The prospects for ultra-high-temperature heat pumps

An international research team has reviewed emerging solid-state and gas-cycle heat pumps capable of reaching temperatures of up to 1,600 K, assessing their challenges, applications, scalability, and technology readiness levels. The researchers say these systems could outperform conventional high-temperature heating technologies by achieving coefficients of performance above 1.An international research group led by Slovenia's University of Ljubljana has conducted a review of emerging ultra-high-temperature heat-pump technologies based on solids or gases. All of those technologies, which have ...
