Performances of spherical macrocapsules (nodules) currently used in latent heat-based thermal energy storage (TES) industrial units have been enhanced by the addition of graphite particles to the phase change material (PCM). Two different graphite types, namely graphite flakes (GF) and expanded...

Conventional Concentrating Solar Power (CSP) technologies have been mainly developed during the eighties. They can be considered as similar to conventional thermal power processes in which the boiler has been replaced, at least partially, by a concentrated solar field producing the heat. After...
