Automotive Waste Heat Recovery

Nearly two-thirds of the energy produced by a typical gasoline engine is lost through waste heat. A thermoelectric device can capture some of that waste heat and convert it to electricity.

With approaching global requirements for vehicle carbon emissions and calls for cleaner vehicles, the Thermoelectric Generator (TEG) is at the technological forefront as a solution for meeting changing market demands. 

In 2004, we began developing high efficiency thermoelectric waste energy systems for passenger vehicles for the U.S. Department of Energy (DOE) Freedom Car Office. After delivering working prototypes to BMW and Ford, our TEG technology was proven by producing a significant amount of electricity.

We’ve been awarded an additional $8 million grant from the DOE to continue to lead development of the new energy recovery system for commercialization “on the scale needed to positively impact the reduction of greenhouse gasses,” according to the DOE grant. Working with our partners, Ford and BMW of North America, the project is to be completed in 2015.
