April 2020: RayGen and Egesim announce strategic alliance

RayGen Resources Pty Ltd (RayGen) and Egesim Group (Egesim) have recently formalised a strategic alliance that that will include the engineering, procurement and supply of world-class Organic Rankine Cycle (ORC) systems with core Turboexpander technology from Atlas Copco Gas and Process for RayGen’s Solar Power Plant (‘solar hydro’) technology.

The first project under this alliance will be a fully dispatchable renewable energy facility delivering 4MW of solar generation and 3MW/50MWh (17 hours) of storage. RayGen is partnering with major Australian power utility AGL on the feasibility stage of the project. RayGen recently secured $3 million AUD funding from the Australian Renewable Energy Agency (ARENA) to advance the project to financial close in 2020. The project will be located in Carwarp, Australia.

Egesim and their partner Atlas Copco Gas and Process will work with RayGen to deliver the Organic Rankine Cycle (ORC) module of RayGen’s Solar Power Plant. With support from EPC partner, Egesim Group, Atlas Copco Gas and Process, have delivered over 400MW of ORC systems throughout the world.

Egesim CEO Mutlu Akar said: “Egesim with its partner Atlas Copco are very pleased to be able to work closely with RayGen to commercialise their new Solar Power Plant technology. Our cooperation includes R&D support and supply of the world-class AtlasCopco Turboexpander solution with EPC provided by Egesim group. We believe that RayGen’s technology, including the Atlas Copco/Egesim ORC system can be competitive with coal power, matching the reliability and cost at large scale.”

James T Reilly, General Manager of Atlas Copco Mafi-Trench Company LLC (a product company in the Atlas Copco Gas and Process Division) said: “RayGen’s technology represents an innovative application of Atlas Copco’s Turboexpander products to establish a world-leading renewable power generation solution.”

RayGen CEO Richard Payne said: “We are thrilled to announce our strategic alliance with Egesim and their partner Atlas Copco, two leaders of heat-to-power applications globally. With Egesim and Atlas Copco’s ORC solution, RayGen is able to deliver the economics of pumped hydro and the flexibility of batteries.”
