- Air Liquide invests over 500 million euros in a 200 MW electrolyzer in Maasvlakte.
- The project will produce 23,000 tons of renewable hydrogen annually.
- It aims to reduce up to 300,000 tons of CO₂ emissions per year.
- Operational start is planned for the end of 2027.

Project Overview
Air Liquide has decided to construct a 200 MW electrolyzer, named ELYgator, in Maasvlakte, Port of Rotterdam. This project is a significant step in European decarbonization efforts, focusing on low-carbon hydrogen production.
Financial and Government Support
The project benefits from substantial financial backing, with Air Liquide investing over 500 million euros. It has received crucial support from the Dutch government through the OWE subsidy scheme, as well as from the European Innovation Fund and the Dutch IPCEI program.
Production and Environmental Impact
ELYgator will produce 23,000 tons of renewable hydrogen annually, primarily serving industrial and heavy-duty mobility sectors. The project is expected to reduce up to 300,000 tons of CO₂ emissions per year.
Technological Innovation and Timeline
This electrolyzer is unique, integrating both Proton Exchange Membrane and Alkaline technologies on the same site. The project aims to be operational by the end of 2027.
