This research project “Thermal Energy Storage”, conducted under the supervision of Dr. Alissar, focuses on modeling and performance optimization of a structured regenerative thermocline thermal energy storage (TES) system using concrete as the primary storage medium.

The objective is to investigate low-cost, durable concrete-based materials for sustainable thermal energy applications, supporting renewable energy integration and decarbonization. The project involves developing numerical models to simulate transient heat transfer within the concrete storage structure, analyzing temperature distribution, thermal stratification, storage capacity, and round-trip efficiency under varying operational conditions.

Key design parameters—such as concrete thermal properties, flow rates, and geometric configurations—are evaluated to optimize system performance and thermal stability. Currently in the testing and prototyping phase with a team of 2–5 members and in operation for less than 12 months, the project has no revenue model at this stage.

Expenses: Concrete samples, thermal insulation, thermocouples, data acquisition systems, heating elements, prototype fabrication, safety equipment, and software licenses.
Funding: Currently supported by the Faculty of Engineering at the American University of Beirut (AUB), which provides laboratory facilities, infrastructure, and partial material support.
Challenges: Securing funding for experimental validation, high-temperature thermal cycling tests, instrumentation, and prototype scaling.
Vision: To advance affordable, efficient, and sustainable thermal energy storage solutions—with potential applications in concentrated solar power and industrial heat recovery—by bridging engineering innovation with real-world feasibility, supporting renewable integration, industrial decarbonization, and long-term climate resilience.
