REGINA -- Scientists have released what they say are the first guidelines on the best way to store carbon dioxide underground so it doesn't get back out.
The hope is that companies will want to follow the standards to help reassure the public about the safety of carbon capture and persuade doubters about its validity.
The guidelines, officially known as CSA Z741, include looking at geology and whether CO2 could flow through a possible fault underground. They also set out requirements and recommendations for burying the greenhouse gas in a safe way.
They are not mandatory, but more of a template for the industry, said Carmen Dybwad, CEO of the International Performance Assessment Centre for Geologic Storage of CO2.
"It's nice to be able to have, if you will, a guide, a standard to go through and say, 'Yes, we have made sure that we've looked at everything. We've looked at the issue of subsurface trespass. We've looked at the issue of fractures. We've looked at the possibility of setting a microseismic event,"' Dybwad said Thursday. "You know -- check, check, check, check, check.
The Regina-based centre and the Canadian Standards Association brought together more than 30 industry experts, researchers and regulators from Canada and the U.S. to write the standards.
