This project aims to address the intermittency of renewable energy sources using novel thermal storage media. Advanced heat transfer modelling and in situ neutron diffraction and imaging are intended to be used to optimise the microstructure of newly developed miscibility gap thermal storage systems. The new media store energy as the latent heat of fusion of one phase in a stable, high thermal conductivity inverted microstructure. The high energy density of the latent heat (0.5-4.5 Mega Joules/Litre) requires storage volumes as little as five per cent of those relying upon heat capacity and the metal matrix has a hundred-fold greater thermal conductivity than current systems. It is proposed that a range of such materials will be engineered for concentrated solar thermal and space heating applications.

该项目旨在解决使用新型热存储介质的可再生能源的不稳定性。先进的传热建模和原位中子衍射和成像的目的是用来优化新开发的可膨胀间隙热存储系统的微观结构。新介质将能量存储为稳定的、高导热性的倒置微结构中的一个相的熔化潜热。潜热的高能量密度（0.5-4.5兆焦耳/升）需要的存储体积仅为依赖热容的存储体积的5%，并且金属基质的导热性比当前系统高出一百倍。据建议，将设计一系列此类材料，用于集中式太阳热能和空间供暖应用。
