This pivotal decision follows crucial support from the Dutch government through the OWE^[1] subsidy scheme, complementing prior support from the European Innovation Fund and the Dutch IPCEI^[2] program. Both this continued support as well as the refined regulatory framework were key to the project’s advancement.

As announced in February 2025, Air Liquide will invest more than 500 million euros to build, own and operate the electrolyzer, supplying notably TotalEnergies’ industrial platform through a long term contract. The ELYgator project will produce 23,000 tons of renewable hydrogen annually, serving industrial and heavy-duty mobility customers, reducing up to 300,000 tons of CO₂ emissions per year of operation.

This electrolyzer is a first of its kind integrating both Proton Exchange Membrane and Alkaline technologies on the same site. The project aims to be operational by the end of 2027.
