Kathairos hits million-tonne milestone for CO2 reduction at oil and gas sites

Calgary’s Kathairos has scrubbed the equivalent of one million tonnes of carbon from the atmosphere, the company announced on Monday. It’s a milestone that the cleantech company says validates its technology’s scalability. The news: Kathairos replaces methane-rich natural gas with liquid nitrogen at oil and gas sites that use pressured gas to power and control valves and regulate pressure.
