Experimental investigation of a cementitious heat storage medium incorporating a solar salt/diatomite composite phase change material

Thermal energy storage is one of the most appropriate technologies to correct the gap between the energy generation and supply and to address energy challenges. Concrete is generally the preferred “solid” heat storage material because its low cost and good thermal conductivity. The major disadvantage is its low heat stored density involving the use of large amounts of concrete. Latent heat storage materials (or phase change materials), have...
