In line with Denmark's 2020 Climate Act, CO2 capture and storage (CCS) take center stage, all set to steer the nation toward its climate objectives.
CCS is short for Carbon Capture and Storage
CO2 is frequently emitted from substantial point sources and industrial sectors that prove challenging to abate or transition in the short term. These emissions stem from activities like combusting in district heating plants, converting waste to energy, producing cement, refining oil, and operating biogas plants.
The captured CO2 is liquefied for convenient transport from the emitter source to a geological storage site, whether by ship, truck, or pipeline.
CO2 is injected through boreholes into sand layers buried over one kilometer deep underground. Within these layers, CO2 mingles with saltwater in the tiny spaces between sand grains. Ensuring a secure seal, thick clay layers deposited above the sand effectively prevent CO2 from escaping.
To monitor CO2 within the geological storage complex, a comprehensive data collection program is conducted throughout its active lifespan. This includes performing seismic measurements and installing observation wells, ensuring continuous and attentive monitoring.
