What they do.

MGA Thermal stores renewable electricity as heat in patented metal-alloy blocks. The blocks act as industrial batteries for heat. They charge from electricity, hold heat for hours or days, and release it on demand at process temperatures. Factories can switch to renewable energy without replacing their existing thermal equipment.

The blocks use a miscibility-gap-alloy formulation built around common metals. They are durable, non-toxic, and stable across thousands of charge cycles. The company is targeting capacities at megawatt-hour to gigawatt-hour scale.

Why it matters.

Industrial heat accounts for roughly 20% of global energy demand and a comparable share of emissions. Factories burn gas, coal, and oil for process heat because electrochemical batteries cannot deliver high-temperature heat economically. Without a workable thermal-storage option, industrial decarbonisation stalls regardless of how clean the grid becomes.

Thermal storage closes that gap. Cheap renewable electricity charges the blocks when wind and solar are abundant. Factories draw heat on demand around the clock. The economics work because thermal storage is cheaper per kilowatt-hour than electrochemical batteries at industrial duty cycles.

Where they are now.

  • April 2025, MGA Thermal opened its first Electric Thermal Energy Storage demonstration plant, validating block performance at commercial scale.
  • Series A complete.
  • Engaging industrial customers across Australia, Europe, and North America for early commercial deployments.
  • Capital deployment supports block manufacturing capacity, demonstration projects, and customer-facing engineering.

The CVCF investment.

Climate Fund 1 backed MGA Thermal as a founding portfolio company. Industrial heat is the largest underserved decarbonisation market. The company that wins on thermal-storage chemistry wins on the unit economics, and MGA's alloy formulation has the cost, density, and durability profile the market needs. Decarbonisation is the consequence of commercial fit.

MGA Thermal passed the Climate Impact Committee's IRIS+ review. Each megawatt-hour of storage capacity deployed displaces a measurable quantity of fossil-fuel combustion, tied directly to the company's commercial output.
