Denmark's King Frederik X Opens EU's First Full-Scale CO₂ Storage Site at Port of Esbjerg, Denmark

On 18 September 2026, His Majesty King Frederik X of Denmark officially opened the first full-scale carbon dioxide storage facility in the European Union, marking what project leaders and senior officials described as a decisive shift from experimental carbon capture to commercial operation. The ceremony took place at the Port of Esbjerg, where the Greensand CO₂ storage project, led by INEOS Energy, formally entered the market.

The Greensand Project and Its Partners

The Greensand facility forms part of a full carbon capture and storage value chain, capturing CO₂, transporting it by ship, and permanently storing it deep beneath the seabed in the Danish North Sea. The project is led by INEOS Energy and developed in partnership with Harbour Energy and the Danish North Sea Fund, known as Nordsøfonden. In its first commercial phase, Greensand expects to store up to 400,000 tonnes of CO₂ annually.

The project is designed to scale significantly, with an expected capacity of between four and eight million tonnes annually at full build-out. In this initial phase, the CO₂ entering the Greensand value chain comes primarily from Danish biomethane producers. Mads Gade, CEO of INEOS Energy Europe, indicated that the facility is positioned to expand well beyond that starting point.

"Greensand starts with biogenic CO₂, but its significance reaches far beyond that first step," Gade said. "We are ready to expand capacity to receive CO₂ from industries across Europe. Greensand is open for business, and a new European market for permanent CO₂ storage can now begin to take shape."

A High-Profile Opening Ceremony

The opening drew a prominent gathering of political and industry figures from across the European Union. Among those attending were Sir Jim Ratcliffe, Chairman of INEOS; European Commissioner for Energy and Housing Dan Jørgensen; Danish Minister of Finance Peter Hummelgaard; and Paloma Aba Garrote, Director of CINEA, the European Climate, Infrastructure and Environment Executive Agency.

Sir Jim Ratcliffe used the occasion to frame the project as evidence that industrial competitiveness and emissions reduction are not mutually exclusive goals. "Europe will not achieve net zero by closing factories and exporting jobs," Ratcliffe said.

"Government needs to work hand in hand with industry to allow industry to remain competitive while reducing emissions. Greensand proves this can be done. So, Greensand works. The storage is ready. We are open for business."

EU and Danish Officials Respond

European Commissioner Dan Jørgensen described the launch as proof that carbon storage has moved beyond theory and into practical deployment. "Today marks an important milestone for Europe," Jørgensen said at the ceremony in Esbjerg.

"With the launch of the first fully operational site for offshore carbon storage in the European Union, we prove that carbon storage is a practical reality. We show that we can move from demonstration to deployment. We set out a path for European industries: to continue their transition to a low-carbon future while maintaining production, investments, and employment in our continent. And we open a new front in the existential fight against climate change."

Danish Finance Minister Peter Hummelgaard positioned Denmark as taking a leading role on behalf of the wider European bloc. "Project Greensand is a concrete example of how green technology can strengthen both Europe's climate action and our resilience," Hummelgaard said.

"Today, we are taking a major step forward, and Denmark is leading the way on behalf of Europe. Today, we are not merely opening a facility; we are opening a new chapter for our shared climate ambitions." Paloma Aba Garrote, Director of CINEA, emphasized the broader significance of public and private collaboration in making the project possible.

"Today's celebration is therefore more than a technical achievement," Garrote said. "It represents a tangible step towards climate neutrality, a demonstration of the EU's capacity to reduce CO₂ emissions while safeguarding competitiveness and jobs across Europe. It shows that when industrial ambition is matched with strong public support and a collaborative spirit, real impact becomes possible."

What the Opening Means for European Industry

With Greensand now in commercial operation, industrial emitters across the European Union have, for the first time, access to infrastructure capable of transporting and permanently storing CO₂ at scale. The facility is described by its developers as offering a practical route to reducing emissions without requiring the shutdown of the industries that underpin European economic activity. The opening at Esbjerg was presented not only as a milestone for the Greensand project itself but also as the beginning of a broader market.

The question raised by the project's own communications is how quickly the EU will establish the regulatory frameworks, infrastructure networks, and investment conditions needed for industrial emitters to capture CO₂ at the scale the facility is designed to accommodate.

INEOS Energy's Mads Gade signalled that the commercial infrastructure is now in place and that the next phase depends on the appetite of European industries to connect to it. With storage capacity ready and the first CO₂ already entering the value chain from biomethane producers, the project is structured to receive volumes from a far wider range of industrial sources as demand and regulatory conditions develop.
