Storage of carbon dioxide (CO2) in a single geological formation could be optimised by injecting C)2 at more than one point simultaneously, according to a report published today.
The report is based on research led by Scottish Carbon Capture and Storage (SCCS) and used the Captain Sandstone beneath the Moray Firth as a case study to predict the performance of a potential CO2 storage formation when the greenhouse gas is injected at two points at the same time over three decades.
British Geological Survey project leader Maxine Akhurst, who led the project for SCCS, said: “Our study is one of the keys that will unlock the potential CO2 storage capacity underlying the North Sea and release this immense storage resource. Our results show that by using more than one injection site in a single sandstone operators can store greater volumes of CO2 compared to using a single injection site, so increasing Europe’s capacity to reduce greenhouse gas emissions.”
According to Scottish energy minister Fergus Ewing, carbon capture and storage (CCS) has the potential to be the most effective technologies to decarbonise the power and industrial sectors. Ewing added: “This research confirms how the huge CO2 storage resource potential beneath the North Sea can be optimised, which, combined with the infrastructure already in place, again reinforces the huge opportunity for Scotland around CCS. CCS can contribute significantly to the diversity and security of electricity supply, and also has a unique role to play in providing a continuing supply of flexible clean fossil fuel capacity that is able to respond to demand in the way that other low-carbon technologies cannot.
“Many experts have set out the case that in order to achieve global climate change progress CCS technology must be developed and implemented to generating stations. We will continue to work with a range of partners to firmly establish this cutting-edge technology in Scotland, making full use of our huge potential.”
