The project will be built in two phases: 50 MW in 2018 and 150 MW with latent heat storage. There are three forms to store heat: latent, sensible, and thermochemical. The latent heat storage uses the process of melting or crystallizing a material known as Phase Change Material (PCM). Cleanergy believes that it will be essential for all renewable technologies to be equipped with energy storage as penetration of renewable energy increases in the grid. “For CSP specifically, the competitiveness against PV hinges on a more efficient solution for delivery of dispatched energy,” commented Jonas Eklind, president and CEO of Cleanergy.

Aalborg CSP, another CSP provider, made a joint development agreement with SaltX Technology to offer cost-effective, fully-scalable, and dispatchable renewable energy solutions. Based in Sweden, SaltX has invented a patented technology to store thermal energy with salt.
“EnerStore, SaltX’s large-scale storage, is a thermochemical storage, which chemically holds the thermal energy in the salt so that the temperature 500 degree Celsius can be taken out at the same level without maintenance heating and with no or marginal heat losses,” explained Karl Bohman, CEO of SaltX Technology. “In addition, the EnerStore material, with the nano-coating, does not corrode as opposed to molten salt. It is non-toxic and can be recycled at the end of its life cycle.”
Eklind’s comment echoed this. “In order to compete with PV, the storage component in CSP is critical,” he said...Read More Here
