Is Canada too cold to capture carbon?

Ottawa-based company is working on new system that doesn’t use liquids that easily freeze

There’s growing interest in direct air capture technologies to mitigate climate change. But there’s a problem: most existing systems capture carbon with liquids that freeze easily.

“In Canada, they can’t run for most of the year,” says Vida Gabriel, co-founder of Terra-Fixing, an Ottawa-based company working on an alternative.

Terra-Fixing is developing a system specifically designed for cold climates and is planning a pilot in Fermont, Que. The tech is contained in a box about the size of a shipping container where a fan continually draws air in.

Instead of using liquids, the system catches carbon dioxide by passing the air over a mineral called zeolite. Once collected, the carbon could be sequestered below ground (the company is eyeing potential sites in the Arctic). The system will run on renewable power and have on-site carbon sequestration.

Gabriel points out that the Great White North is an excellent location for carbon capture with cold proofed technology. Heat makes molecules in the air move faster, “but as soon as you start to cool things off, they move less and they’re easier to capture.”

This work has garnered the attention of Klarna, a fintech company that’s contributing a total of $2.35 million (U.S.) toward new and promising climate solutions around the world. Terra-Fixing is planning to use the funding to accelerate its tech development and compete in the high-profile $100million Xprize for carbon removal, where it is one of the top 60 finalists.
