How CCS Works
Storage
The geology of the central north sea seabed is particularly suited for storing CO2 we have a good understanding of its geology because of 40 years of oil & gas exploration & production. As these oil and gas fields approach the end of their useful life they provide excellent resources for CO2 storage.
Saline aquifers
There are also porous rocks filled with very salty water called saline aquifers. These could be the ultimate place to store CO2, because above them is a thick layer of impermeable cap-rock which will keep the CO2 in place.
Geological studies have shown that these saline aquifers are vast, with the potential to hold all of Europe's CO2 emissions well into the next century.
