The merged entity will develop and commercialise the technology, with VDL Groep serving as the stack manufacturing partner.
The new company aims to be the first to launch a fully flexible electrolyser with a capacity of up to 15 MW. Powered by solar or wind energy, the system will be capable of producing approximately 300 kg of hydrogen per hour. Pilot projects with industrial customers are already under way, with full-scale demonstrations and commercial ramp-up to follow.
Both VDL Hydrogen Systems and Battolyser Systems are developing next-generation pressurised alkaline electrolysers. VDL Hydrogen Systems has focused on high-capacity designs, while Battolyser Systems has prioritised operational flexibility to minimise the cost of hydrogen production. The merger is expected to significantly enhance product competitiveness and the ability to deliver at scale to industries such as e-fuels, steel, and grid applications.
“Our technologies are complementary, and together we can develop a better product that can be delivered at industrial scale to our customers, with VDL Groep as the manufacturing partner,” said Mattijs Slee, CEO of Battolyser Systems.
Willem van der Leegte, President and CEO of VDL Groep, added: “The combination of competences will result in a much stronger position to develop a state-of-the-art, ‘made in Europe’ electrolyser that will enable customers to produce competitive green hydrogen at large scale. This is essential for the successful transition to a sustainable energy supply.”
The merger is subject to approval by the European Investment Bank and is expected to take effect in Q4 2025. The shareholders of Battolyser Systems and VDL Hydrogen Systems will fund the merger equally and intend to continue supporting the company’s growth.
