EIB supports VoltStorage technology to store wind and solar energy

  • VoltStorage develops ecological energy storage systems that store power from renewable energy, potentially overcoming dependency on sun shining and wind blowing.
  • The EIB has granted a venture debt loan of €30 million to be invested in research, development and innovation, as well as a new factory.
  • The loan is guaranteed by the European Commission’s research and innovation programme.

Munich, July 28 2023 - The European Investment Bank (EIB) is financing Munich-based VoltStorage  GmbH with a venture debt loan of €30 million. The aim is to co-finance the development and commercialisation of innovative Vanadium redox flow battery for commercial and agricultural businesses and scale up the new Iron-Salt-Battery-technology (ISB).

With the development of the ISB, VoltStorage is setting standards in the field of long duration energy storage, offering wind and solar farms a highly cost-effective and resource-saving option for bridging supply gaps during periods of low wind and sun and for ensuring base load capability. This could eventually make renewable energy as independent from weather conditions as fossil fuel power plants.

The technology has the potential to become a game changer for the green transition towards renewable energies. That is why this EIB loan is backed by the European Union’s InnovFin Energy Demonstration Projects (EDP) Facility.

VoltStorage plans to bring ISB technology to utility scale from 2025 onwards. Founded in 2016, the company aims to make renewable energy available around the clock using sustainable batteries. In contrast to the lithium or cobalt used in today’s car batteries, iron and salt are common raw materials that are easily obtained. And while for car batteries, short charging cycles are crucial, long duration energy storage systems are specifically developed for longer charging and discharging periods to bridge power generation gaps of up to 100 hours and ensure the provision of base load.

EIB Vice-President Ambroise Fayolle, who is responsible for activities in Germany, highlighted, “The EIB supports innovative and sustainable advanced technology developed and manufactured in the European Union, and especially storage technology. VoltStorage’s technology has the potential to become a game changer for renewable energies, making them as reliable 24/7 as fossil fuel power plants have been in the past. We are therefore proud to support this promising start-up.”

Jakob Bitner, CEO & Co-Founder of VoltStorage, remarked, “We are thrilled to have the support of the EIB in our mission to provide cost-effective and sustainable energy storage solutions for businesses and communities around the world. This financing will enable us to fully focus on developing and commercialising our innovative energy storage solutions, as well as scaling up our production capabilities to meet growing demand. This will accelerate our mission of making renewable energy available 24/7 with sustainable batteries and contribute to the transition towards a more sustainable and resilient energy future.”


Background information

The EIB is the long-term lending institution of the European Union, owned by its Member States. It makes long-term finance available for sound investment in order to contribute towards EU policy goals. The EIB`s activities focus on the following priority areas: climate and environment, development, innovation and skills, small and medium-sized businesses, infrastructure and cohesion. The EIB works closely with other EU institutions to foster European integration, promote EU development and support EU policies in over 140 countries around the world.

The InnovFin Energy Demonstration Projects (EDP) Facility provides loans, loan guarantees and equity-type financing (typically between €7.5 million and €75 million) to innovative demonstration projects in the field of energy system transformation — including but not limited to renewable energy technologies, smart energy systems, energy storage, and carbon capture utilisation and storage. Target projects may relate to innovative energy system assets, manufacturing processes or services and, on a pilot basis, other means of supporting circular economy. The products are guaranteed by the EU research and innovation programme Horizon 2020 and deployed by the Bank.

VoltStorage GmbH develops and produces energy storage systems based on ecological redox flow technology. With its sustainable storage solutions, VoltStorage strives to achieve its vision of making 100% renewable energy available 24/7. With redox flow technology, VoltStorage is establishing a mass-market alternative to lithium-based storage technologies that does not require rare materials or conflict minerals, is fully recyclable, and also has high operational reliability and durability. For a fairer and cleaner world, for generations to come.
