WP3.2 Compact latent heat energy storage

Prof. Eames (Loughborough University)

A nearer to market interim solution to the challenge outlined in WP3.1 is a phase change latent heat energy storage approach. The theoretical effective energy density is several times greater than a water store over a specified operating temperature range but is subject to parasitic heat loss over time. This WP will address how storage system design affects charging and discharging at specified temperatures while maximising energy density and minimising parasitic heat loss. This project will design, develop and test a prototype system scalable to meet 2-4 hours of maximum winter space and water heating load. Such a storage system would enable significant peak electrical load management.
