SkyRenu, founded in 2021 by Martin Brouillette and Gabriel Vézina, integrates Direct Air Capture (DAC) with rock carbonation to store CO₂ in Canadian mine tailings. Their system, powered by renewable energy, eliminates the need for CO₂ transportation while achieving high energy efficiency. After successful prototype testing in 2023, SkyRenu is scaling up its operations. As an XPrize finalist, they represent a promising and scalable solution for long-term carbon capture.
