Deep Sky is multiplying partnerships in its quest to eliminate billions of tons of carbon.

The Montreal company announced on Monday an agreement with the very young (green) Quebec start-up Skyrenu, which has developed an avant-garde technology for direct capture of carbon in the air (DCA).

The Sherbrooke company will supply and install a CDA unit in 2024 with a capacity to eliminate 50 tonnes of CO₂ per year at Deep Sky's Alpha test site.

The two partners thus want to validate Skyrenu's technology with a view to commercial deployment in Canada.

Skyrenu has developed a modular system that combines direct air capture with a tailings carbonation process to trap CO₂ permanently in the rock, directly on mining sites.

This partnership "will allow us to demonstrate our technology in Quebec," commented Skyrenu President Gabriel Vézina by email. "This contract with Deep Sky will greatly increase the visibility of our company and its technology in Quebec, Canada and internationally."

Born out of the University of Sherbrooke, the company was created in 2021 based on work started in 2018 by its two co-founders, engineering professor Martin Brouillette and research engineer Gabriel Vézina.

The team of students who worked on the concept were winners of the 2021 XPRIZE Carbon Removal student competition (set up by Elon Musk).
