"Australian solar innovator RayGen has successfully deployed its unique
technology using concentrated solar power to produce and store both clean
electricity and thermal energy in a first international project in Brazil.
Located at a demonstration site in Brazil operated by AXIA Energia, formerly
known as Eletrobras, the 1-megawatt (MW) PV Ultra system consists of a
heliostat field, receiver tower, PV Ultra modules, and plant control system.
In addition to being able to feed solar electricity directly to the grid,
RayGen’s PV Ultra is also able to store energy as cold and hot water in two
water pits.
The cold water pit is “charged” using electricity and a standard ammonia-cycle
chiller, while the hot water is sourced from RayGen’s solar system or a heat
pump. When electricity is required, the temperature difference between the two
water pits drives an organic Rankine cycle (ORC) turbine."
