Masdar Institute of Science and Technology and Cleanergy have signed a service agreement to jointly engage in research on solutions for a Thermal Energy Storage (TES) system to integrate with Cleanergy's Concentrating Solar Power (CSP) Stirling-based solar electricity technology. Cleanergy and Masdar Institute will under the agreement conduct research and development to determine the optimal TES material to achieve dispatchable solar electricity with the Stirling CSP system. The development of a reliable and highly efficient TES and its integration with the Stirling CSP system is of key importance for the product. It is believed that this storage solution combined with Cleanergy´s highly efficient Stirling engines will produce scalable and dispatchable renewable electricity at very competitive cost, due to the system's modular design.
