6 FAQs about [Liquid sodium solar power plant]
Can liquid sodium be used in a solar power plant?
The compatibility of liquid sodium with structural metal alloys, ceramics, supercritical carbon dioxide, and molten salts has been reviewed for applications in advanced solar thermal power plant systems. Satisfactory performance of structural alloys in liquid sodium systems was found to depend on a variety of factors, as summarized in Table 1.
Why do solar power plants use molten nitrate salts?
State-of-the-art solar power plants often use molten nitrate salts as heat transfer fluid. The use of liquid sodium instead leads to lower electricity generation costs. Sodium has a high thermal conductivity and thus large heat transfer rates are possible. Hence, a smaller absorber surface is sufficient for the same thermal power.
Could molten salt be used in concentrated solar power plants?
Molten salt storage in concentrated solar power plants could meet the electricity-on-demand role of coal and gas, allowing more old, fossil fuel plants to retire.

Could molten salt save solar energy?
But now, a new venture called SolarReserve hopes to change all that using salt! Their program would save and store captured solar energy in molten salt, the new solar plant will produce up to 500 megawatts of peak power — comparable to what a regular coal power plant can produce, only with no greenhouse gas emissions.
Can molten salt power Las Vegas?
Pillar Of Salt: More than a million square meters of mirrors focus on a tower of molten salt to generate power for the Las Vegas Strip. Solar power projects intended to turn solar heat into steam to generate electricity have struggled to compete amid tumbling prices for solar energy from solid-state photovoltaic (PV) panels.
Why is molten salt used in solar power towers?
The study states, “molten salt is used in solar power tower systems because it is liquid at atmosphere pressure, it provides an efficient, low-cost medium in which to store thermal energy, its operating temperatures are compatible with today’s high-pressure and high-temperature steam turbines, and it is non-flammable and nontoxic.”
