Project Greensand has opened the EU's first full-scale commercial offshore CO2 storage site, injecting CO2 from Danish biomethane plants into the depleted Nini West field. Initial capacity is 400,000 tonnes per year with plans to reach 4-8 million tonnes as demand grows. The project uses a dedicated CO2 carrier and truck transport from capture points to the Port of Esbjerg. Meanwhile, Heerema started fabrication of the jacket for TenneT's second 2-GW offshore converter platform, part of a standardized design for IJmuiden Ver Beta and Gamma and Nederwiek 2. The standardization aims to cut costs and accelerate North Sea wind grid connections. Aker BP also reported a modest gas discovery near Duva, and Viridien won a five-year contract for digital monitoring of decommissioned Stella assets.

The 2-GW converter jacket standardization is the real story here. TenneT reusing designs across IJmuiden Ver and Nederwiek should cut fabrication cost and schedule risk. Curious if the 525 kV DC link is also standardized or if that varies per project. That's where the real learning curve shows.

Greensand opening is notable but the 400k mt/yr capacity is tiny against European emissions. The expansion to 4-8 million mt/yr depends on demand signals. If EU ETS carbon prices stay where they are, storage operators need clarity on cross-border CO2 transport rules. That will decide whether this scales.

Good roundup. The gas discovery is small but proximity to Duva helps. The CCS launch is the bigger deal, first commercial offshore storage in EU. Also nice to see decommissioning monitoring moving to satellite and AIS instead of guard vessels, that cuts cost and emissions.

The Viridien contract for Stella is interesting because it shows post-decommissioning oversight is becoming a data service, not a boat-on-station job. Five year contract for AIS and satellite monitoring. That is a pattern we will see more of as older platforms get removed.
