Storing concentrated solar thermal energy via ‘falling’ ceramic particles

From pv magazine Australia

Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) has harnessed sub-millimeter ceramic particles to store energy in a concentrated solar thermal system. Its pilot plant in the state of New South Wales has successfully reached temperatures of 803 C through this method.

The agency said the novel concept increases temperatures in the process from 500 C to 800 C, and possibly more than 1,000 C. This holds promise for decarbonizing heavy industry, which can require extreme heat for processing. It also overcomes some of the limitations of heat transfer fluids traditionally used in concentrated solar thermal (CST) technologies, said the CSIRO.
