New Berkeley Lab Project Turns Waste Heat to Electricity

Power Generation - Apr 13, 2017

Vast amounts of energy are wasted every year in the form of heat. A new project led by the Department of Energy’s Lawrence Berkeley National Lab (Berkeley Lab) seeks to efficiently capture that heat and convert it to electricity, potentially saving California up to $385 million per year.

With a $2-million grant from the California Energy Commission (CEC), Berkeley Lab is partnering with Alphabet Energy to create a cost-effective thermoelectric waste heat recovery system to reduce both energy use in the industrial sector and electricity-related carbon emissions. ICF International estimates that such a system could save California 3.2 million megawatt-hours per year in energy while also increasing electrical reliability. The funding comes from CEC’s Electric Program Investment Charge (EPIC) program, which funds clean energy innovation to reduce pollution, foster economic development, and meet the state’s climate goals.

“The potential to create electricity from waste heat in California has not been tapped significantly due to the lack of suitable waste-heat-to-electricity conversion technology,” said Ravi Prasher, director of Berkeley Lab’s Energy Storage and Distributed Resources Division. “Thermoelectrics is one of the most promising technologies for waste heat conversion out there, but the biggest challenge has been to find a reliable and cost effective material that can work at high temperatures.”
