Voltfang receives €5 million funding for production of sustainable energy storage systems

Voltfang provides a solution to both the battery recycling problem and the energy transition with its high-quality energy storage systems made from used electric vehicle batteries. The Aachen-based startup enables the reuse of EV batteries through a specially developed AI-based software that evaluates battery longevity. We give the battery a second life in stationary operations. With the help of our operating systems and continuous monitoring, we can make our batteries just as durable as new batteries. We guarantee this with our 10-year Batteryflat," says David Oudsandji, Co-CEO of Voltfang. The company has already conducted several successful pilot projects in Germany and has won major customers such as ALDI Nord and Schaltbau. 

"In ten years, there will be no new batteries in the commercial sector," says Roman Alberti, Co-CEO of Voltfang. This is not only about the sustainable recycling of batteries but also about saving on material imports and, above all, costs. "With the help of our energy management system, our storage systems can be intelligently deployed, allowing the battery to be amortized as quickly as possible," explains Roman Alberti. 

"We can connect urgently needed capacities to the grid in the coming years to ensure grid stability. This is not only an advantage for our customers but for anyone who wants to avoid blackouts," explains Afshin Doostdar, CTO of Voltfang. "The grids are not designed for the energy transition. Electric mobility, heat pumps, and fluctuating renewable energies require cost-effective and sustainable intermediate storage solutions that can be deployed in the short term. With our energy storage systems, we achieve this and reach a milestone in addressing the fundamental challenges of the energy transition." 

Voltfang was founded in 2021 and has already brought a certified and market-ready product to market. As a spin-off from RWTH Aachen, the startup now employs 50 people and operates a production site in Aachen. Voltfang aims to deliver more than 40 MWh of storage capacity in its products by the end of 2024. 

Fabian Heilemann (AENU): Stationary battery storage systems will play a central role in the energy system of the future by aligning electricity generation and consumption over time. Since Voltfang’s energy storage systems are made from reused electric vehicle batteries, they not only contribute to the energy transition but also reduce dependence on and consumption of resources compared to the production of new batteries. With their academic and practical expertise, the Voltfang team has the optimal DNA to build a European champion in the field of second-life batteries. 

Niko Samios (PT1): "There is no question that the market opportunity for energy storage will be enormous in the coming years. Sustainable energy production is becoming increasingly affordable, but it needs to be stored somewhere due to the grid structure, and decentralization is the best approach. Future regulatory requirements will further emphasize this process. Voltfang offers the most interesting product in this field that we have seen because they combine a cost advantage with a sustainability bonus."
