Two Large-Scale Electrolyzers in the Netherlands to Produce Green Hydrogen for Industry and Mobility
In a major step toward decarbonizing European industry and transportation, Air Liquide has announced two large-scale hydrogen projects in the Netherlands, in collaboration with TotalEnergies. These initiatives will see the construction of two electrolyzers with a combined capacity of 450 MW, significantly reducing CO₂ emissions from industrial processes and heavy-duty transport.
With a total investment exceeding €1 billion, the projects are expected to eliminate up to 500,000 tonnes of CO₂ emissions annually, reinforcing Air Liquide’s position as a leader in clean hydrogen production.
Project 1: ELYgator – A 200MW Green Hydrogen Electrolyzer in Rotterdam
Air Liquide will build, own, and operate a 200MW electrolyzer at Maasvlakte, Rotterdam, with the capacity to produce up to 23,000 tonnes of green and low-carbon hydrogen per year.
This renewable hydrogen will primarily supply TotalEnergies’ industrial platform under a long-term agreement, while also supporting industrial and heavy-duty mobility customers in the Netherlands and Belgium via Air Liquide’s existing hydrogen pipeline network.
The ELYgator project will be powered by:
- Renewable electricity from TotalEnergies’ share of the OranjeWind offshore wind farm
- Power Purchase Agreements (PPAs) with Vattenfall’s Hollandse Kust Zuid (HKZ) offshore wind farm
The project has already secured EU Innovation Fund and Dutch IPCEI program support and is expected to be operational by the end of 2027, pending regulatory approvals and subsidies.
Project 2: 250MW Electrolyzer Joint Venture with TotalEnergies in Zeeland
Air Liquide and TotalEnergies are also forming a 50/50 joint venture to develop a 250MW electrolyzer in Zeeland, Netherlands.
This facility will produce up to 30,000 tonnes of green and low-carbon hydrogen annually to further support TotalEnergies’ refinery operations and other industrial users. It will be powered entirely by TotalEnergies’ renewable electricity from the OranjeWind wind farm.
Subject to final investment decisions and permitting, the Zeeland electrolyzer is expected to be operational by 2029.
Technological Innovation and Strategic Impact
Both electrolyzers will leverage Air Liquide’s advanced electrolysis technology, developed through its joint venture with Siemens Energy.
Emilie Mouren-Renouard, Executive Committee Member at Air Liquide, highlighted the significance of these projects:
“These flagship initiatives are critical for reducing emissions in hard-to-abate sectors like industry and heavy transport. We are proud to lead Europe’s renewable and low-carbon hydrogen production and to support TotalEnergies in decarbonizing its industrial operations. These projects complement our five existing low-carbon hydrogen units in Europe, reinforcing our commitment to achieving carbon neutrality by 2050.”
Vincent Stoquart, President of Refining & Chemicals at TotalEnergies, added:
“This partnership marks another key milestone in TotalEnergies’ goal to fully decarbonize hydrogen use at our European refineries by 2030. By utilizing renewable electricity from our offshore wind farms, we are advancing our integrated strategy to produce cleaner energy and reduce our carbon footprint.”
Supporting Europe’s Hydrogen Future
These projects align with EU climate policies and have received financial backing through:
- EU Innovation Fund, which supports breakthrough low-carbon technologies
- IPCEI Hydrogen, a Dutch subsidy program supporting large-scale hydrogen infrastructure
By scaling up renewable hydrogen production, Air Liquide and TotalEnergies are pioneering the clean energy transition, accelerating industrial decarbonization, and strengthening Europe’s energy independence.
