ARC Discovery Project

The ARC Project “High Energy Density – High Delivery Rate Thermal Energy Storage” has been funded:

The intermittency of renewable energy sources will be addressed using new thermal storage media.
Advanced heat transfer modelling and in situ neutron diffraction and imaging will 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 MJ/L) requires storage volumes as little as 5% of those relying
upon heat capacity and the metal matrix has a hundred-fold greater thermal conductivity than current
systems. A range of such materials will be engineered for concentrated solar thermal and space heating
applications.
