The Greensand Future Project
The Greensand Future Project is a carbon capture & storage project in the Danish North Sea. The project will become the first full-scale CO2 storage facility in the EU.
INEOS Energy is leading the project, and we are supporting in collaboration with Harbour Energy and Nordsøfonden by delivering multidisciplinary engineering across key project assets.
By repurposing mature fields, we showcase how the oil & gas sector can play a critical role in decarbonizing.
Carbon Capture and Storage
CO2 emitters, such as biogas plants, will capture CO2 and liquify it for truck transport. Trucks will then transport the CO2 to the transit storage and ship-loading facilities at Esbjerg Port in Denmark.
The CO2 carrier ship will transport the CO2 to the Nini A platform in the North Sea, 300 km West of Esbjerg, and inject it into a depleted oil reservoir.
The project is a major step in transforming depleted oil & gas reservoirs into secure CO2 storage sites.
400,000 tonnes of CO2
The project aims to safely capture and permanently store 400,000 tonnes of CO2 each year as a starting point. This will allow a gradual expansion of storage capacity towards 2030. The initial storage will be at the Nini A platform in the depleted Nini West reservoir in the North Sea.
Our scope of work includes
The project combines topside modification, marine systems engineering, process design, and offshore platform upgrades. ISC has carried out:
- Detailed design of the ship-based CO2 injection system
- Detailed design of modifications to the Nini A platform
- Engineering assistance for the Esbjerg Port CO2 terminal.
Our floating injection solution demonstrates how existing offshore oil & gas expertise can be leveraged to accelerate scalable CCS deployment.
Our vessel design integrates CO2 storage tanks, injection module, and integrated systems, including:
- Control room
- Boiler system
- High-pressure pumps
- On-/offloading systems
