The technical and economic feasibility of utilizing phase change materials for thermal storage in district heating networks

This study investigates the feasibility of utilizing phase change materials (PCM) for thermal energy storage (TES) within district heating applications (DHN). The increased storage capacity associated with PCM can increase the contribution from LZC technologies and reduce cycling of plant which in t...
