A novel gas combustion method removing the need for expensive gas separation has been successfully scaled-up. The novel method has gas-to-steam efficiency penalties much lower than alternative CO2 capture technologies, as well as a CO2 avoidance cost reduced by 60 % compared to amine scrubbing. The consortium is already looking to extend it to biomass combustion.
Although cleaner than crude oil or coal combustion, current methods for combusting natural gas still generate CO2 as part of a flue gas mixture including nitrogen, water vapour and other substances.
