6 FAQs about [Swiss chemical steam energy storage]
What is the contribution of thermal energy storage?
Besides the well-known technologies of pumped hydro, power-to-gas-to-power and batteries, the contribution of thermal energy storage is rather unknown. At the end of 2019 the worldwide power generation capacity from molten salt storage in concentrating solar power (CSP) plants was 21 GWh el.
Can latent heat storage be used in industrial production of superheated steam?
Our study demonstrates the feasibility of using latent heat storage in the industrial production of superheated steam. Thermal energy is used for residential purposes, but also for processing steam and other production needs in industrial processes.
What is a thermal energy storage system?
In other words, the thermal energy storage (TES) system corrects the mismatch between the unsteady solar supply and the electricity demand. The different high-temperature TES options include solid media (e.g., regenerator storage), pressurized water (or Ruths storage), molten salt, latent heat, and thermo-chemical 2.
Which fluid is used for energy storage in CSP plants?
For energy storage in CSP plants, mixtures of alkali nitrate salts are the preferred candidate fluids. These nitrate salts are widely available on the fertilizer market. Liquid thermophysical properties of typical mixtures are available in literature 3, 4.
Where can I find information about Tesis thermal energy storage plant?
Details of this plant can be found in literature 33, 34. DLR Test Facility for Thermal Energy Storage in Molten Salts (TESIS) in Köln, Germany. The commercial status of high-temperature TES makes CSP a unique application. By storing the thermal energy, CSP is able to firmly deliver electricity on demand.
What temperature does a steam storage system need to be discharged?
The storage is discharged with 103 °C feedwater. The outlet parameter as required by the customers is steam at 300 °C, as stated. The saturation temperature at the system pressure of 25 bar is about 224 °C; the steam in the steam mains is, therefore, superheated by at least 76 °C.
