Revolta wins €264,000 EU grant for grid-charging sodium-ion home battery
What's the deal? Revolta TechnologyDealroom has a profile for this one. Try Dealroom → has secured a €264,000 ($295,697) grant from the European Regional Development Fund (ERDF) and the German state of HesseDealroom has a profile for this one. Try Dealroom → to develop a plug-and-play sodium-ion battery for households. The system is designed to charge from the grid when power prices are low and feed electricity back when prices rise.
What's the endgame? The Frankfurt-based startup is targeting smaller rental apartments without their own solar panels, which have had limited options for battery storage. Its cells require no lithium or cobalt.
By the numbers: Hesse's register lists the "Highly Efficient AC Salt Battery" project with eligible costs of €660,545 and a 40% EU co-financing rate. The grant runs from August 1, 2026 to December 31, 2029.
Why now? Germany's grid regulator adopted rules on October 1 that let storage systems draw power from the grid and feed it back later, with lower levies and grid fees on returned power. The rules also cover storage without its own generation, strengthening the case for grid-charging home batteries.
Revolta launched a high-voltage sodium-ion home battery for households with solar in July. It also holds a €124,940 grant from Germany's Federal Environmental FoundationDealroom has a profile for this one. Try Dealroom → for an AC battery project running from September 2025 to September 2027.
The signal: The ERDF is backing sodium-ion technology across Germany. Moll BatterienDealroom has a profile for this one. Try Dealroom → secured €22.17 million in public funding — including €2.52 million from the ERDF — for a planned 1 GWh sodium-ion plant in Bavaria, pointing to a wider push toward lithium-free storage.
