Sunrise CSP - Efficient Energy Storage Solution

Sunrise CSP offers Pressurised Hot Water storage solutions for process heat applications needing temperatures up to 400oC, e.g. space heating/cooling, institutional cooking & laundry, hot water supply, sterilization, food/diary processing, refrigeration.

These storage systems use the high-temperature output of Big Dishes, typically at 500oC, to efficiently charge the storage. When steam is required then steam is generated from storage using a flash tank or heat exchanger.

The system can also be used for producing hot air using a steam-to-air heat exchanger.

Sunrise CSP is developing a thermal oil Receiver-Storage-Steam generation system that will heat thermal oil directly in the Receiver and store that oil in a tank at up to 450oC. When steam or hot air is required then it is generated from storage using an oil-to-steam / air heat exchanger.

The advantage of this system the ability to heat and store oil at atmospheric pressure and does fall under pressure vessel and boiler codes.

Sunrise CSP has developed a unique approach to molten salt energy storage that is ideally suited to the high steam temperatures that the Big Dish achieves. SUMO is specifically designed to support the requirement for dispatchable electricity generation using state-of-the-art steam turbines with capacities of tens to hundreds of megawatts.

SUMO allows high-temperature energy transportation from a Big Dish solar field to an industry-standard molten salt thermal storage system allowing molten salt temperatures up-to 600oC, with higher temperatures to be available in the future as salt media develops.

Sunrise CSP owns the patent for the SUMO superheated steam transport process.

Sunrise CSP has partnered with a German company for the integration of Metal Hydride storage where hydrogen is used as a heat carrier.

The technology is proven at pilot scale and Sunrise CSP is collaborating on scaling up to commercial scale using our Big Dish.
