Altech Batteries (ASX:ATC) secures €46.11M German grant for CERENERGY® project

Altech Batteries has reached a material milestone in the development of its CERENERGY® Sodium Chloride Solid State battery project in Germany, securing conditional binding funding approval of up to €46.11M under Germany’s federal STARK economic development program.

The approval represents a meaningful step toward construction of the planned facility in Saxony and confirms the project’s progression through a key stage of the German government funding process.

Highlights

• Conditional binding funding approval of up to €46.11M under Germany’s STARK program.

• Grant covers approximately 30% of eligible project CAPEX.

• Funding is conditional on achieving full project financial close by 30 June 2026 and parliamentary approval of funds under Germany’s 2026 Federal Budget.

• Approval supports progression toward construction of a planned 120 MWh CERENERGY® battery manufacturing facility in Saxony, Germany.

The funding approval, granted to Altech Batteries GmbH for the CERENERGY® Sodium Chloride Solid State battery project, marks the successful completion of the second and decisive stage of the STARK program assessment process.

The STARK program is supported by the German Federal Ministry for Economic Affairs and Energy in cooperation with the EU and is intended to support regions undergoing structural change through investment in ecologically, economically and socially sustainable projects.

From a funding perspective, the grant is structured to cover approximately 30% of eligible investment costs, with the approved amount capped at €46.11M.

While the approval is binding, it remains conditional on the project reaching full financial close by 30 June 2026 and on parliamentary approval of the funding allocation as part of Germany’s 2026 Federal Budget.

These conditions are customary for projects of this scale within the German federal funding framework.

The CERENERGY® project is focused on the development and commercialisation of a Sodium Chloride Solid State battery technology being advanced in collaboration with the Fraunhofer Society.

The technology is positioned by the company as a safe and sustainable alternative to lithium ion batteries and is intended for stationary energy storage applications, particularly within the European market.

The planned manufacturing facility in Saxony is designed with an annual production capacity of 120 MWh.

Management has described the funding approval as a significant step in reducing project risk and advancing the project toward execution. As Managing Director and Chief Executive Officer Daniel Raihani commented,

“Securing conditional binding funding approval of up to €46.11 million under Germany’s STARK program is a major milestone for the CERENERGY® project. The support reflects the strategic importance of establishing advanced, non lithium energy storage manufacturing capability in Europe and recognises the technical progress achieved to date in collaboration with Fraunhofer IKTS.”

The company has also emphasised the impact of the grant on the project’s capital structure, noting that the funding materially de risks the project by covering approximately 30% of eligible investment costs.

This funding support provides a stronger foundation as Altech Batteries progresses toward full project financing and construction of the planned facility in Saxony.

Looking ahead, Altech remains focused on completing financial close by mid 2026 and advancing the CERENERGY® technology toward commercial deployment.

The conditional grant approval provides a defined pathway for the next phase of development and positions the project within Germany’s broader policy objective of supporting sustainable industrial transformation and advanced energy storage manufacturing.
