Storage system for University of Stuttgart
Storasol has delivered a high-temperature thermal energy storage system capable of reaching 900°C to the University of Stuttgart for demonstration purposes and future Carnot battery concepts.
News
Storasol-Small Power-to-Heat Modul
Our new sand storage unit (S-PtH module)—designed for the cost-effective utilization of surplus electricity from PV systems and flexible electricity tariffs—is currently in the testing phase.
NEW CO-OPERATION PARTNER IN GREECE
We are happy to announce that Storasol has signed an co-operation agreement with MES Energy SA for the market in Greece.
4th IWCB – OPTES-GT Battery Development
At the 4th International Workshop for Carnot Batteries, Dr. Schneider presented the current state of development of the OPTES-GT battery.
Our new pressurized HTTES – TESS 3B
Our Pressurized High Temperature Thermal Energy Storage TESS 3B was developed specifically for use as a thermal power storage (Carnot battery).
OPTES-GT BATTERY
For lower power classes, the OPTES battery has been further developed into the OPTES-GT. The OPTES-GT Battery is based on an open Brayton Cycle.
Economic comparison of OPTES storage and Li-Ion storage
STORASOL presented the following study as part of the StoreEnergy trade fair. In a current and a future scenario, an economic comparison of the combination PV & OPTES ® battery versus PV & Li-ion battery is presented. The results show both for the current and
VHTTES – Very High Temperature Thermal Energy Storage
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.
Material tests with iron silicate (1.8-2.4 mm)
Iron silicate with a grain size of 1.8-2.4 mm was tested as a new storage medium in our TESS 3A test storage facility. The first measurement results show very successful tests with an approx. 15-20% higher energy density compared to silica sand.
Material test at over 1000°C
Storage materials can be tested with temperatures of more than 1000 °C in the latest experimental set-up.
