Could ice-like cages be used to trap carbon dioxide underground?

Ice-like "cages" of gas trapped underground may offer a safe and efficient way to reduce global warming. Researchers are investigating the potential for permanently storing carbon dioxide in geological reservoirs, by locking the global-warming gas within solid, cage-like structures called hydrates.

Two U of C researchers are investigating the potential for permanently storing carbon dioxide in geological reservoirs, by locking the global-warming gas within solid, cage-like structures called hydrates.

“A main attraction of utilizing hydrates is CO2 storage, including in some depleted gas reservoirs near oilsands operations in northern Alberta,” says Mehran Pooladi-Darvish, professor of chemical and petroleum engineering in the Schulich School of Engineering.

“Once you get the CO2 into a reservoir that has the right conditions and it contacts the reservoir water and forms hydrates, it’s in a pretty stable form,” says Jocelyn Grozic, associate professor of civil engineering at Schulich.

The Alberta government has committed $2 billion to develop carbon capture and storage (CCS) projects, to reduce the industrial CO2 emissions that contribute to global warming and climate change.
