Ultra-high-temperature electrocaloric heat pump

open access: yesEnergy Conversion and Management
Nearly a quarter of waste heat is generated at temperatures exceeding 300°C, yet conventional heat pump technologies remain inefficient in recovering and utilizing heat from such high temperature sources. In this study, we introduce a novel electrocaloric heat pump designed to operate with heat sources and sinks at ultra-high temperatures. The proposed
