A pioneering ‘fingerprint’ test that hopes to build confidence in the geological storage of carbon dioxide (CO2) has been used for the first time in Canada.
The test, initially developed by researchers from Scottish Carbon Capture and Storage (SCCS), checks for leaks from carbon capture and storage (CCS) sites where man-made CO2 emissions are stored deep underground.
The technique has been used for the first time in Canada where it was conclusively used to investigate an alleged leak from CO2 underground at a farm in Saskatchewan.
The test concluded that the high levels of CO2 recorded on the farm arose from nearby wetlands – not as a leak from a nearby CCS site at Weyburn Oil Field.
