Greensand CCUS, Denmark

Project Greensand works to reduce CO₂ emissions into the atmosphere. This is done by capturing CO₂ from the emitters, transporting, and storing the CO₂ in the subsurface of the North Sea in depleted hydrocarbon fields.

Kent has been selected to conduct screening studies covering the CCS Value Chain from the onshore capture sites, liquefaction, onshore storage, transportation, and offshore sequestration.

The scope includes studies to investigate the transportation of CO₂ and its storage potential in the depleted Nini Field in the Danish North Sea, which is expected to provide a storage capacity of between 0.45 to 1.45 mta million tons per annum (mta). The project will look at further expansion and use of other depleted fields and adjacent aquifers in the Siri Area (e.g. Cecilie, Nini East, Stine, and Siri), which may have a storage potential of up to 8 mta.

This study is aimed at:

• Capture & liquification: obtaining a better technical understanding of the components in the CCS value chain, screening the potential options to capture and liquefy CO2, differentiating them in terms of cost and risk and performing preliminary design these components.

• Transportation & Storage: screening the potential options for onshore & offshore transportation and injection of CO2 considering onshore gas or dense phase pipeline transfer, LP, MP, HP storage pressures into the Coastal storage site at Hirtshals, differentiating them in terms of cost and risk (as individual parts and as a whole chain) and performing preliminary design these components.

• 300km offshore Pipeline design for CO2 injection or the alternative of Ship offloading system.

This significant project adds to Kent’s portfolio of expertise in carbon capture and decarbonisation and brings together our multi-disciplinary capability in process and facilities, subsea and pipelines, flow assurance, naval architecture, and materials and corrosion.

Project Greensand is amongst the frontrunners of CO₂ storage projects in Europe and has the potential to support Denmark's wider CO₂ emission reduction target to reach a 70% CO2 reduction by 2030.
