One of the best ways to mitigate the effects of carbon dioxide (CO2) emissions is to capture and sequester those emissions in underground geological formations for permanent storage. The United States has an estimated storage capacity of 3,900 Gigatons of CO2 within approximately 230 candidate geologic storage reservoirs, equal to 600 years of CO2 storage at current emissions levels.
In addition to its cost competitive position, GreatPoint Energy’s technology offers an attractive means to address climate change by enabling the efficient capture and sequestration of CO2 from its hydromethanation process. Unlike conventional gasification, for which carbon capture adds significant additional cost, energy loss, and complexity, hydromethanation intrinsically captures nearly all of the CO2 and other impurities found in coal, petroleum coke and biomass and makes it available for value-added use or long-term storage in underground geological formations.
As a result, it is both possible and desirable to locate production facilities in regions where CO2 can be sold and safely sequestered using currently available commercial EOR to boost oil and gas extraction. GreatPoint Energy sees this as one of the principal advantages of its technology.
A broad application of EOR using CO2 produced by GreatPoint Energy would safely sequester this greenhouse gas to help prevent climate change.
