German firm gives 'second life' to used EV batteries
Voltfang's facility refurbishes used EV batteries into large stationary storage systems to support Germany's renewable energy goals and circular economy efforts.
- The German company Voltfang opened its first industrial site this week in Aachen to repurpose used electric vehicle batteries for energy storage.
- Established in 2020 by a trio of engineering students, Voltfang plans to manufacture battery systems with an annual storage capacity of one gigawatt-hour by 2030 to contribute to Germany’s energy transition.
- Technicians at Voltfang test the used EV batteries to assess lifespan and refurbish those in good condition, stacking them inside fridge-size cabinets that store excess solar and wind power.
- By the end of 2024, Germany had installed approximately six gigawatt-hours of stationary storage capacity, more than doubling the 2.5 GWh recorded in 2022, as renewable energy sources accounted for close to 60 percent of the country’s electricity generation last year.
- Despite hurdles including a small supply of used batteries, CEO David Oudsandji said Voltfang hopes to achieve profitability soon while helping reduce dependence on fossil fuels and increase renewable use.
