Project
MGA Demonstration Plant
In April 2025, MGA Thermal commissioned a first-of-its-kind steam‑integrated thermal battery at its Tomago facility in Australia. This 5 MWh demonstration plant was a key milestone in the commercialisation of MGA Thermal’s next-generation technology, proving that renewable energy can be stored and dispatched as high-grade process heat - reliably, affordably, and at scale. This project received $3.75m from ARENA.
