Air Liquide takes the final investment decision to
build ELYgator, a large-scale electrolyzer in the
Netherlands
Air Liquide takes a major step forward in European decarbonization efforts with the final investment
decision to launch the construction of ELYgator, a 200 MW electrolyzer project in Maasvlakte, in the Port of
Rotterdam. This project reinforces our leadership in low-carbon hydrogen production and represents a
significant advancement in the decarbonization of European industrial needs.

This pivotal decision follows crucial support from the Dutch government through the OWE1 subsidy scheme,
complementing prior support from the European Innovation Fund and the Dutch IPCEI2 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.

Emilie Mouren-Renouard, Group Executive Committee member, notably in charge of supervising activities in
Europe, said: “This investment decision is an important milestone and demonstrates our commitment to
renewable hydrogen development. We firmly believe that robust, large-scale initiatives like ELYgator will
deliver a real impact for the European industry and heavy-duty mobility sectors. We welcome the support from
the Dutch Government, which has been instrumental in our decision to move forward with this significant
decarbonization project. ELYgator illustrates our drive to develop concrete technologies and solutions that
directly contribute to Europe’s ambitions towards climate neutrality by 2050.”
