UK chemicals company INEOS has chosen US group ITT’s Svanehøj unit, based in Denmark, to supply carbon dioxide (CO2) pumps for Project Greensand, a carbon storage project in the Danish North Sea. Under the deal, Svanehøj will provide pumps for both the project’s onshore facility at Port Esbjerg and its first dedicated liquid CO2 (LCO2) carrier, developed with Royal Wagenborg.
After a successful trial, the storage operations of Project Greensand are set to begin in late 2025 or early 2026. In its first phase, the project aims to store 400,000 tonnes of CO2 per year, with plans to scale up to eight million tonnes annually as CO2 capture grows.
“We have worked closely with INEOS’ development team over the past year to specify customised pump solutions for both the onshore terminal and the vessel,” said Magnus Madsen, Sales Manager, Cargo Gas at Svanehøj. “It has been a rewarding process, allowing us to leverage our expertise in CO2 and contribute to an optimised design.”
Svanehøj has experience supplying CO2 pumping systems for marine applications, having delivered its first cargo pump for an LCO2 carrier in the 1990s. More recently, the company has provided CO2 pumps for the Northern Lights project in Norway and LCO2 carriers under construction at HD Hyundai Mipo.
The latest agreement with INEOS is part of the company’s continued focus on carbon capture and storage (CCS) technology, as demand for infrastructure supporting CO2 transport and storage grows.
Project Greensand’s storage plans
Project Greensand is named after the sandstone formations beneath the Danish North Sea where the CO2 will be stored. The project will create a full CO2 storage chain, with captured and liquefied CO2 from Danish biogas producers transported offshore and injected into depleted oil wells in the Nini Field.
To support these operations, INEOS has partnered with Royal Wagenborg and Royal Niestern Sander shipyard to develop the first purpose-built LCO2 carrier for the project. Based on the EasyMax vessel design, the carrier will be built with high load capacity and low fuel consumption and is expected to enter service by the end of this year.
With its first large-scale phase underway, Project Greensand is part of Denmark’s wider push to develop carbon storage by using existing offshore infrastructure.
Denmark has set ambitious climate goals, aiming to cut greenhouse gas emissions by 70% by 2030 compared with 1990 levels and to achieve Net Zero by 2045. To support this, the country is investing in carbon capture, utilisation, and storage (CCUS) alongside its expanding renewable energy sector, particularly offshore wind. The Danish government has also introduced funding programmes and regulations to support CO2 transport and storage, positioning Denmark as a potential hub for CO2 management in Northern Europe.
