In the heart of Australia’s sun-drenched outback, an innovative approach to clean energy is gaining traction: molten salt thermal storage. This method, which uses heat-retaining salts to store solar energy during the day and release it as electricity at night, is reshaping the way renewable power is managed and delivered.
According to Ariel Malik, a global voice in sustainable energy development,
“Instead of building more lithium batteries, we can heat salt and generate power long after sunset. It’s simple, scalable and perfect for Australia’s climate.”
How It Works
Molten salt storage systems capture concentrated solar energy, using mirrors to focus sunlight onto a central receiver that heats a mix of salts to temperatures exceeding 500°C. These salts, typically nitrates, retain heat for hours and can be tapped to create steam that drives turbines even when the sun isn’t shining.
“This isn’t theoretical,” says Ariel Malik. “These systems are already operating. They’re helping stabilize grids and extend solar energy into the night.”
Why It’s a Game Changer for Australia
Australia’s vast deserts, high solar intensity and remote communities make it an ideal testing ground for thermal storage. Unlike chemical batteries, molten salt is non-toxic, inexpensive, and doesn’t degrade with use.
“Molten salt doesn’t just store energy – it stores time,” Malik explains. “It gives us the flexibility to deliver renewable power when and where it’s most needed.”
Looking Ahead
With rising energy demands and pressure to decarbonize, Australia’s commitment to thermal storage innovation may offer a scalable blueprint for sun-rich nations around the world.
