6 FAQs about [Molten salt energy storage solar power tower]

What is molten salt storage in concentrating solar power plants?

At the end of 2019 the worldwide power generation capacity from molten salt storage in concentrating solar power (CSP) plants was 21 GWh el. This article gives an overview of molten salt storage in CSP and new potential fields for decarbonization such as industrial processes, conventional power plants and electrical energy storage.

Are molten salt towers the next-generation technology for solar thermal power?

Mark Mehos, thermal systems group manager at the National Renewable Energy Laboratory (NREL), says molten salt towers akin to SolarReserve’s are “the next-generation technology” for solar thermal power. Plants without storage may never be able to compete with PV, says Mehos.

What salt is used in molten-salt power towers?

The analysis compares a molten-salt power tower configuration using direct storage of solar salt (60:40 wt% sodium nitrate: potassium nitrate) or single-component nitrate salts at 600 °C or alternative carbonate- or chloride-based salts at 650 °C.

How molten salts are used in solar power plants?

Most of the operational plants have integrated a storage unit using molten salts as the storage media, one uses combined steam/oil (Dahan Power Plant), another just steam (Khi Solar One) and one a ceramic heat sink (Jülich Solar Tower).

Can molten salts be used for thermal energy storage?

To optimize the utilization of CSP systems, particularly during periods of low or absent solar radiation, the integration of thermal energy storage (TES) systems using molten salts has become a prevailing strategy.

Can molten salt storage be used as a peaking power plant?

Drost proposed a coal fired peaking power plant using molten salt storage in 1990 112. Conventional power plant operation with a higher flexibility using TES was examined in research projects (e.g., BMWi funded projects FleGs 0327882 and FLEXI-TES 03ET7055).
