Team develops new way to extract thermal energy from waste heat sources and reuse it via pressure control

https://techxplore.com/news/2023-02-team-thermal-energy-sources-reuse.html

"barocaloric thermal battery cycle: (1) thermal charging upon pressurization, (2) storage with pressure, and (3) thermal discharging upon depressurization... ammonium thiocyanate... Discharge heat 43 J g-1 or temperature rise of 15 K... 11X greater than mechanical energy input... crystal structural phase transition from monoclinic to orthorhombic phase at 363 K... low-temperature industrial waste heat harvesting and reuse, solid-state refrigeration heat transfer systems, smart grids, and residential heat management"
