• The completion of Europe’s first offshore CO₂ carrier marks a pivotal milestone in the energy transition and the advancement of carbon capture and storage (CCS) infrastructure within Europe.
• All ship sections of the vessel have now been successfully constructed and assembled at Royal Niestern Sander shipyard in the north of the Netherlands.

Mads Gade, CEO of INEOS Energy Europe, says:
“The completion of all sections of the CO2 vessel is a giant step forward for transportation of CO2 in the EU. This ship is essential to our ambition of establishing the first full-scale CO₂ storage facility in the EU. With the carrier now entering its next construction phase, Greensand are getting closer to completing Europe’s first full CCS value chain.”

Edwin de Vries, Director of Wagenborg Offshore, says:
“We are proud to reach this important milestone together with INEOS for the Project Greensand. The vessel is the first of its kind made in the EU and shows how the maritime industry in the North of the Netherlands can contribute to the energy transition. Construction is progressing steadily and according to plan.”

The dedicated CO₂ carrier currently under construction at Royal Niestern Sander shipyard in the Netherlands is a cornerstone in Greensand’s mission to deliver EU’s first full-scale carbon capture and storage (CCS) value chain.

The construction of this unique vessel in the Netherlands underscores the innovative spirit of northern Dutch shipbuilding. Wagenborg and Royal Niestern Sander have previously pioneered game-changing vessels such as ‘walk-to-work’ offshore support ships and the EasyMax series.

The landmark agreement between INEOS and Wagenborg for the delivery of this new-build CO₂ carrier was signed in November 2024, in the presence of HM King Willem-Alexander of the Netherlands and HM King Frederik of Denmark.

The vessel is specifically designed to transport liquefied CO₂ from onshore capture sites to offshore storage in the Danish part of the North Sea. Once launched and operational, the carrier will sail regular routes from Port Esbjerg to the Nini West platform, where the CO₂ will be injected for safe and permanent storage to the Nini reservoir approx. 1,800 metres beneath the seabed.

These geological formations have securely contained hydrocarbons for millions of years and have been thoroughly assessed and certified for safe and permanent CO₂ storage.

Mads Gade, CEO INEOS Energy Europe says: 
”The geology in the Danish part of the North Sea is very well suited for safe and permanent storage of CO2. By fulfilling the potential for storage of CO2 deep below the subsurface in the Danish North Sea we can make a significant contribution to achieving both Danish and European climate goals. The CO2 carrier will play a pivotal role for Greensand in establishing and developing the first operational CO₂ storage facility in the EU aimed at mitigating climate change”.

The ship itself is designed to meet the highest standards for safety and environmental performance and is tailored to the specific technical requirements of CO₂ transport, including onboard cooling and pressure systems. With the completion of the ship’s hull, the vessel enters the next phase of construction, which includes retrofitting, commissioning, testing, and sea trials.

This milestone follows a series of major developments in the Greensand project. In December 2024, INEOS and its partners Harbour Energy and Nordsøfonden made the Final Investment Decision (FID) to move ahead with full-scale CO₂ storage operations in the Nini Field.

With the plan to initiate safe sand permanent CO₂ storage in the Nini Field by late 2025/early 2026, Greensand is expected to become the EU’s first operational CO₂ storage facility aimed at mitigating climate change. This investment decision has paved the way for expected investments exceeding 1 billion DKK across the Greensand CCS value chain to scale up storage capacity.

The dedicated carrier is central to fulfilling this ambition, enabling safe, efficient, and scalable transport of captured CO₂ from across Europe to the Danish storage site.

Construction has progressed steadily with several key sections of the vessel completed and assembled. Earlier this year, the successful and safe transport of the aft ship marked another significant step forward.

Project Greensand aims to begin regular offshore CO₂ injection by the end of 2025 or early 2026. The project’s initial phase targets the permanent storage of 400,000 tonnes of CO₂ annually, with the potential to scale up to 8 million tonnes per year by 2030. The arrival of the new CO₂ carrier will be vital in ensuring this ambition becomes a reality – not only for Denmark but for Europe’s broader climate goals.
