Intercepted CO2 injected into CCS World First under the North Sea Ship’s crew

A consortium led by British chemical company INEOS is claiming the world’s first injection of captured carbon dioxide into a depleted oil field in the Danish North Sea.

Dubbed Project Greensand, the initiative aims to demonstrate the feasibility of carbon capture and storage (CCS) to reduce carbon emissions in the fight against climate change.

The carbon dioxide was captured at an INEOS site in Belgium, converted into liquid form and successfully transported to the Danish North Sea, where it was permanently stored in the INEOS-operated Nini field at a depth of around 1,800 meters below the sea floor. His Royal Highness Crown Prince Frederik of Denmark initiated the injection at a ceremony on Wednesday.

“This is a breakthrough for carbon capture and storage. It is the first time carbon has been successfully captured, transported across borders and safely stored offshore anywhere in the world,” said Sir Jim Ratcliffe, supporter of Project Greensand and Founder and Chairman of INEOS.

INEOS and its partner Wintershall Dea lead the Project Greensand consortium, which is made up of 23 organizations from business, academia, government and start-ups. The project aims to safely capture and permanently store up to 8 million tons of carbon dioxide every year in the Siri area operated by Ineos from 2030, which corresponds to approximately 40% of Denmark’s total emission reduction target.

The European Commission estimates that the EU will need to store up to 300 million tonnes of CO2 per year by 2050 to meet its climate targets.

“This is a big moment for Europe’s green transition and for our clean tech industry. The first full value chain for carbon capture and storage in Europe”, Ursula von der Leyen, President of the European Commission. “They show that it’s possible. That we can grow our industry through innovation and competition, while removing carbon emissions from the atmosphere through ingenuity and collaboration. This is what Europe’s competitive sustainability is all about.”

Project Greensand is supported by Danish through the Energy Technology Development and Demonstration Program (EUDP). CCS is considered a key technology to achieve Denmark’s net zero target for 2045.

“The Greensand project proves that carbon capture and storage is a viable way to permanently store CO2 emissions under the North Sea. It plays a crucial role in achieving net zero in Denmark, Europe and beyond,” added Hugo Dijkgraaf, Member of the Board and Chief Technology Officer at Wintershall Dea.

The injected CO2 is closely monitored, contributing to the understanding and growth of carbon storage technology.

The sandstone fields of the larger Siri Fairway, which holds the Nini Field in the Danish North Sea, are at an optimal depth of 1,500 to 2,200 metres. The area is considered to be extremely stable geologically and a very safe permanent CO2 storage site, having stored gas and oil for more than 10 million years.
