The 23 partners behind Project Greensand have successfully submitted the final report for the pilot phase, which aimed to develop, test, and demonstrate the safe and efficient storage of CO2 in the North Sea subsurface. Supported by EUDP, this phase has produced concrete results, verifying the safety and feasibility of storing CO2 in the Nini West reservoir, located 1,800 meters beneath the seabed.
One of the key milestones of the project was the technical verification conducted by DNV, an independent and world-leading provider of risk, verification, and standardization services. Their analysis confirms that the stored CO2 remains securely in place and behaves as expected in the reservoir. This strong foundation provides Denmark with confidence to take the next steps toward large-scale carbon capture and storage (CCS). As Mads Gade, Country Manager at INEOS Denmark and Commercial Director at INEOS Energy, emphasized, this successful storage of CO2 in the North Sea subsoil will allow for significant reductions in atmospheric CO2 emissions and contribute to climate change mitigation.
The success of Project Greensand marks a global first in terms of developing a fully operational value chain for CO2 capture, transportation across borders, and offshore storage. This achievement was celebrated during the First Carbon Storage event on March 8, 2023, in Esbjerg, where His Majesty King Frederik signaled the initiation of CO2 storage in the North Sea. European Commission President Ursula von der Leyen and Denmark’s Minister for Climate, Energy, and Utilities Lars Aagaard also highlighted the project's significance in video and live speeches. Gade expressed pride in this accomplishment, noting that it brings Denmark and the EU closer to meeting their climate goals, thanks to the outstanding collaboration of the 23 consortium partners.
This project not only paves the way for CCS in Denmark but also provides valuable experience for Danish and international companies involved in CO2 capture, transport, and storage. These companies are now better equipped to play pivotal roles in the growing European CCS market. The intensive work during this pilot phase has enhanced their capacity to contribute to the global effort in mitigating climate change.
Building on the success of the pilot phase, INEOS, as the lead partner in Project Greensand, has already applied for approval for Denmark’s first large-scale CO2 storage facility in collaboration with partners Wintershall Dea (now Harbour Energy) and Nordsøfonden. The goal is to begin CO2 storage in the North Sea by late 2025 or early 2026, with an ambition to store up to 400,000 tonnes of CO2 annually. By 2030, this could increase to a total of 8 million tonnes stored under the North Sea seabed.
Meanwhile, efforts are also underway to explore the feasibility of onshore CO2 storage in Denmark. INEOS and its partners were awarded an exploration license earlier this year to assess the potential for CO2 storage in the Gassum reservoir, located in Jutland. The experience gained from Project Greensand will be invaluable as they aim to demonstrate safe storage practices both offshore and on land.
