RayGen's solar-hydro power plant consists of RayGen's proprietary PV Ultra, a concentrating photovoltaic solar co-generation tower, combined with its patented electro-thermal storage. The technology generates heat as a by-product which is captured and used for thermal storage. The electro-thermal storage system consists of an Organic Rankine Cycle (ORC) turbine, industrial chillers and two insulated water-based thermal storage pits or reservoirs, each roughly the size of four Olympic size swimming pools. One of the reservoirs is kept at a temperature of 90 degrees and the other at close to 0 degrees, and the temperature difference is used to generate dispatchable electricity using ORC turbines, according to RayGen.
The project builds on a feasibility study and development work supported by a $3 million ARENA grant in March 2020. ARENA also supported RayGen with $8.67 million in funding to develop and construct its 1-MW PV Ultra pilot project in Newbridge, Victoria. (Source: ARENA, PR, June, 2021)
