CST with PCM thermal storage

Concentrated solar thermal coupled with PCM-rock bed thermal storage

A system designed to store excess heat generated by a Concentrated Solar Thermal (CST) source, that releases heat using low-cost filler materials and phase change materials (PCM).

About

A system designed to store excess heat generated by a Concentrated Solar Thermal (CST) source, that releases heat using low-cost filler materials and phase change materials (PCM).

Key Benefits

• Low cost thermal storage • Output temperature ranges 550-900 °C • Economically benefits industries where commercial rates for gas contract prices are above $12/GJ • Single tank storage system • PCM increases storage energy

Applications

The technology is ideal for pre-heating or high temperature applications such as: • Ore preheating • Copper refining • Calcination of limestone • Calcination of magnesia • Thermal treatment of mine waste
