Harbour Energy has a leading CO2 storage position in Europe and the UK with net storage resources of over 650 million tonnes of CO2. It offers the potential for long-term and stable cash flows which are complementary to Harbour’s business and provide a diversity of revenue that is not linked to oil and gas prices.
In 2025 we continue to mature our operated Viking project in the UK towards a potential final investment decision (FID) alongside the Acorn project in Scotland, while the Wintershall Dea transaction strengthened our pipeline of potential projects, adding CO2 storage licences in Denmark, Norway and the UK.
Located in the UK’s most industrial and emissions-intensive region, with the ability to reuse existing infrastructure and a robust and scalable CO2 storage system close to European markets, Viking is a strategically and cost-advantaged project. Viking aims to transport and store up to 15 mtpa of CO2 by 2035. Its gross storage resource increased to 417 million tonnes (2023: 300 million tonnes) as at year end 2024. This follows the addition of the storage resources of two new CCS licences in Viking’s vicinity awarded in 2023. In Spring 2025, Viking reached two key milestones, FEED and development consent was granted for the onshore pipeline.
In December 2024, Harbour together with its partners announced a final investment decision for the Greensand Future project, marking Harbour’s and Denmark’s first CCS project to reach FID. Harbour has a 40% interest in this pilot-scale project, operated by Ineos. Greensand Future is a small, short cycle project with commercial returns, in part driven by the ability to reuse existing infrastructure and defer decommissioning at the Nini field. The project has been awarded an EU Innovation Fund Grant and is targeting first injection from 2026 at the rate of around 400,000 tonnes per year. CO2 will be shipped from the Port of Esbjerg in Denmark to the unmanned Nini platform – which Harbour also has a 40% non-operated interest in. CO2 will then be injected via a repurposed former oil producer into the Nini reservoir. Greensand could be the first CO2 storage facility in operation in the EU, supporting Denmark and the EU’s climate objectives. Read more about the Greensand project.
Harbour also has an interest in the cost-advantaged, onshore Greenstore CCS project in Denmark, which is being progressed through the appraisal work programme. Harbour has a 40% operator interest, with Ineos as our non-operated partner alongside the Danish state.
In Norway, Harbour has a 60% operated interest in the Havstjerne CO2 storage licence and a 60% operated interest in the Luna CO2 storage licence and was awarded an operated interest in the Kaupang CCS licence, alongside partner Equinor in December. The Havstjerne license drilled a successful exploration well in Q2 2025 confirming a valid store of high quality.
Harbour is progressing with early-stage engineering and concept studies for the development of CO2 transportation hubs at Wilhelmshaven in Germany, together with partner HES International, and at Immingham in the UK, with Associated British Ports.
