A novel standalone particle TES system is evaluated for electric energy storage. The system stores low-price, off-peak electricity as thermal energy for later dispatch to produce high-value, peak-demand electricity. The TES system uses particle-storage media at 1200°C to drive a high-efficiency combined cycle to obtain a high roundtrip efficiency.
In 2018, as part of the EDITOR Project (Funded by European funds through SOLAR-ERA.NET), CADE launched a concrete thermal storage system consisting of two containers with a capacity of 600 kWh, capable of storing thermal energy generated in a concentrating solar field and releasing that energy at a later time to generate process steam.
The energy storage system can be integrated with CSP or a standalone TES system consisting of four subsystems: (1) a novel particle heater; (2) insulated particle storage silos; (3) a fluidized bed heat exchanger (FB-HX); and (4) a power system. Preliminary component designs were performed.
Thanks to CADE’s innovative DNA and initiatives, such as EDITOR or TES4Trig, CADE has managed to develop its own solid thermal storage solutions and technologies (solidTES) based on different materials such as solid aggregates or special types of concrete.
Therefore, one key factor for thermal energy to play a role in electricity storage is to improve thermal-cycle efficiency, which is possible by adopting a high-efficiency ABCC power system that is adapted from a conventional GTCC.
