Green hydrogen contributes to a sustainable Amsterdam Metropolitan Area


Project in general

The hydrogen will be used for the decarbonization of indrustry and mobility in the Amsterdam Metropilitan Area. For example, hydrogen can be used for the production of green steel, for making sustainable aviation fuels (SAF), for inland shipping or for new forms of circular chemistry that emit less or no CO2.


The feasibility study for the project was completed in 2022, with the aim of taiking the final investment decision (FID) in 2023 so the first hydrogen can be delivered in 2025/2026.

The factory will only use renewable electricity, mostly coming from offshore wind. The plant will be directly connected to offshore wind via the high voltage network of the national grid operator TenneT, preventing congestion of regional networks.

Green hydrogen technology

Green hydrogen is made by splitting water into hydrogen and oxygen with renewable electricity. This technique is called electrolysis. No CO2 is produced or emitted in the process. A similar technology has been safely applied for over a century in the chemical industry to produce chlorine.

There are multiple types of electrolysers available to produce hydrogen, like PEM and alkaline electrolysers. The decision for a specific technology and supplier will be made in the design phase.

The hydrogen is available for industrial parties in the region that are looking to become more sustainable. HyCC produces the hydrogen and the Port of Amsterdam and GasUnie take care of the distribution of the hydrogen in the region. For more information you can get directly reach out to HyCC.

H2ermes has a production capacity of ca. 15.000 tons of green hydrogen per year. This is the energetic equivalent to 500 gigawatt our of natural gas. This results in a CO2 reduction of 120.000 tons per year.

Environmental & Social Impact

Yes. The factory is developed by HyCC. HyCC is a part of Nobian, a company with over 100 years of experience with electrolysis for the safe production of chlorine. The company operates under strict standards to ensure the safety. In the design of the factory safety will be a priority. In addition, an extensive risk analysis (a QRA or ‘quantitative risk assessment’), will be made to confirm the safety of the factory.

You will not be able to hear the factory from surrounding areas. Electrolysis is a quiet process. For cooling towers, compressors, and other equipment quiet technologies will be used. For example, engines with lower rpm.

During the electrolysis process no emissions are released, except for oxygen and incidentally hydrogen. The hydrogen and oxygen are not harmful for the environment when released into the atmosphere. The factory is free of incineration units as electricity is used for heating and back-up power.

There are several opportunities to provide feedback throughout the project. stakeholders can ask their questions, share feedback, or request a personal conversation via the contact form on our website. The feedback from residents and other stakeholders will be included in the further development of the project and the permit application. Prior to the first construction activities, we will also organize information events about the project for personal discussion.
