Suunpower, a CSP developer and Engineering Procurement Contractor (EPC) , has signed a partnership agreement with Norway’s EnergyNest to deploy thermal energy storage (TES) systems in China.

Suunpower is involved in the construction of China’s first 20 CSP projects for a total capacity of 1 GW.

The EnergyNest TES has «significant cost advantages over molten salt energy storage systems for new CSP projects,» the company said in a statement.

The EnergyNest system allows plants to capture waste heat from industrial facilities and applications include industrial waste heat recovery and smart power grid solutions, such as storing and utilizing excess renewable energy.

The EnergyNest technology will allow Suunpower to expand its product portfolio, the Chinese company said.
