust heat to produce electricity. These Waste Heat Recovery settings including commercial and industrial facilities, remote and military generators, biomass, solar thermal, and geothermal can all benefit from using the ThermoHeart Engine for electricity production.

The ThermoHeart Engine can be used to recover low grade waste heat that has previously been uneconomical to recover, from any hot gas up to 700C, the heat flow can be used to drive a heat transfer fluid temperature to 100C to 300C. Chances are if an industry needs to heat, bake, cure, melt, dry, roast, or form something in their process, they also have a waste heat stream that can be captured. Cool Energy’s approach boosts operational efficiency and reduces fuel consumption.
Potential waste heat sources include:
- Commercial and industrial processes
- Diesel Generators (remote and military uses)
- Pollution control equipment
- Biomass processing
- Solar Thermal
- Ship propulsion engines and shipboard generators
Waste Heat Recovery
Waste Heat Recovery
Anywhere there is an industrial process that involves transforming raw materials into useful products – steel mills, paper plants, refineries, chemical plants, oil and gas pipelines, pollution control equipment, and general manufacturing — heat is wasted as a result. If not captured and used to generate emission-free renewable-equivalent power, waste heat is released to the atmosphere through stacks, vents, flares and mechanical equipment. 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 emission-free electricity, allowing the industrial user to put their wasted energy back into the process that created it. Installing the ThermoHeart Engine(s) on waste heat streams from industrial processes can have payback times as short as one year.
According to the United States Department of Energy, up to 50 percent of the energy from all fuels burned in the U.S. ends up in the atmosphere as waste heat. Research indicates that recovery of the energy waste from industrial facilities could fulfill up to 20 percent of total U.S. electricity demand and simultaneously effect a 20 percent reduction in greenhouse gas emissions. It is estimated that 11GW of power could be generated in the US alone if the best quality waste heat from commercial and industrial operations were collected and converted to electricity. Public benefit of Waste Heat Recovery
Pollution control equipment is used to destroy particulates and volatile organic compounds (VOC’s) that are produced by industrial processes such as coffee roasting, metal coating and painting, and cement manufacturing. The gas that is emitted from the combustion chamber of this equipment has a temperature that ranges from 300C to 600C. This clean, hot gas is passed through a heat exchanger and then circulates into Cool Energy’s ThermoHeart Engine, producing electricity from the Stirling cycle machine. This electricity reducing the customer’s electricity bill and operating costs. For plants operating on a 24/7 schedule in Europe or Japan, the payback times are as short as two years.Pollution control machines of this type are used across many different processes, including food processing, baking, brewing, metal finishing, paint spraying, soil remediation, and petroleum processing.
One application being targeted for initial product deployment is waste heat recovery from the exhaust of diesel gensets (DGs) and shipboard generators. With an easy retrofit, Cool Energy’s engine can boost the output of DGs by 10% to 20% when recovering the waste heat the generator exhausts. There are two basic options available for how to use the electrical energy produced by the ThermoHeart Engine: load reduction and battery charging. In remote and military settings where fully burdened diesel fuel can cost up to $15/gal including transport costs, the payback period for the engine can be less than one year. The reduced requirement for transport of fuel is a highly valuable benefit to the military, as the majority of present war casualties occur during resupply missions of water and fuel.
