6 FAQs about [One ton of water energy storage]

What is energy storage volume?

The storage volume ranges from 2 to 4 ft3/ton-hour for ice systems, compared to 15 ft3/ton-hour for a chilled water. The application for energy storage systems varies by industry, and can include district cooling, data centers, combustion turbine plants, and the use of hot water TES systems.

What are thermal energy storage strategies?

There are two basic Thermal Energy Storage (TES) Strategies, latent heat systems and sensible heat systems. Stratification is used within the tank as a strategy for thermal layering of the stored water. Colder water is denser and will settle toward the bottom of the tank, while the warmer water will naturally seek to rise to the top.
