Batteries can store energy for export on demand - but economics typically limits storage capacity to 1 or 2 hours at rated power output.RayGen solar energy plants employ fields of autonomous heliostats (self-aligning mirrors) to concentrate solar energy onto high-efficiency liquid-cooled photovoltaic cells. The electrical energy is exported and/or used to run the plant. The heat energy is transferred to a large body of water located underground. When electricity demand is high, this heat is used to boil ammonia, which spins an expansion turbine, which drives a generator (similar to some geothermal energy plants). The ammonia gas is then re-condensed, using chilled water.A 3.0 MW / 50 MWh (17 hours storage at rated output) plant is already operating in Carwarp near Mildura, VIC.Multiple grid-scale plants are in the projects pipeline.
