Revolta AG secures funding for sodium-ion home battery targeting solar households

German startup receives public funding for grid-compatible sodium-ion storage system

Revolta AG secured €660,545 from the German state of Hesse’s European Regional Development Fund (ERDF) for its 'Highly Efficient AC Salt Battery' project, with additional €124,940 from Germany’s Federal Environmental Foundation. The project runs from August 2026 to December 2029. German grid regulators implemented rules effective October 2026 that reduce levies and fees for storage systems drawing power from the grid and feeding it back later. Revolta launched a high-voltage sodium-ion home battery for households with photovoltaic systems in July (year unspecified). This system operates within the framework of time-of-use pricing mechanisms that could lower costs for solar users, but the source does not specify battery capacity, price, or exact launch year. The project’s timeline and funding amounts remain subject to Hesse’s final approval processes. The source is brief on implementation details and future impact, with no claims about non-solar households benefiting from this technology.
