H2opZee

Demonstration project at sea for
green hydrogen in the Netherlands

The project at a glance

H2opZee is a hydrogen project in the Dutch part of the North Sea. The idea is to build electrolysers with a capacity of 300 to 500 megawatts far out at sea to produce hydrogen.

RWE will generate the power for the electrolysers with offshore wind, which will allow the production green hydrogen at sea. The aim of the project is to encourage the development of a hydrogen economy in the Netherlands.

Origin and partners of the project

H2opZee stems from an initiative of TKI Wind op Zee – a programme that encourages the development of wind innovations at sea.

RWE joined forces with Neptune Energy to develop this hydrogen project at sea.

Neptune Energy is the biggest offshore gas producer in the Dutch part of the North Sea.

RWE's part in the project

With H2opZee RWE becomes part of one of the world’s first and largest hydrogen projects of this type. The company contributes with its vast experience with offshore wind as well as its hydrogen expertise to the project.

With the lessons learned from this demonstration project, RWE’s aim is to contribute to the further development of the hydrogen economy in the Netherlands.

What will be the result of H2opZee?

The knowledge the Group is gaining with this project is strengthening the Dutch industry’s competitive position. This project promotes the offshore energy transition in the Netherlands. It helps to attract the production value chain of wind energy and green hydrogen to the Netherlands, as well as deliver technology and knowledge that we are able to export globally.

Project schedule

It is expected that the feasibility study will be completed by the end of 2023. At the end of 2030, RWE aims to start a demonstration site for 500 MW of green H2 offshore, in accordance with the ministry’s objectives.
