Alquion

What Alquion does

Alquion B.V. is a Dutch cleantech company that develops and commercializes the Flexolyser™, a fully flexible pressurized alkaline electrolyser for industrial-scale green hydrogen production. The company was formed in February 2026 through the merger of Battolyser Systems and VDL Hydrogen Systems, combining electrochemical cell R&D (Battolyser) with stack industrialization and manufacturing scale (VDL Hydrogen Systems / VDL Groep). Alquion is headquartered across Schiedam and Eindhoven in the Netherlands, with a 50 kW pilot installed at the Technical University of Eindhoven, and operates with approximately 50 employees.

The Flexolyser™ is positioned as the first fully flexible alkaline electrolyser with unlimited start/stop capability and no performance degradation, in contrast to conventional systems that require 20-40% minimum load. The product integrates internal electricity storage, a pressurized architecture that reduces OPEX and downstream compression costs, and RFNBO-compliance for green hydrogen certification. By converting low-cost electricity to hydrogen when power prices are low and selling electricity back to the grid when prices are high, the Flexolyser targets up to 25% lower levelized cost of hydrogen versus alternative electrolyser technologies. The roadmap moves from the existing 50 kW pilot to a 0.5 MW demonstration at an industrial customer site in May 2026, followed by a 5-10 MW first-of-a-kind production system.

Alquion generates revenue through one-time sales of Flexolyser systems to industrial customers in chemicals, e-fuels, steel, and grid/network applications, with VDL Groep as the stack manufacturing partner. The go-to-market is enterprise field sales, supported by an ecosystem of strategic partners (HyCC, Eneco, RWE, Port of Rotterdam, NXTgen) and academic collaborators (TU/e, TUDelft, University of Twente). Main shareholders include VDL Groep, Innovation Industries, Global Cleantech Capital, Invest-NL, and Koolen Industries, and the company is a member of the HyValueChain consortium developing a Dutch electrolyser supply chain.

Core offering

Alquion develops and markets the Flexolyser™, a fully flexible pressurized alkaline electrolyser designed for large-scale industrial green hydrogen production. The system can be switched on and off safely and repeatedly without performance degradation, allowing operators to directly follow volatile renewable electricity prices and convert low-cost power into hydrogen. Stack manufacturing is handled by VDL Groep, with a 0.5 MW demonstration unit planned at an industrial customer site in May 2026 followed by a 5-10 MW first-of-a-kind production system.

Product overview

Alquion offers a single unified product: the Flexolyser™, the first fully flexible pressurized alkaline electrolyser for industrial applications. This electrolyser integrates renewable energy sources (such as offshore wind) into the energy system by converting excess electricity into hydrogen when power prices are low, and can shut off without performance loss when wind conditions are low. The Flexolyser enables up to 25% lower LCOH compared to alternative electrolyser technologies through unlimited start/stop capability and direct load following of renewable energy sources.
