Start-up of Greensand CCS, the EU’s first full-scale CO2 storage site
22/09/26
In another milestone for Harbour, the Ineos-operated Greensand carbon capture, storage and transport project in the Danish North Sea, in which Harbour holds a 40 per cent interest, has successfully achieved first injection of CO2. Greensand started commercial operations on 18 September 2026 and is the first full-scale CO2 storage site in operation in the EU and can store up to 400,000 tonnes of CO2 per year in the initial phase.
CO2 will be liquefied and shipped to the depleted Nini West oil field, roughly 250km off the coast of Denmark and 1800m below the seabed.
Graeme Davies, EVP Global CCS, said:
This is a significant achievement for the project and the teams involved. It demonstrates how existing offshore infrastructure can be repurposed to support carbon storage."
Harbour has a leading CO2 storage position in Europe. Greensand is a scalable, low-cost and commercial project, representing a key project in Harbour’s high graded CCS portfolio.
Notes to editors:
Greensand Future partners comprise INEOS E&P (40%, operator), Harbour Energy (40%) and Nordsøfonden (20%).
The CO2 stored by the project comes mainly from Danish biomethane emitters and is transported via trucks to the Port of Esbjerg before being shipped offshore for permanent storage aboard Carbon Destroyer 1, the EU's first purpose-built CO2 carrier.
CCS has a critical role to play in the energy transition and in enabling countries to meet their climate commitments; Harbour is working with governments to enable a supportive policy environment and an accelerated deployment of CCS at scale.
