Slide 7. What is Sequestration?
Reduction of anthropogenic CO2 requires some combination of efficiency and conservation, switching to cleaner alternatives and/or capture and long-term storage (sequestration). Sequestration options include terrestrial, oceans and geologic. Terrestrial options have certain volume and storage-time restrictions. Oceanic options have promise, but must consider life in deep ocean environments and possible sudden releases. With obvious bias as a geologist, geologic options, including enhanced oil recovery and brine reservoirs, have great volume potential, are perhaps the most permanent and least risky.
