Recovering electricity from heat storage hits 44% efficiency
Closing in on the theoretical maximum efficiency, devices for turning heat into electricity are edging closer to being practical for use on the grid, according to University of Michigan research.
Heat batteries could store intermittent renewable energy during peak production hours, relying on a thermal version of solar cells to convert it into electricity later. Bosun Roy-Layinde, a recent PhD graduate of chemical engineering, demonstrates how he measures the amount of power generated by his thermal photovoltaic cells. The team has applied for patent protection with the assistance of U-M Innovation Partnerships and is seeking partners to bring the technology to market.
