About Us

Accelerating the energy transition

Green Hydrogen Hub Denmark aims to be the first fully commercially viable, 100% green, large-scale hydrogen production, storage and CAES solution.

GHH aims to expand across Europe and the rest of the world, staying fully aligned with Europe’s Green Deal ambitions to develop hydrogen and energy storage networks to enable the integration of renewables, the development of sectoral integration and the circular economy.

This will be a European flagship green energy project, accelerating the energy transition, promoting the deployment of hydrogen technologies globally, and establishing Europe as a leader in the cross-sectoral integration of renewable energy.

Electrolysis hydrogen production and long-duration underground storage

Green Hydrogen Hub Denmark is in Northern Jutland, Denmark, where large caverns suitable for storage of hydrogen are created in salt deposits.

Our location is close to existing energy infrastructure, including the high-voltage electricity transmission grid, the gas transmission network and underground gas storage and wind resourced in the Northern Seas Region.

Our electrolysis capacity targets are:

Year 2025 – 350MW
Year 2030 – 1,000MW

Our hydrogen capacity targets are:

Year 2025 – 200GWh
Year 2030 – 400GWh

Our hydrogen CAES targets are:

Year 2025 – 320MW
Year 2030 – 320MW


Corre Energy develops mass-energy storage facilities which are composed of assets (storage technologies), designed to provide various wholesale and retail storage solutions and services to the energy market.

Eurowind Energy A/S (EWE) is a Danish company, which has evolved into being a leading developer and operator of PV and wind turbine projects. They are involved in PV and wind turbine investments across Europe.

Gas Storage Denmark A/S owns and operates Denmark’s two underground gas storage facilities – the aquifer pore storage facility at Stenlille in the central part of Zealand and the salt cavern facility at Lille Torup in northern Jutland.

Strategic Partners

Hydrogen Valley is a competence center with more than 15 years of experience in establishing concrete Power-to-X projects. They develop concept designs, establish partnerships, encure financing and coordinate projects with Danish and European partners.

Everfuel is producing green hydrogen for zero-emission mobility, designed to be commercially available across Europe. They offer competitive all-inclusive hydrogen supply and fueling solutions.

Project of Common Interest

PCI status project

Projects of common interest (PCIs) are key infrastructure projects that are intended to help the EU achieve its energy policy and climate objectives: affordable, secure and sustainable energy for all citizens, and the long-term decarbonisation of the economy in accordance with the Paris Agreement. The goal is to help countries within the EU to achieve their energy policies and climate objectives.

The Green Hydrogen Hub preserves green energy for times when it otherwise would not be available.

EU Regulation No. 347/2013 (the “TEN-E Regulation”) provides for electricity PCIs to include interconnectors, transmission lines that provide cross-border benefit and large-scale electricity storage projects such as the CAES component of Green Hydrogen Hub Denmark.

The CAES component of Green Hydrogen Hub Denmark is included as project 1.21 on the 5th list of PCIs within the North Seas Offshore Group priority corridor.
