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 capturing CO2 and securely storing it in depleted oil and gas fields in the North Sea.

Greensand Future builds on the successful Project Greensand 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 Future aims to initiate storage operations into the INEOS-operated Nini field in the Danish North Sea at the end of 2025/early 2026, which will make Greensand Future the EU’s first operational CO2 storage facility intended to mitigate climate change. Once operational, Greensand Future aims to safely capture and permanently store 400.000 tons of CO2 each year as a start allowing for the gradual expansion of storage capacity as CO2 volumes increase with a potential to store 8.000.000 tons of CO2 per annum.

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 earlier this year, 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 Nordøfonden works to ensure reduction of emissions to the atmosphere.
