Résumé

Conventional heat pump technologies operate efficiently at low and medium temperature levels but face fundamental limitations when heat delivery above 300 °C is required. Decarbonising high-temperature industrial processes demands alternative solutions capable of achieving substantially higher temperature lifts. Solid-state heat pumping technologies represent a promising pathway, with theoretical potential to deliver heat at temperatures approaching 1,600 K. Technologies based on magnetocaloric, electrocaloric, mechanocaloric, and thermoelectric effects rely on solid-state phenomena and eliminate gaseous refrigerants, reducing leakage risks and improving environmental compatibility. To realise their high-temperature potential, intensified materials research is required to expand operational temperature ranges, enhance energy density, and ensure long-term stability under cyclic loading. At the same time, engineering efforts must focus on device integration, thermal management, and scalable system design. This paper reviews the potential of emerging solid-state high-temperature technologies and emphasizes a roadmap bridging materials science and engineering to accelerate the development of next-generation solid-state heat pumps and energy harvesting systems.
