MONTREAL, QC (August 20, 2025) — Deep Sky, the Montreal-based carbon removal project developer, has accomplished North America’s first underground CO₂ storage via Direct Air Capture (DAC) with CO₂ captured by Skyrenu, a Quebec-based DAC company. The breakthrough was achieved at Deep Sky Alpha, Canada’s first carbon removal commercialization centre, located in Innisfail, Alberta.

In a major milestone for the Canadian carbon removal ecosystem, Skyrenu’s DAC unit pulled CO₂ directly from the atmosphere and, in partnership with Deep Sky, permanently stored it underground. This marks the first time on the continent that CO₂ captured by a Canadian-developed DAC technology has gone through the full carbon removal cycle.

“We’re incredibly proud to lead the way as the first Quebec-based DAC technology to capture CO₂ for permanent storage in North America,” said Gabriel Vézina, Skyrenu CEO. “Our partnership with Deep Sky is a powerful example of how to accelerate DAC to climate-relevant scale. Deep Sky’s ability to integrate the full value chain—from CO₂ capture to sequestration—perfectly complements Skyrenu’s focus on designing and producing high-performance DAC units. Together, we can deliver impactful projects faster, generate high-quality carbon removal, and set a new benchmark for the industry. This first win proves that we have the model to lead the way in Canada and beyond.”

Skyrenu’s DAC unit was deployed at Deep Sky Alpha, the world’s first cross-technology carbon removal centre powered by solar energy. With the capacity to remove 50 tonnes of carbon dioxide per year, Skyrenu’s DAC unit is among a select group of technologies chosen to capture CO₂ at Deep Sky Alpha. Deep Sky selected Skyrenu’s technology for its potential to deliver low-cost CO₂ capture. Designed to accelerate the path from prototype to commercialization, Alpha enables leading carbon removal developers to validate, scale, and generate high-quality carbon removal credits in a real-world environment.

“This is exactly what Deep Sky Alpha was built for,” said Alex Petre, Deep Sky CEO. “A product of Sherbrooke University, Skyrenu’s achievement shows that Canadian climate tech can lead on a global stage and that carbon removal is ready to scale today.”

As governments and corporations look to meet net-zero goals, Skyrenu’s successful deployment underscores the importance of homegrown climate solutions that are permanent, measurable, and ready to scale. High-quality CDR is essential for achieving net zero emissions goals and mitigating the impacts of climate change.
