INEOS E&P AS let a contract to Aquaterra Energy to support life extension of the Nini platform for CO2 injection as part of the Project Greensand CCS development offshore Denmark.
Aquaterra will support repurposing the platform for service until 2045 by determining the viability of the structure and guiding implementation of any necessary modifications. Nini platform represents the initial project stage and will serve as the basis for the adaptations of further nearby platforms in later phases of the project.
Greensand aims to store up to 1.5 million tonnes/year (tpy) of CO2 in 2025-26, and as much as 8 million tpy by 2030, making it a key project in meeting the International Energy Agency’s sustainable development scenario goal of 5,635 megatons of CO2 stored globally per year by 2050.
Project Greensand’s pilot stage used Nini West field for CO2 storage. The storage area has been extended to Nini Main field to start commercial operations. CO2 is transported on ships, transferred to the Nini platform, then pumped into the sandstone reservoirs through injection wells. Expansion to 8 million tpy will use depleted fields in the Siri Fairway (OGJ Online, June 15, 2023).
Wintershall Dea Norge AS and INEOS received the first CO2 storage licenses for Project Greensand earlier this year from the Danish Ministry of Climate, Energy, and Utilities. The consortium behind Project Greenway consists of 23 companies and includes Noble Corp., Aker Carbon Capture ASA, and Blue Water Shipping Inc. in addition to Wintershall and INEOS.
