Acciona Solar, under the Thermal Storage FOA, plans to develop a prototype thermal energy storage (TES) module with high efficiency. This project is looking at a packed or structured bed TES tank with molten salt flowing through it.

Approach

Under this award, Acciona is aiming to design and validate a sensible heat TES module with round-trip efficiency >93%. The module will serve as the building block of a TES system that can be deployed at costs in line with the DOE 2020 goals.

Innovation

The goal of the prototype design is to eliminate the need for heat tracing along a parabolic trough system that is capable of operating at a temperature of at least 500°C.
