It is a happy accident of geography that just 100km from the North east coast of Scotland is a sub-surface rock formation that’s perfect for storing CO2. And because the last fifty years have been spent mapping and testing the region in the search for oil and gas, it’s an area that is well understood by geologists.
Two and a half kilometres below the sea bed, under a several layers of impermeable cap rock, this porous sandstone formation is, according to geological experts, perfect for storing CO2 in a fluid state permanently and safely. There are only a handful of locations like this around the UK and none with the transportation infrastructure already in place. In fact, around a third of the UK’s total CO2 storage capacity lies within 50km of the St Fergus pipeline corridor.
Since the first North Sea oil came ashore in Cruden Bay in 1975, Scotland’s oil and gas workforce has developed a global reputation for their skills. Now, as the oil and gas extracted from the North Sea declines, those skills can be put to good use again, storing the CO2 that comes from the production of the essential goods we use in our daily lives.
