The consortium will now file a grant application with Denmark’s Energy Technology Development and Demonstration Program. If the application is successful, the consortium targets starting work by the end of 2021, with the offshore injection pilot taking place in late 2022.

Mads Weng Gade, head of country, Denmark and commercial director at Ineos Energy, said: “We are taking this step by step. We now have the consortium in place, and if we are successful in receiving ongoing support from the Danish Government and advisory board, Greensand will be able to take another important step forward in supporting the Danish Climate Strategy.”

The primary objective of the Greensand project is to safely and permanently store potentially up to 8 million t/y of CO₂ in the Ineos-operated Siri area in the Danish North Sea. Ineos said the project recently cleared a major hurdle as international classification organization DNV independently certified that the Nini West field is conceptually suitable for injecting 450,000 t/y of CO₂ per well for a 10-year period, and that the gas can be contained safely within the subsea reservoir.

A final investment decision is expected to be taken in the second half of 2023 after proof of concept. The project is estimated to take around two years to execute, meaning that CO₂ storage could be operational from around 2025. Plans are for the storage of 500,000 to 1 million t/y of CO₂ initially, increasing to between 4 million and 8 million t/y by 2030, meaning that the Greensand area could account for all of the CO₂ storage proposed in the Danish Climate Program.
