Abstract: 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 turn can increase lifespan and improve the overall system performance. The results suggest that PCM such as Sodium Acetate Trihydrate can be economically and environmentally feasible when utilized for TES in DHN; however, cost reductions of over 50% to approximately £57/kWh are required to provide financial savings over traditional sensible storage solutions such as pressurised hot water tanks. Air pollution and CO2 emissions can be reduced through the increase in heat pump contribution.
