Release date- 19062014 - On Friday 13 June, the Energy Minister, Michael Fallon, visited an innovative underground prototype project aimed at reducing the cost of fighting climate change and radically reducing carbon emissions into the atmosphere.

Carbon Capture and Storage (CCS) is a process of capturing millions of tonnes of carbon dioxide (CO2) from power stations and industrial facilities, and storing the CO2 offshore, deep under the sea bed.

The Muon Tomography project is led by Durham University and the University of Sheffield, also partnering with the University of Bath and with input from colleagues at NASA. Professor Cathryn Mitchell from the Department of Electronic & Electrical Engineering has been involved in the project, which is developing devices that use subatomic particles known as muons to monitor the stored CO2.

Based at Boulby Underground Laboratory, Boulby Mine on Teesside, the GBP1.75 million project involves housing prototype CO2 detectors to simulate offshore underground sites that may be used to store captured CO2 in the future. At a depth of over a kilometre, Boulby, a working potash and salt mine operated by Cleveland Potash Ltd, is the deepest in Britain.

The muons, which make up much of the cosmic radiation reaching the earth's surface, pass through solid objects and could therefore be used to monitor CO2 stored under the sea bed to make sure it is remaining stable.

Professor Jon Gluyas, of Durham Energy Institute, said: 'The muons begin life in the upper atmosphere, the result of collisions between cosmic rays generated in supernova hundreds of light years from Earth, and nitrogen or oxygen atoms. They penetrate through almost all surfaces and substances, much more powerfully than X-Rays and can be used to make three dimensional images of objects.

'This imaging - known as tomography - could be used to monitor CO2 held underground, or 'geo-stored.'

'CCS is a possible solution to preventing the emission of CO2 into the atmosphere by capturing it and compressing it into a fluid. This could then be stored underground, such as in the depleted oil and gas fields under the North Sea's bed. The process could reduce emissions from fossil fuel power stations by up to 90 per cent.

'Muon tomography could enable us to remotely check and track the geo-stored CO2 and so ensure the integrity of the site.'

He further added: 'We are delighted with the GBP647,000 contribution to this project by the Department of Energy and Climate Change (DECC) and thrilled to have the opportunity to show the Minister the project in action.'

Michael Fallon, Minister of State for Business and the Minister of State for Energy, said: 'It is fascinating to see how the innovative CO2 monitoring technology being tested at Boulby Potash Mine could help to reduce the costs of Carbon Capture and Storage.

'The UK is ideally suited to the development of a CCS industry with excellent storage potential in the North and Irish seas as well as world leading CCS research like this being undertaken by UK universities. We want to see a strong and successful CCS industry which has the potential to support a diverse energy mix and help us to achieve our climate change targets in a cost-effective way.'
