The project HT-PCM aims at providing a feasibility study of using phase change materials (PCM), e.g. erythritol, as storage solution for temperature ranges in between 110 °C to 120 °C. The storage concept is designed to be integrated with solar thermal collectors to provide solar process heat to industries. The proposed PCM solution is expected to decrease cost, achieving a latent energy density in the range of 80 kWh per m³ of storage volume at a cost lower than that of synthetic oil.
In «Slurry-Hp I» we have shown the potentials of cost reduction of using the ice slurry technology with the supercooling method for solar-ice applications. First work on supercoolers was done in «Slurry-Hp II» and it is currently being developed in the «H2020 TRI-HP». «Slurry Store» will work towards the development of an ice slurry storage concept for this application. Several options for charging (icing) and discharging (melting) the slurry storage will be experimentally evaluated and a design will be proposed. Last but not least, an ice releaser (cristallizer) to ensure a continuous ice slurry production will be implemented in the laboratory set-up for a capacity of 5 kW.
