What carbon sequestration technologies exist?
• Geologic sequestration is the more popular method. It involves injecting carbon back into the fossil reserves from which is was mined, pumped, and piped. Often carbon gases are injected into oil and gas fields to increase fuel yields, called “enhanced oil recovery” (EOR). Research is being conducted in injecting CO2 into gas and oil reservoirs, coal bed methane recovery, and saline formation sequestration. • Terrestrial sequestration looks to capitalize on the fact that the global biosphere absorbs nearly 2 billion tons of CO2 a year. The DoE is focusing efforts in maximizing the carbon uptake of a number of ecosystems including forests, croplands (both agricultural and biomass fuels), deserts, and wetlands. Far more experimental and less concentrated, terrestrial sequestration is unlikely to be an easy way to increase biosphere carbon uptake. Unless, of course, we stop destroying the biosphere.
