EU's Greensand CO2 storage site begins commercial operations off Denmark's coast

The EU's first full-scale CO2 storage site, Greensand, has entered commercial operation off the coast of Denmark. The facility, located in a depleted oil field 1,800m below the seabed, will initially inject over 100,000 tonnes of CO2 per year. In its first phase, it aims to store 400,000 tonnes of biogenic CO2 annually, captured from Danish biomethane production, with plans to scale to 4-8 million tonnes per year by 2030. The project is led by Ineos Energy with partners Harbour Energy and Nordsøfonden, and received support from EU ETS funding. CO2 is transported by truck and ship to the site, using a dedicated carrier vessel. The reservoir has been verified for safety and stability. This milestone demonstrates that carbon capture and storage can move from demonstration to deployment, providing a practical path for industrial decarbonization in Europe.

Finally a full-scale CO2 storage site in the EU. 100k tonnes a year is small compared to what's needed, but the scaling plan to 4-8mtpa by 2030 is the real story. Good to see EU ETS money backing infrastructure like this.

Question is how they monitor the reservoir long term. They say 94% avoidance, but that's after accounting for the 6% from operations. What's the actual injection pressure and leak detection protocol? Depleted oil fields aren't all the same.

The EU ETS funding is a key signal. If carbon storage can become a revenue stream, you'll see more projects like this. But the regulatory framework needs to catch up. The 250mtpa target by 2040 means we need dozens of these sites, not one.

Biogenic CO2 storage is interesting because it can be carbon negative. But 400k tonnes from biomethane is a niche. The real test is whether they can handle fossil CO2 at scale without the same accounting benefits.

For industrial emitters, this is a practical option. But the logistics of trucking CO2 to port and shipping it out adds cost. At what price per tonne does this become viable for a cement plant or steel mill? The article doesn't say.
