The Aachen battery storage start-up for industrial, commercial, and network applications has completed its Series B funding round of 15 million euros. The round was once again led by Dutch deep-tech investor FORWARD.One as the lead investor. Other investors include existing partners such as Interzero, PT1, Helen Ventures, Daphni, Aurum Impact (Goldbeck family), as well as new investors like Fiege Ventures and Newberry Investments.
At the same time, the company is expanding and opening a new production site in Aachen, NRW. The new production facility "Voltfang Future Fab" offers significant growth potential and enables scaling up to 1 GWh with high-performance and energy-dense storage solutions. By expanding production capacities, enough battery storage is expected to roll off the production line by 2030 to replace the Weisweiler coal-fired power plant and strengthen Germany's industrial site, the company says.
Expanded Production Capacities
With the fresh capital, the company aims to significantly expand production capacities and provide an additional 250 megawatt-hours of green storage capacity in Europe by the end of 2026, thereby meeting the
strongly growing demand for large-scale storage systems. In parallel, the intelligent energy management system Venma will be further developed with AI functions. With the help of Venma, companies can maximize their self-consumption, reduce their electricity costs, and trade on the energy market.
Battery Factory at the e.GO Location
The move into the former production halls of the Aachen electric car manufacturer Next.e.GO with 6000 m² in the TRIWO Technology Park in NRW underscores the high demand from industrial, commercial, and large-scale storage sectors. While the company's produced storage capacity was 5 MWh in 2023, it increased to 20 MWh in 2024. With the scaling of its production, the provider can further reduce dependency on battery storage from China and other Asian countries. By using second-life and overproduced batteries from the European automotive industry, the company promotes the development of an independent and resilient battery industry in Germany and Europe.
Energy Storage Market Growing Strongly
The energy storage market in Germany is continuously growing strongly and forecasts from the Fraunhofer Institute underscore its
importance, the specialist states. By 2030, around 100 GWh and by 2045, around 180 GWh of electrical storage capacity will be needed. Another advantage of the location is the proximity to other innovative companies on site like Cylib, which also belong to the Battery Circle Aachen, and Black Semiconductor, a pioneer of the next chip technology. This creates synergies and supports the development of the technology site Aachen in the field of battery technology.
“The financing round is a direct response to the enormous order intake we recorded in Q1 of this year. The expansion of energy infrastructure is urgently needed both in Germany and in Europe. Europe is facing major challenges in energy supply to make itself resilient to external influences. We now need to create significantly more flexibility in the form of large battery storage systems. The doubling of our valuation within 6 months is a sign of the market’s confidence in the technological relevance and growth potential of Voltfang," explained David Oudsandji, CEO and co-founder of Voltfang.
Paul Pruijmboom,
partner at FORWARD.One, sees the company as exemplary of the investment strategy: a strong hardware product with an intelligent software core, he says. With powerful and European-based storage technology, the team is addressing one of the most pressing problems of our time, the energy transition.
"We are convinced that the local energy infrastructure in Europe is one of the most important pillars for European economic growth," Pruijmboom further states.
Jens Fiege, Co-CEO of the Fiege Group adds, Voltfang offers logistics companies what they need for the future: "a technologically convincing, ecologically sensible, and economically scalable solution". With the involvement, they want to not only provide capital but also bring in our infrastructure and expertise to jointly advance economic energy storage solutions for logistics, continues Fiege.
"The combination of circular economy, energy management, and scalable storage technology solves precisely the challenges facing the building sector and energy supply today. Voltfang is an important partner for us when it comes to thinking holistically about building and energy solutions,” underscores Jan-Hendrik Goldbeck, managing partner of
