OPtimization of a Thermal energy Storage system with integrated Steam Generator

Solutions developed

Since the objective is to develop a new TES-SG concept for large-scale CSP plants, i.e. 50 MWe, the experimental concept has to be verified in a relevant scale (at least 12.5 MWth), maintaining the same main thermo-fluid-dynamic parameters as the full scale system. This test section will be designed, built, and tested. Basic experimental, modelling and engineering activities will be carried out to support the design and optimization of the proposed technology. These activities include assessment of MS heat transport properties under relevant representative conditions for the TES-SG system.

Main results

Design, optimization and cost-benefit assessment for a full-scale TES-SG system (125 MWth/50MWe) will be done in the framework of the OPTS project coupled with a CSP (tower or trough) plant.
