RayGen’s Technology
Reliable clean energy, available day and night
Adaptable and Customisable
RayGen’s power plant integrates multiple technologies to supply large industrial customers and the electricity grid.
The system can be independently sized and operated, meaning it is fully flexible and can operate almost anywhere. RayGen’s solar can be fed into the grid or used for behind-the-meter charging of the RayGen system.
Due to its design, the technology can be installed at various scales to meet specific needs around the world.
Field of Dreams
RayGen’s hi-tech solar matches traditional solar PV on cost, land area and output, enables heat capture and agrivoltaics, and transforms the solar supply chain.
Like solar PV, RayGen generates electricity using the photoelectric effect. We use tracking mirrors to focus sunlight on to a central receiver of photovoltaic modules.
These modules are almost 2,000x more powerful than traditional solar panels, withstanding almost 1,000 times the solar concentration and using cells which are almost twice as efficient. One third of the sunlight is converted into electricity, and two-thirds into heat (hot water at 90°C). RayGen’s modules contain no polysilicon.
The Role of Water
RayGen’s storage uses the world’s most abundant natural resource: water.
Two water pits – each to a depth of 15-20m and the size of a small farm dam – store energy as hot and cold water. The cold water pit is ‘charged’ using low-cost electricity and a standard ammonia-cycle chiller. The hot water is sourced from RayGen’s hi-tech solar or a heat pump. The pits are covered and insulated, meaning minimal water and heat loss.
When electricity is required from storage, the temperature difference drives an organic Rankine cycle (ORC) turbine. Ammonia, the working fluid in the turbine, is evaporated by the hot water to turn the turbine to generate electricity. The ammonia is then cooled and re-condensed by the cold water to go through the cycle again. No ammonia is consumed in the process. The ORC turbine drives a synchronous generator, which can operate as a synchronous condenser when de-coupled from the turbine.
