Alquion has taken the final investment decision for a 500 kW demonstration electrolyser at the site of the Nyrstar zinc smelter in Budel (NL). The Flexolyser is set to demonstrate, as a flexible electrolyser, that it can be switched on and off more than twenty times a day without suffering any degradation. This has been reported by Alquion. The construction and operation of the project will cost a total of 10 million euros. The consortium partners will receive a grant of 3.7

Battolyser Systems and VDL Hydrogen Systems have merged, continuing their activities under the name Alquion and outsourcing assembly to VDL Groep. Alquion develops the Flexolyser®, a fully flexible and high-capacity alkaline electrolyser designed to integrate large-scale renewable energy sources into the energy system. The merger was announced in July 2025 and has now been formalized. Alquion will continue as an independent cleantech scale-up to bring the Flexolyser to market

Battolyser Systems and VDL Hydrogen Systems have agreed to merge their activities into a single company to bring the first fully flexible electrolyser for large-scale industrial applications to market. The merged company will develop and market the electrolyser with VDL Groep as stack manufacturing partner. Pilot projects are ongoing with industrial customers, followed by full scale demonstrations and commercial ramp-up thereafter. The cost of green hydrogen remains too high
