This diagram shows the stages of operation of a battery designed for heat harvesting. 1) Battery is heated so that its voltage becomes lower. 2) Battery is charged at high temperature, using low voltage. 3) Battery is cooled down, causing its voltage to become higher. 4) The battery is discharged at low temperature, with the high voltage. The voltage difference in the output comes from heat that was absorbed in the process.
Electrochemical approach has potential to efficiently turn low-grade heat to electricity.
Vast amounts of excess heat are generated by industrial processes and by electric power plants; researchers around the world have spent decades seeking ways to harness some of this wasted energy. Most such efforts have focused on thermoelectric devices, solid-state materials that can produce electricity from a temperature gradient, but the efficiency of such devices is limited by the availability of materials.
Now researchers at MIT and Stanford University have found a new alternative for low-temperature waste-heat conversion into electricity — that is, in cases where temperature differences are less than 100 degrees Celsius.
The system can efficiently harness even relatively small temperature differences, such as a 50 C difference.
“One-third of all energy consumption in the United States ends up as low-grade heat.”
