Through its 2022-23 Budget process, the Australian Government agreed to negotiate with Vast Solar the terms of concessional finance of up to $110 million to support the development of a 30MW CSP project.
On April 29, Vast Solar announced it had Australian Government backing to build a concentrated solar thermal power (CSP) plant in Port Augusta, South Australia.
Vast Solar’s CSP takes the sun’s energy during the day, and delivers it at night.
Vast Solar’s innovation journey since 2009 has been to develop an economically viable design for concentrating solar thermal power (CSP) that harnesses the superb thermal characteristics of sodium as a heat transfer fluid (HTF).
Sodium’s use as a HTF makes modular arrays possible. Modular arrays capture more energy per m2 of mirror, offer control benefits that improve performance and reduce risk, are cheaper, can be constructed faster and they can be configured to meet business needs.
Higher and more consistent outlet temperatures deliver better performance through increased energy capture and a reduction of risks associated with thermal fatigue.
Importantly, the molten salt in a Vast Solar power plant is never exposed to temperatures sufficient to cause it damage.
Over ten years, Vast Solar has designed, prototyped and tested components and plants to confirm these economic and operational advantages.
Vast Solar’s patented and proprietary CSP system is now available for commercial deployment.
