CGC’s coal-assisted carbon capture and storage technology permanently buries carbon dioxide in unmineable coal seams through a safe and efficient process.
Practical Carbon Removal and Management
We capture and sequester carbon dioxide in unmineable coal seams, unlocking significant carbon sequestration potential at a greater scale and lower cost than previously imagined. We have revitalized and reinvigorated an old approach to putting carbon dioxide back in the ground where it belongs, in unmineable coal seams, through a safe and efficient process.
Coals act like carbon filters, preferentially absorbing carbon dioxide and thereby greatly reducing the need and cost of cleaning up flue gas to the purity required by conventional carbon capture and storage.
Our approach captures and stores carbon dioxide from a variety of emission sources, including power plants, industries like cement and paper, and ultimately from the atmosphere via emerging direct air capture (DAC) technologies, and permanently stores it underground.
Scalable Today
To meet mid-century climate goals, we need to capture and sequester 5-12 gigatons of carbon dioxide per year over the next 30 years – the equivalent of filling between 2-5 million Olympic-sized swimming pools with carbon dioxide. Presently, only carbon sequestration in geologic formations, where most of the carbon dioxide originated, can occur on a scale large enough to meet this need.
Additionally, only carbon buried in coal can occur at a cost that allows us to help meet the world’s climate goals. Those cost savings can accrue significantly over time, allowing us to do more with less. Burying carbon dioxide in coal, instead of deep sandstones and salt domes, also poses a lower geological risk, as these shallower, lower pressure, nanoporous formations are less likely to leak over time.
To successfully bury CO2 in unmineable coal seams at scale, CGC has perfected a unique approach to avoid geological damage and ensure these formations are utilizing their full potential to store carbon dioxide. Perfecting this approach entailed more than 20 years of R&D and field work and $35 million of investment.
