LAVA Power – Turning heat into zero emission electricity. The world's most efficient heat engine transforms heat into zero-emission electricity at near-perfect efficiency.
During the hours of solar insolation, the excess thermal energy can be stored in a TESS, which can be retrieved for electricity production during off-sun hours. Thermal energy can be stored in three different ways: sensible heat storage (SHS), latent heat storage (LHS), and thermochemical energy storage (TCES) .
Thermal energy is stored as sensible heat in storage material by increasing its internal energy (i.e., change of temperature of storage media). Energy storage capacity depends on specific heat of storage material and its allowable temperature increase.
However, sensible heat storage requires in general large volumes because of its low energy density, which is 3 and 5 times lower than that of PCM and TCS systems, respectively. Furthermore, sensible heat storage systems require proper design to discharge thermal energy at constant temperature.
Thermal energy storage in the form of sensible heat relies on the specific heat and the thermal capacity of a storage medium, which is usually kept in storage tanks with high thermal insulation. The most popular and commercial heat storage medium is water, with a number of residential and industrial applications.
