Storage in the Bunter Sandstone in the 4-way dip closure known as Bunter Closure 36 (UKCS block 44/26) in the Southern North Sea. 5 well development of Bunter Closure 36 from an unmanned platform supplied with CO2 from Barmston via a 20” 160km pipeline. Final investment decision in 2023 and first injection in 2027. Capital investment of £254 million (PV10, 2015), equating to £0.9 for each tonne stored. The store can contain the 280Mt from the assumed CO2 supply profile of 7Mt/y for 40 years. Storage capacity is strongly linked to injection rate.
