Battery Day 2026: From Innovation to Industry
During Battery Day in Den Bosch, it became clear that batteries are no longer just a technological innovation, but a strategic pillar for Europe’s energy self-sufficiency and defense. A key moment was the presentation of the new Battery Systems Action Agenda, which sets the course for the coming years in the area of European production of BESS systems and crucial components such as anodes, as well as the pursuit of self-sufficiency in critical raw materials.
European Cooperation on Battery Production
During the event, a new Dutch-German call for innovation was also announced for the development of next-generation battery cell production. A total of €3 million has been made available for the program on both sides of the border. The call specifically targets Dutch and German consortia and is intended to contribute to scaling up new battery technologies from research to industrial production. ESNL views this as an important first step, but more will be needed to truly get this production off the ground.
A recurring theme during Battery Day was that Europe is technologically strong but struggles to produce innovations on a large scale. Several speakers pointed out that research and development are in good shape, while the transition to commercial production, in particular, entails financing risks. Many stakeholders view risk reduction through public-private de-risking instruments as crucial to actually keeping European innovations in Europe and scaling them up. The evaluation of the Action Agenda also shows that the greatest challenge no longer lies in R&D, but in the transition from the laboratory to industrial production.
Batteries as a Strategic Technology
One of the keynote speakers emphasized that batteries now touch on virtually all societal challenges. Due to international tensions, there is a growing need for a European supply chain for batteries and battery materials. The heavy reliance on raw materials, components, and production capacity from China is increasingly viewed as a strategic risk. The action agenda presented therefore places a strong emphasis on strengthening the European battery value chain, with a particular focus on innovative materials, production processes, and circular solutions.
New Opportunities for Dutch Industry
During various presentations, it was emphasized that the Netherlands should not try to copy China by building large-scale gigafactories. Opportunities for the Netherlands lie precisely in areas such as new battery materials, high-quality production technology, and Long Duration Energy Storage (LDES). The evaluation of the Action Agenda shows that the Netherlands has already established a strong international position in the fields of innovative anodes, battery equipment, and battery research.
In addition, attention was drawn to the important role that the Dutch high-tech industry can play. Companies in sectors such as semiconductors and precision technology possess knowledge and expertise that are directly applicable to battery production. This, too, is a key building block of the new action agenda.
Defense as a Driving Force
The focus on defense was particularly notable. Electrification and energy storage are becoming increasingly important for military applications, ranging from drones to mobile energy systems. As a result, the defense sector is not only becoming a user of battery technology but can also serve as the primary customer for innovative European solutions. According to several speakers, this offers opportunities to bring new technologies to market more quickly while simultaneously strengthening Europe’s strategic autonomy.
Action Plan as an Important Step Forward
For Energy Storage NL, the action plan presented is a valuable step forward, as also mentioned in Energeia. In particular, the focus on innovation, industrialization, and strengthening the European supply chain aligns well with the challenges facing the battery sector.
At the same time, Energy Storage NL emphasizes that the existing Dutch energy storage market also requires attention. While the Action Agenda focuses primarily on the development of future battery technologies and production capacity, the Comprehensive Energy Storage Policy Agenda will be made public in mid-October. This agenda is intended to provide solutions to the bottlenecks facing the current storage market, such as high grid tariffs, permitting, grid congestion, and the associated contract types for large-scale energy storage. Storage is something the energy system desperately needs right now to store renewable energy, keep the grid balanced, and prevent grid congestion.
According to ESNL, the combination of a strong innovation agenda for battery production and a policy agenda for the further rollout of energy storage in the Netherlands forms an important foundation for further strengthening both the industry and the energy transition. ESNL would like to see more intensive collaboration during the implementation of both agendas.
