“…2,9,33 In other studies, no mass loss after thermal cycling was observed. 20,35 In the study by Grosu et al, 23 river rock and basic oxygen furnace slag samples showed minor mass loss at 170 C due to the organics decomposition and water removal. On the other hand, magnetite samples gained mass after thermal cycles because of oxidation of Fe 3 O 4 to Fe 2 O 3 .…”

“…Waste-based materials such as industrial byproducts, 15,16 municipal solid wastes, 17 inertized wastes, 17 asbestos containing wastes, 18,19 and industrial furnace slags [20][21][22][23][24] are promising low cost and ecofriendly STESMs for high-temperature industrial applications. These studies prove that STESMs developed from waste-based materials offer good thermal properties and cheapest solutions for high-temperature applications.…”

Summary Packed‐bed thermal energy storage (TES) system filled with low cost and sustainable sensible thermal energy storage material (STESM) is a promising option for medium–high temperature applications. STESM developed from demolition wastes are eco‐innovative and compatible with circular economy. They can be used in solar heat industrial applications up to 750°C. One of the main concerns that should be taken into consideration is the stability of STESM developed from demolition wastes in direct contact with hot heat transfer fluids (HTFs). In this study, thermal and mechanical stability of STESM developed from demolition waste were investigated using repeated heating and cooling cycles in Therminol 66 synthetic oil as HTF at 150°C for up to 500 hours. The characterization results before and after thermal cycling showed that new STESM developed from demolition wastes is thermally and mechanically stable. Also, strong oil penetration into the STESM samples improved the porosity, strength, and specific heat capacity. The specific heat capacity and mechanical strength values increased from 1330 to 1490 J/kgC and from 4 to 6 MPa, respectively. These results suggest that STESM samples developed from demolition waste can be used reliably in solar heat industrial applications for long term.

Integration and Optimal Control of MicroCSP with Building HVAC Systems: Review and Future Directions

Heating, ventilation, and air-conditioning (HVAC) systems are omnipresent in modern buildings and are responsible for a considerable share of consumed energy and the electricity bill in buildings. On the other hand, solar energy is abundant and could be used to support the building HVAC system through cogeneration of electricity and heat. Micro-scale concentrated solar power (MicroCSP) is a propitious solution for such applications that can be integrated into the building HVAC system to optimally provide both electricity and heat, on-demand via application of optimal control techniques. The use of thermal energy storage (TES) in MicroCSP adds dispatching capabilities to the MicroCSP energy production that will assist in optimal energy management in buildings. This work presents a review of the existing contributions on the combination of MicroCSP and HVAC systems in buildings and how it compares to other thermal-assisted HVAC applications. Different topologies and architectures for the integration of MicroCSP and building HVAC systems are proposed, and the components of standard MicroCSP systems with their control-oriented models are explained. Furthermore, this paper details the different control strategies to optimally manage the energy flow, both electrical and thermal, from the solar field to the building HVAC system to minimize energy consumption and/or operational cost.

“…The publications reporting the evolution of thermal conductivity on concrete at high temperatures are limited in number. Several authors reported measurement of thermal conductivity on concrete used for TES, but the maximum temperature evaluated was 450°C [44,48,75]. Recently innovations in the molten salts have demonstrated its stability at temperatures of 600°C [14].…”
