Key Takeaways
- INEOS’s Greensand project will become EU’s first operational offshore CO2 storage site in 2025
- Initial capacity of 400,000 tons annually, scaling to 8 million tons by 2030
- Technology stores CO2 1,800 meters beneath North Sea in depleted oil reservoirs
- Environmental groups warn against using CCS to delay emission reductions
The Nini oil field in the North Sea is undergoing a dramatic transformation from fossil fuel extraction site to Europe’s pioneering carbon storage facility. Chemical giant INEOS is preparing to launch the Greensand project, which will inject liquefied carbon dioxide deep beneath the seabed in a process that essentially reverses oil extraction.
Europe’s First Offshore CO2 Storage
When commercial operations begin next year, Greensand will become the European Union’s first fully-operational offshore CO2 storage site. The project represents a significant step in carbon capture and storage (CCS) technology deployment across Europe.
Mads Gade, chief executive of INEOS Energy Europe, outlined the ambitious scaling plans: “We will initially begin storing 400,000 tons of CO2 per year, scaling up to as much as 8 million tons annually by 2030.”
“Denmark has the potential to actually store more than several hundred years of our own emissions,” says Gade. “We are able to create an industry where we can support Europe in actually storing a lot of the CO2 here.”
Infrastructure Development
The project involves significant infrastructure development across Northern Europe:
- A CO2 terminal under construction at Port of Esbjerg for temporary storage
- Purpose-built carrier vessel “Carbon Destroyer 1” being built in the Netherlands
- Partnerships with Danish biogas facilities to bury captured emissions
Scientific Backing and Geological Suitability
Experts confirm the Greensand sandstone formation is ideally suited for carbon storage. Niels Schovsbo, senior researcher at the Geological Survey of Denmark and Greenland, explained: “Almost a third of the rock volume is made up of tiny cavities.”
“We found that there are no reactions between the reservoir and the injected CO2. And we find that the seal rock on top has sufficient capacity to withhold the pressure,” added Schovsbo.
Controversy and Scale Challenges
Despite the technological promise, carbon capture faces significant challenges and criticism. The technology currently captures only a tiny fraction of global emissions and sometimes uses fossil fuel energy in operations.
Helene Hagel, head of climate policy at Greenpeace Denmark, expressed concerns: “We could have CCS on those very few sectors where emissions are truly difficult or impossible to abate. But when all sectors say we need to just catch emissions instead of reducing them — that is the problem.”
The scale challenge is substantial: while Greensand aims to store 8 million tons annually by 2030, global CO2 emissions reached nearly 38 billion tons last year.
EU Policy Context
The European Union has proposed developing at least 250 million tons of CO2 storage capacity annually by 2040 as part of net-zero emissions targets for 2050. The Intergovernmental Panel on Climate Change recognizes CCS as a valid tool in climate mitigation.
Gade defended the dual approach of carbon storage alongside continued fossil fuel development: “We don’t want to deindustrialize Europe. We want to have actually a few instruments to decarbonize instead.”
The company plans to develop another previously unopened North Sea oil field while expanding carbon storage capabilities, arguing that domestic production has a lower environmental footprint than imports.
