Hydrocarbon fuels — be they coal, natural gas, petroleum, or biomass — release carbon dioxide (CO2) upon combustion. Carbon capture and storage (CCS) refers to the practice of collecting CO2, concentrating it, transporting it, and storing it in a manner that prevents it from mixing freely with the atmosphere. [1] Storage options include diversion into industrial processes, conversion into mineral carbonates, pumping to the depths of the oceans, and burial in deep geological formations. All phases of CCS (capture, concentration, transportation, and storage) face significant technological and economic challenges.
Many aspects of CO2 capture and storage (CCS) are still at the preliminary stages of development, and this mitigation approach requires sophisticated equipment, consumes extra fuel, and puts additional constraints on the location of facilities. The additional costs of a CCS system are substantial, and estimates depend on source, transport, and storage options. In most systems, CO2 capture is the most expensive step, but this cost should decline by 20% to 30% over the next few decades as new technologies become available.

The Author
Arnold J. Bloom became a botanist through a circuitous route. Upon receiving an undergraduate degree in Physics from Yale University, he spent several years developing computer models of the spread of air pollution over cities in the USA and Germany. He received a Ph.D. in Biological Sciences from Stanford University, where he also completed a two-semester course in Environmental Legislation at the Law School. He conducted postdoctoral research on the temperature responses of plants at the ... (Full Bio)
