Continuous, carbon-free energy for the world.

Vast Solar is a world leader in solar thermal technology, that can produce electricity overnight.

Solar thermal has a critical role to play in the energy transition.

The world needs to repower, to get away from burning fossil fuels, and Vast Solar’s solar thermal storage technology will play a critical part in this transition. Our innovative modular tower solar array combines the best elements of molten salt towers and parabolic trough systems to deliver the world’s lowest-cost dispatchable, renewable energy for hot, dry climates.

What do we do? Our CSP technology delivers utility scale renewable energy generation with scalable, thermal storage. This delivers the ability to generate renewable energy during the day and to dispatch renewable energy 24 hours – during the day and night. By helping re-engineer the future of large scale energy storage, Vast Solar’s technology will help resolve intermittency challenges associated with variable renewable energy sources (VRES) as they deliver increasingly more ‘bulk’ renewable energy to the world’s power grids.

How? By delivering flexible, modular concentrated solar thermal power (CSP) technology with high optical and thermal performance and affordable, scalable thermal storage.

Why? To help solve the problem of burning fossil fuels. To provide affordable storage to address the VRES intermittency challenge. So more people can access dispatchable renewable energy on demand, 24 hours a day … affordably, reliably, simply.

Low Cost, Carbon Free, Dispatchable Energy

Vast Solar’s solar thermal technology is the missing piece in the energy puzzle. Alongside solar PV + batteries, pumped hydro energy storage and green hydrogen, CSP is a critical part of the integrated mix of complementary energy storage and generation technologies that will meet Australia’s future energy needs.

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.

Vast Solar LETS 2022 Submission

The Federal Government’s Technology Investment Roadmap, together with the supporting and annually updated Low Emissions Technology Statement (LETS), recognises the importance of dispatchable renewable energy storage in Australia’s future energy mix. The LETS identifies long duration renewable energy storage, dispatched at less than $100/MWh, as a key investment priority.
