An Ottawa cleantech firm on a self-described mission to “turn dirty air into dollars” is turning investors’ heads with its groundbreaking technology that converts greenhouse gases emitted by heavy industry into products that can be used in everything from green building materials to toothpaste. Hyperion Global Energy says its patented system will be ready for market before the end of this year. Nearly a decade in development, the technology has caught the eye of industrial giants such as European cement producer LafargeHolcim. Hyperion, which is based out of Invest Ottawa’s accelerator at Bayview Yards, is now in talks to install prototypes of its “carbon recycling” modules in LafargeHolcim’s plants, where the system will collect CO2 from factory smokestacks and turn it into valuable materials such as calcium carbonate.
