OPTES® stands for Optimized Pumped Thermal Energy Storage – Battery and combines the advantages of low investment costs with very good power-to-power efficiency. In 2020 the OPTES® Battery was presented for the first time at the IRES (International Renewable Energy Storage Conference). The publication on this can now be read under
As part of the StoreEnergy fair, STORASOL presented the following study. In a current and a future scenario, an economic comparison is made between the combination of PV & OPTES-Battery and PV & Li-Ion Battery.
The basic engineering has just been completed for the VHTTES (Very High Temperature Thermal Energy Storage) shown in the figure. The storage systems are to be used in a solar power plant and in a thermal battery for storing electricity. The two storage tanks shown are flowed through with 1000 °C hot air and have a usable storage capacity of 10 MWh each.
STORENERGY took place for the third time on the 12th and 13th of November 2019 at the Offenburg fair. The topics of the congress are storage technology, grid integration and the path to decentralized power production in order to use the energy sources economically.
