Canadian Scientists Set Guidelines for Safe Carbon Capture and Storage

Article excerpt

Scientists set first carbon capture standards


REGINA - Scientists have released what they say are the first guidelines on the best way to store carbon dioxide underground so that 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.

"Any time that you've got a standard, that should ensure a lot of confidence that you're doing things properly because it's transparent, so now it's out in the open."

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.

The committee included representatives from Princeton University, the University of Alberta, Cenovus Energy Inc., Husky Energy Inc., the International Energy Agency, the U.S.-based Ground Water Protection Council and the U.S. Geological Survey. They've been working on the guidelines since 2009.

The guidelines don't specifically say how deep or where carbon should be stored, but detail what must be accomplished to do it in a safe way.

Dybwad likened it to cooking a chicken. She said the chicken has to reach a specific internal temperature to be safe to eat, but that temperature can be reached in many ways such as roasting or barbecuing. …
