1.	Hazeldine, RS. Carbon capture and storage: How green can black be? Science. 325:1647-1652, 2009 This is one in a series of artices from a Special Section of the top-flight journal Science. A particular strength of this article is its section on technical challenges for the major stages of CCS, including capture, transportation and injection/sequestration. The article has outstanding figures, one of which is used in this webpage.
2.	Rubin ES, Mantripragada H, Marks A, Versteeg P, Kichin J. The outlook for improved carbon capture technology Progress in Energy and Combustion Science. 38:630-671, 2012 This review article's initial sections, which cover the three major approaches to carbon capture, provide excellent explanations of these technologies. Accompanying figures are very helpful for understanding the technologies. There are also interesting sections on the energy penalty for and costs of carbon capture. The article then becomes more technical in its coverage of the various approaches to carbon capture and their outlooks.
3.	Plains CO2 Reduction Partnership (PCO2R) This website, which is maintained by the University of North Dakota Energy & Environmental Research Center, reflects work of the Plains CO 2 Reduction (PCOR) Partnership. PCOR is one of the seven regional partnerships funded by the Regional Carbon Sequestration Partnership Initiative of the U.S. Department of Energy. PCO 2R produces the PCO 2R Partnership Atlas, a very professional publication that uses maps and schematic figures to explain CCS.
