Graphite storage technology

The VirtualSolarTM solar thermal energy storage technology, is capable of storing high grade heat at up to 800C, on demand and 24 hours a day!

The system operates by placing the VirtualSolarTM block receiver containing 10 tonnes of graphite on a 24m tower and surrounding it below with mirrors know as heliostats. Using           custom designed software, the heliostats follow the path of the sun and direct its rays onto the graphite. The heat is extracted from the graphite on demand and can be converted to steam, whilst the sun’s rays are still being directed onto the graphite or after the receiver is sealed at night.
