Our Mission

To deliver renewable energy technology with the power to transform world energy systems

What we offer?

Cost competitive, easy to construct, flexible, utility scale renewable energy power generation and storage technology, that can dispatch clean energy, on demand, 24 hours a day.

Vast Solar is an Australian company that has developed world-leading solar thermal storage technology, delivering low-cost renewable energy that is reliable, controllable and dispatchable. We are innovators in the field of concentrated solar thermal power (CSP). Since 2009 we have been inventing solutions to address the issues that have held back the adoption of CSP. Our CSP system, developed through fundamental research and elegant, cost effective engineering, sets new standards of price and performance.

Our Technology

Vast Solar’s CSP system is smart, modular and highly cost effective to construct and operate. Our technology includes novel heat collection and transfer technologies, along with integrated storage so that we can generate and then dispatch affordable renewable energy 24 hours a day. These features, along with advanced control systems, heliostat, tower and field design, uniquely position Vast Solar’s power technology within the CSP sector. Our elegant, clean, scalable power generation and storage system is competitive on performance and price not only with other renewable but also with fossil fuel power generation.

What drives us?

Ethical, professional determination and technical capability to deliver utility scale power generation with thermal storage. We make the cost of building CSP economic and we deliver new generation thermal storage so that renewable energy can be affordable and dispatchable. We are excited about sharing our technology with partners, energy providers and the communities they serve. We are proud to enable and help drive the change that we all need now – access to affordable, reliable, renewable energy.

How we do it?

We have developed and demonstrated technology for the world’s first modular CSP plant that uses liquid sodium as HTF at our 1MW CSP Pilot Plant. This plant was commissioned in June 2018. We develop CSP Plants and are currently working to develop a 50MW Solar Hybrid Plant (30MW CSP combined with 20MW PV). We partner with developers and utilities to configure scalable CSP plants that meet their unique market requirements. We bring our smart CSP engineering and design expertise coupled with our proven modular CSP approach and critical components. Vast Solar has developed a supply chain to deliver the critical components.

Low Cost, High Efficiency.

Cost

Modular array design utilises light weight and inexpensive materials. Prefabricated manufacturing techniques, robotic assembly and automated operating processes deliver rapid, low cost construction and enable cost effective ease of operation. Receiver maintenance is simple and does not require costly plant shutdowns.

Efficiency

Smart heliostat configuration in compact modular arrays maximises optical efficiency at rates higher than in central tower CSP plants. Proprietary distributed control over receivers enables the capture of more energy to realise higher operating temperatures to deliver greater power cycle efficiency.

Storage

The secret to Vast Solar’s highly efficient energy capture and storage system is the modularisation of solar collector arrays. The key enabler of this is the use of liquid sodium as the solar heat transfer fluid and Vast Solar is the clear world leader in the use of sodium for solar power applications.

Attractive Economic Profile

Vast Solar has developed world-leading solar thermal storage technology with a cost structure significantly lower than any currently available global competitor.

Partners and Associates

Vast Solar is a small private company with an appetite for growth.
