Thermally regenerative copper nanoslurry flow batteries for heat-to-power conversion with low-grade thermal energy

Hubert Girault, Pekka Eero Peljo, Sunny Isaïe Maye

Low-grade heat (below 200 °C) is available in vast quantities from industry, or from standard roof-top solar thermal collectors. However, the production of electric power from these heat sources is challenging with existing technologies. Thermally regenera ...
