A carbon capture project developed at the University of Sherbrooke will be among the technologies used by Deep Sky at its future CO capture and storage test site.₂, which should be launched in the Montreal region in the coming months.

The Montreal company Deep Sky has set itself the mission of extracting the main greenhouse gas, CO, from the atmosphere and oceans.₂, and sequester it in the soil.

It plans to create an “Alpha” site in Quebec to test different carbon elimination technologies with the aim of deploying them on a large scale.

Among the technologies to be studied is a facility designed by the start-up Skyrenu, which draws and captures CO₂ directly from the atmosphere.

The installation, developed by a team from the University of Sherbrooke, resembles five shipping containers stacked on top of each other. Each of these machines has a capacity to sequester 1000 tons of COXNUMX.₂ a year.

"It's a bit like a sponge through which you pass large volumes of air with fans, and this sponge is specially [designed] to retain CO₂ ", said Martin Brouillette, professor at the Faculty of Mechanical Engineering at the University of Sherbrooke.

"And when the sponge is saturated with CO₂, it is heated with steam to release the CO₂, which can be recovered in high purity,” explained the professor.

The CO capture system₂ Skyrenu's is a modular direct air capture device. It can therefore be deployed to capture CO₂ practically anywhere.

"We have to deliver our machine by the end of the year and, according to our information, the Deep Sky site should be in Montreal East," explained Martin Brouillette.
