VIRUM, Denmark – The Danish Energy Agency (DEA) will award DKK197 million ($29.85 million) to the INEOS-led consortium driving a carbon capture and storage development in the Danish North Sea.
Project Greensand is designed to support the Danish government’s goal of a 70% reduction in CO2 emissions in Denmark by 2030.
The main aim of the consortium is to store up to 8 MM metric tons of CO2 per year in the INEOS-operated Siri area. The project has three planned phases: appraisal, pilot (proof of concept), and full project execution.
The appraisal phase, already completed, was supported by Danish offshore field owners INEOS and Wintershall Dea, plus consortium members Maersk Drilling and GEUS, backed by the government.
DNV independently certified that the Nini West field is suitable for injecting 0.45 MM t of CO2 per year per well over a 10-year period, and that the subsurface reservoir can safely contain the CO2.
Planning for the pilot phase is ready to start, and FID for the full-scale project could follow in the second half of 2023. Carbon storage could be operational from around 2025.
The Siri area Palaeocene sandstone fields are said to lie at an optimal depth – 1.5-2.2 km (0.9-1.37 mi) – in a geologically stable area that has retained gas and oil for 10-20 million years.
