    The north sea oil fields are huge, and mostly empty now. They also have the infrastructure already built for gas extraction/injection.

    Makes sense as a location for a trial in that area.

      wow so they’re ‘storing’ it in the ‘empty’ oil fields? Sounds a lot like Enhanced Oil Recovery (EOR) to me.

        Because it is:

        There are four main EOR techniques: carbon dioxide (CO2) injection, gas injection, thermal EOR, and chemical EOR. More advanced, speculative EOR techniques are sometimes called quaternary recovery.[4][5][6][7] Carbon dioxide injection, known as CO2-EOR, is the most common method. In this method, CO2 is injected into a depleted oil field and is mostly left underground.

        CO2-EOR is usually performed using CO2 from naturally occurring underground deposits. It is also sometimes performed using CO2 captured from the flue gas of industrial facilities. When EOR is done using CO2 captured from flue gas, the process can prevent some emissions from escaping. However, there is controversy over whether the overall process is beneficial for the climate. EOR operations are energy-intensive, which leads to more emissions, and further emissions are produced when the recovered oil is burned.

        Used to extract fossil fuels, the field is now getting a second lease on life as a means of permanently storing planet-warming carbon dioxide beneath the seabed.

          If you take them by their word, it sounds perfect.

          I’m worried about Ineos’ ulterior motives. It would not take a lot of change or investment to start up EOR there if any drilling equipment is still in place.
