Solar molten salt thermal energy generation
The molten salt circulates from the tower to a storage tank, where it is then used to produce steam and generate electricity. Excess thermal energy is stored in the molten salt and could be used to generate power for up to ten hours, including during the evening hours and when direct sunlight is not available. [ 5 ] .
The Crescent Dunes Solar Energy Project is aproject with an installed capacity of 110(MW)and 1.1 gigawatt-hours of energy storagelocated near , about 190 miles (310 km) northwest of.
The project'swas , which carried out the engineering design, procured the equipment and materials necessary, and then constructed and delivered the facility to Tonopah Solar Energy. The project includes 10,347that.
• 2012 January – The solar tower under construction as seen from a commercial airliner. The eponymous Crescent Dunes are at lower right. • 2014 December – Completed site as seen from a commercial airliner. .
In late September 2011 Tonopah Solar Energy received a $737 millionfrom the(DOE) and the right to build on public land. The capital stack included $170,000,000 ininvestment through.
Crescent Dunes began operation in September 2015,but went off-line in October 2016 due to a leak in a molten salt tank. It returned to operation in July 2017.While its average monthly production was expected to exceed 40,000 .

Completed the TES system modeling and two novel changes were recommended (1) use of molten salt as a HTF through the solar trough field, and (2) use the salt to not only create steam but also to preheat the condensed feed water for Rankine cycle.
The article gives an overview of molten salt thermal energy storage (TES) at commercial and research level for different applications. Large-scale molten salt storage is a commercial technology in the concentrating solar power (CSP) application.
Molten salt’s physical and thermal properties make it a particularly good candidate for energy storage.
Molten salts could be replaced by nanofluids soon after nanofluids technology TRL scales up; they show an increase on the specific heat and the thermal conductivity than the base fluid molten salt. Many challenges must be address before this happens agglomeration, stability, etc.
