Canada’s Deep Sky to Pilot DAC Unit from Dutch Startup Carbyon

MONTRÉAL and EINDHOVEN, THE NETHERLANDS (February 14, 2024)Deep Sky, a Montreal-based gigaton-scale carbon removal project developer, and Carbyon, a Netherlands-based DAC company, have partnered to install carbon removal technology in Canada. As part of its partnership with Deep Sky, Carbyon will deliver and install two Air Processing Units (APUs), each with the capacity to remove 50 tons of CO2 per year.

As the world's first gigaton-scale carbon removal company, Deep Sky will operate Carbyon’s APU in its Labs innovation facility. The system will be installed in Québec in 2024, leveraging the region's vast renewable hydroelectric energy reserves.

Building upon decades of semiconductor technology developments, Carbyon uses a rigorously different approach compared to competing technologies: a fast swing process via a modular machine that contains a proprietary sorbent material, modified to rapidly and efficiently capture CO2 out of air.  Fast swing simply means ​​ultra-short CO2 adsorption and desorption cycles. While conventional materials need hours to capture CO2 from air, Carbyon’s process takes only a few minutes. This fast swing process is the key to lowering the energy consumption and enabling massive scaling of low-cost machines. The team’s ultimate goal is to deliver a cost of below €100 per ton of CO2 –  significantly lower than current rates.

Once in operation, the partners will monitor the performance of the APU at Deep Sky Labs. Data will be collected on the performance of the unit in terms of carbon dioxide removal (CDR), energy consumption, and more. Together, the partners aim to validate the technology for commercial deployment in Canada as part of Deep Sky's mission to develop Canada into a world-leading hub for carbon removal. 

“One of the many criteria that makes Carbyon stand out is the affordability and small footprint of its Air Processing Units,” said Damien Steel, Deep Sky CEO. “Its ultra-fast sorbent process increases CO2 capacity, decreases cost and energy consumption, ultimately producing a smaller unit which can be more easily transported and takes up less space to deploy. As a project developer sourcing units from around the world to produce the highest quality carbon credits for our customers, Carbyon was a natural choice.”

“From the high-tech region of Eindhoven, we’re thrilled to share our technology on a global stage at Deep Sky Labs,” said Hans De Neve, Carbyon Founder and CEO. “Carbyon exists to have a positive impact on the planet, and this partnership brings us one step closer to achieving our mission.”

Together, Deep Sky and Carbyon are committed to developing and deploying cutting-edge carbon dioxide removal (CDR) technologies. High-quality CDR is essential for achieving net zero emissions goals and mitigating the impacts of climate change. 

Powered by renewable energy, Deep Sky's facilities are strategically located in Québec, a region with an abundance of hydroelectric power, immense wind power potential and a vast territory with the rich geological makeup required for carbon capture.
