About
Making 24/7 renewables a reality through thermal energy storage.
Empowering renewables through thermal energy storage.
MGA Thermal’s mission is to revolutionise the world’s renewable energy systems by developing novel materials, designing innovative technologies and delivering thermal energy storage solutions.
Our core technology is a newly invented type of thermal storage material, Miscibility Gap Alloys (MGA). These alloys can store a huge amount of energy as heat, in a safe and easy to use way.
In our storage solutions, modular blocks of MGA are stacked into insulated storage tanks, which can store energy for use in a range of applications – improving the electrical grid’s stability, residential and commercial space heating, industrial process/waste heat, and even electric vehicles. Our first focus though, is enabling intermittent renewable energy sources such as the sun and wind, to provide base load electricity to the grid.
Modular blocks of MGA are able to be stacked and scaled into thermal energy storage systems - storing hundreds to millions of kilowatt hours of energy.

Transforming Industrial Decarbonisation with Next-Generation Thermal Energy Storage
Energy storage pioneer MGA Thermal has secured an additional $5.7 million, bringing its recent funding round to $14 million and total funds raised to $28.8 million.
Returning investors Main Sequence, Melt Ventures, and new investor JEKARA reaffirmed their confidence in MGA’s Miscibility Gaps Alloy (MGA) Thermal Blocks—a breakthrough in industrial heat decarbonisation for sectors like mining, mineral processing, and manufacturing.
This latest investment will advance the commissioning and scale-up of MGA Thermal’s Thermal Energy Storage (TES) system to supply high-pressure, high-temperature clean steam, a resource essential for industrial processes.
By harnessing steam’s longstanding role in manufacturing, which currently accounts for 23% of Australia’s total energy demand, MGA Thermal aims to dramatically reduce CO₂ emissions. Their goal: to abate 30 million tonnes of CO₂ by 2030, the equivalent of more than two decades of commercial flights between Sydney and LA.
Following the demonstration unit’s initial commissioning phase, the MGA Thermal team made targeted enhancements, reinforcing the system’s performance and commercial viability. With strong investor backing, MGA Thermal remains at the forefront of large-scale renewable energy storage, pushing forward its mission to revolutionise clean energy and usher in a more sustainable industrial era.
