Hydrogen Island


In 2022, CIP proposed to build an artificial island dedicated to large-scale production of green hydrogen from offshore wind – called “BrintØ” (Hydrogen Island) – in the Danish part of the North Sea. The island is expected to be able to supply an unprecedented amount of green hydrogen by 2030 and will thus be a crucial step in securing Europe’s future green energy supply.

BrintØ is envisaged to be established on the Danish part of Dogger Bank; an area expected to become a central hub for the future build-out of offshore energy infrastructure in the North Sea. The area consists of a 20,000 km2 sandbank and offers some of the world’s best conditions for producing low-cost green electricity, due to low water depths and strong wind resources.

The overall project will comprise four main elements: offshore wind, an artificial island, Power-to-X facilities and a hydrogen pipeline for export.

Offshore wind

The island is planned to be connected to 10 GW of offshore wind. The energy production will be enough to power approximately 10 million European households.

Artificial island

The island will be an artificial island and serve as a hub for connection of surrounding offshore wind farms. The island will house large-scale hydrogen production facilities, and an operations and maintenance (O&M) harbour for servicing offshore wind farms.


Large-scale hydrogen production facilities will be established on the island, which will be able to convert renewable energy into green hydrogen via Power-to-X. At full capacity (10GW), the island is expected to produce around 1 million tonnes of green hydrogen, corresponding to roughly 7% of Europe's expected hydrogen demand in 2030.

Hydrogen pipeline

A pipeline will be used to transport the green hydrogen to northwestern Europe (e.g., Germany, the Netherlands, Belgium), where significant demand is expected.
