Several geopolymer samples have been fabricated and characterised by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Additionally, the density and heat capacity have been determined. Lastly, the cost of the material and packed bed system was estimated showing that the geopolymer-based systems are potentially 35% cheaper than the traditional 2-tank molten salt systems.application/pdfeng(c) Jacob, Rhys et al., 2020Emmagatzematge d'energia tèrmicaMaterials a altes temperaturesMicroscòpia electrònica d'escombratgeHeat storageMaterials at high temperaturesScanning electron microscopyinfo:eu-repo/semantics/article7214362022-06-21info:eu-repo/semantics/openAccess
