Air Liquide has taken the final investment decision for its ELYgator project: a 200 MW electrolyser to be built at Maasvlakte, in the Port of Rotterdam. The project is backed by the European Union and the Dutch government.
The company will invest more than €500 million to construct and operate the plant, which will supply renewable hydrogen to TotalEnergies’ industrial platform under a long-term contract. Once operational, ELYgator will produce 23,000 tonnes of renewable hydrogen annually for industry and heavy-duty mobility, cutting CO₂ emissions by around 300,000 tonnes each year.
“This investment decision is a major step forward and demonstrates our commitment to developing renewable hydrogen. We are convinced that robust, large-scale projects such as ELYgator will have a real impact on industry and heavy-duty mobility in Europe,” said Emilie Mouren-Renouard, member of Air Liquide’s Group Executive Committee with responsibility for European activities.
A new milestone with TotalEnergies
ELYgator will also be the first electrolyser to combine proton exchange membrane and alkaline technologies on the same site. It is scheduled to be operational by the end of 2027.
In addition, Air Liquide and TotalEnergies are planning a joint venture to build a 250 MW electrolyser in the province of Zeeland, also in the Netherlands. Powered by renewable electricity from TotalEnergies’ OranjeWind offshore wind project, it is expected to produce up to 30,000 tonnes of renewable, low-carbon hydrogen per year. Subject to final approvals and the investment decision, completion is targeted for 2029.
