Hydrogen Island project

Copenhagen Infrastructure Partners (CIP) has come up with the idea of BrintØ, which is an artificial island that will be used to make a lot of green hydrogen from offshore wind energy. The project is called “Hydrogen Island” (BrintØ in Danish) and will be located at Dogger Bank in the Danish part of the North Sea. The project is supposed to start making hydrogen by the end of 2030.

Hydrogen Island Project Overview

  • Location

Dogger Bank, Danish North Sea. This area has shallow waters and strong, consistent winds, making it an ideal site for harnessing wind power.

  • Capacity

The island will likely be linked to 10 GW of offshore wind power, which will be able to make about 1 million tons of green hydrogen every year. This amount is equal to about 7% of all the hydrogen that the EU is expected to use in 2030.

  • Purpose

BrintØ aims to supply a lot of green hydrogen to Europe so that it can help the energy transition to more environmentally friendly fuels. The hydrogen that is made could be used in cars, trucks, ships, and planes, which encourages the use of green fuels that are good for the environment.

  • Export Potential

Plans call for about 275 km of hydrogen pipelines to bring the green hydrogen to nearby countries like Germany, Belgium, and the Netherlands. This shows that the project could lead to international cooperation on energy issues.

Objectives and Goals

The BrintØ – Hydrogen Island project aims to build a big green hydrogen factory on a man-made island in the North Sea of Denmark. The main idea behind this project is to use offshore wind power to make hydrogen. It has big goals and objectives that fit with bigger environmental, economic, and strategic plans.


  1. Large-Scale Green Hydrogen Production

Utilize the 10 GW of offshore wind power connected to the island to produce approximately 1 million tons of green hydrogen annually.

  1. Power-to-X Technology Utilization

Employ Power-to-X technology to convert electricity from offshore wind into green hydrogen, thereby creating a sustainable fuel source for various modes of transportation, including cars, trucks, ships, and aircraft.

  1. Showcase Danish Expertise

Demonstrate Denmark’s capabilities in offshore wind, power-to-energy conversion, and green energy systems. The project aims to serve as a model for Danish innovation in these areas.


  1. Support the Green Transition:

The project is meant to be a key part of the global switch to green energy by creating a long-term alternative to making hydrogen from fossil fuels.

  1. Foster Economic Growth and Job Creation

The Brintø project wants to make Denmark a leader in making green hydrogen. This will help the country’s exports, lead to major economic growth, and create jobs.

  1. Strategic Energy Infrastructure Development

Make the Danish part of Dogger Bank the hub for building out offshore energy infrastructure in the North Sea in the future. Building energy islands, power cables, and hydrogen pipelines across the North Sea’s borders are all part of this.

  1. International Collaboration and Export

Through about 275 km of offshore hydrogen pipelines, the project plans to send green hydrogen to nearby countries like Germany, the Netherlands, and Belgium. This will encourage countries to work together on energy issues.

  1. Contribute to Danish and European Energy Goals

The project aims to be a significant step towards achieving these goals by providing a sustainable and inexhaustible energy source from the North Sea.

Production methods and technologies utilized

The BrintØ – Hydrogen Island project utilizes a combination of advanced technologies and methods to achieve its goal of large-scale green hydrogen production. The core of these technologies revolves around the integration of offshore wind energy with Power-to-X technology such as water electrolysis to produce green hydrogen.

Offshore Wind Energy

The project is planned to be connected to 10 gigawatts (GW) of offshore wind power. The Danish part of Dogger Bank provides this large amount of power. This area is famous for its shallow water and strong winds, which make it one of the best places in the world to make cheap green electricity. The location was chosen with care, taking advantage of the natural features to get the most out of the offshore wind farms in terms of output and efficiency.

Power-to-X Technology

Power-to-X (PtX) is a key technology utilized in the BrintØ project that turns electricity from offshore wind farms into green hydrogen. Electrical energy is used to electrolyze water, which breaks it down into hydrogen and oxygen. We researched many startups that focus on green hydrogen production technologies. You may become a member and check out how these startups produce green hydrogen.

The island should be able to make about 1 million tons of green hydrogen a year when it is running at full capacity (10GW). The green hydrogen that is made can then be used as a long-lasting fuel for trucks, ships, planes, and other vehicles, as well as for industrial processes that need hydrogen.

Hydrogen Pipeline for Export

A big part of the project is building the infrastructure to send the green hydrogen that is made to northwest Europe, to places like Germany, the Netherlands, and Belgium. Offshore hydrogen pipelines that are almost 275 km long will make this possible. This will make sure that the green hydrogen can be quickly sent across borders to places where it is needed most.

Key stakeholders

The key stakeholders involved in the BrintØ – Hydrogen Island project are primarily Copenhagen Infrastructure Partners (CIP) and COWI, along with Arkitema. These entities are collaborating to bring the ambitious vision of the BrintØ project to life.

Copenhagen Infrastructure Partners (CIP)

The BrintØ project is mainly supported and thought up by CIP. CIP is a top infrastructure fund manager that focuses on investing in renewable energy. To build this innovative hydrogen island, they are using their knowledge of greenfield renewable energy projects.


COWI is one of the best engineering, economics, and environmental science consulting firms in the world. They are working together with CIP on the BrintØ project and will use their knowledge of offshore renewable energy to help make the hydrogen island idea a reality.


Arkitema, an architecture firm, is also named as a partner in the BrintØ project’s growth. Along with COWI, they are helping CIP make the new idea of the hydrogen island a reality.

Timeline and milestones

The BrintØ project is expected to be in production by 2030.

By this time, the project is expected to have 10 GW of offshore wind power connected to it, which will primarily be used to produce green hydrogen via Power-to-X technology. The island is projected to produce around 1 million tonnes of green hydrogen per year when fully built out.

Current Situation

The project is in the proposal and planning stages.

Copenhagen Infrastructure Partners (CIP) has proposed the construction of this artificial island dedicated to the large-scale production of green hydrogen from offshore wind energy.
