Application of Composite Materials for Thermal Storage in the Heat Supply System in the Czech Republic Michal VOLF1,a*, Eva NEZBEDOVÁ1,b and Radek KOTTNER2,c 1Ing.
This paper investigates the application of polymer materials for low-temperature, pressure-less a thermal storage in Czech district heating systems integrated with high-performance heat pumps.
While composite materials are widely applied in aviation and the chemical industry [4][5], their use in the energy sector—particularly for stationary thermal storage—remains less common.
