Sulamolämpövarastoint

Sulamolämpövarastoint, also known as molten salt thermal energy storage, is a technology used to store thermal energy in a molten salt mixture. This process involves heating a salt compound to its melting point, at which point it becomes a liquid and can absorb and store a significant amount of heat. When energy is needed, the molten salt can be cooled, releasing the stored heat.

The primary application of sulamolämpövarastoint is in conjunction with concentrated solar power (CSP) plants. In CSP systems, mirrors concentrate sunlight to heat a fluid, which then transfers its heat to the molten salt. This heated salt is stored in large insulated tanks. The stored heat can then be used to generate steam, which drives turbines to produce electricity, even when the sun is not shining. This allows CSP plants to provide a more consistent and dispatchable power output.

Molten salt mixtures, often composed of nitrates like sodium nitrate and potassium nitrate, are chosen for their high specific heat capacity and thermal stability at elevated temperatures. They also have a relatively low cost and are non-flammable, making them a safe and efficient storage medium. The design of the storage system involves insulated tanks to minimize heat loss and a pumping system to circulate the molten salt between the heat source, the storage tanks, and the heat exchanger. Sulamolämpövarastoint offers a viable solution for grid-scale energy storage, contributing to the integration of renewable energy sources into the power grid.
