About us

The companies behind Greensand - the current storage license holders (IRIS) - are INEOS Energy Denmark, Harbour Energy and the Danish State Subsurface Resource Company Nordsøfonden.

Greensand works with several partners to ensure residual CO2 can be captured, transported to harbour sites, and sailed to the North Sea for permanent storage.

We are currently working with Port Esbjerg along with many other actors in the CCS value chain including biogas producers. We are continuously exploring new partnership opportunities which can help strengthen the CCS value chain - from capture, transport and storage.

INEOS Energy

INEOS is a global manufacturer of petrochemicals, specialty chemicals and oil products. In 25 years, the company has grown into a global player: its production network spans 183 sites in 26 countries throughout the world employing more than 26,000 people.

INEOS Energy operates the Siri field area and the South Arne and the Solsort in Denmark. INEOS operates the leading carbon storage project in Denmark – Project Greensand – which is a pioneering carbon capture and storage (CCS) initiative aimed at reducing greenhouse gas emissions by permanently storing captured CO₂ in depleted oil and gas fields in the North Sea.

Project Greensand builds on the successful pilot which, in March 2023, demonstrated for the first time the feasibility of cross-border, offshore CO2 storage across the full value chain - from capture to transport and storage. Greensand stores CO₂ in the INEOS-operated Nini field in the Danish North Sea, making Greensand the EU's first full-scale CO₂ storage site in operation. In its first commercial phase, Greensand transports and permanently stores up to approximately 400,000 tonnes of CO₂ per year, with the potential to expand to between 4 and 8 million tonnes annually as volumes of captured CO₂ increase.

At the same time, work is also underway to investigate whether it is possible and safe to store CO2 underground on land in Denmark, and in 2024, the Minister for Climate, Energy and Utilities awarded INEOS, Harbour Energy and Nordsøfonden an exploration licence for an area of the Danish subsurface in Jutland in the Gassum reservoir. The experience from Greensand will be included in the work to demonstrate safe storage also on land.

Harbour Energy

Since its creation in 2014, Harbour has grown to become one of the world’s largest and most geographically diverse independent oil and gas companies. Today, Harbour has significant production in Norway, the UK, Germany, Argentina and North Africa. Harbour benefits from competitive operating costs and resilient margins, and a broad set of growth options including near-infrastructure opportunities in Norway, unconventional scalable opportunities in Argentina and conventional offshore projects in Mexico and Indonesia. With low GHG emissions intensity and a leading CO2 storage position in Europe, Harbour remains committed to producing oil and gas safely and responsibly to help meet the world’s energy needs. Harbour is headquartered in London with approximately 5,000 staff and contractors across its operations and offices.

Nordsøfonden

Nordsøfonden is the Danish state company, tasked with generating value for Danish society by exploiting the potential of Denmark’s subsurface assets.

Nordsøfonden rests on two pillars: Production of oil and gas, thus helping to assure supplies of energy and raw materials. At the same time, Nordsøfonden is the state participant in all licences for underground carbon storage, where Nordsøfonden works to ensure reduction of emissions to the atmosphere.
