Spanish scientists develop thermoelectric heat pump for thermal energy storage

A Spanish research group has investigated how thermoelectric heat pumps may be used as power-to-heat technology to increase temperatures in thermal energy storage systems. It found the proposed system configuration may achieve an overall efficiency of 112. 6% at at 135 C. Researchers from Spain have designed a novel thermal energy storage (TES) system that utilizes a thermoelectric heat pump (TEHP) as a power-to-heat technology to reach elevated temperatures in charging the storage system itself. "The analysis focuses on assessing the coefficient of performance (COP) and heating capacity by varying ...
