This thesis investigates using geopolymer based concrete as an alternative thermal energy storage (TES) material to conventional ordinary Portland cement (OPC) concrete, particularly for high temperature concentrating solar power (CSP) applications where OPC degrades.

The work presents an effort to a methodology utilizing thermal properties measurements, numerical and experimental TES modeling, and data-driven optimization and design of TES units to introduce a more sustainable, efficient and high-temperature-stable yet scalable TES material for the renewable energy sector.
