While carbon capture gets much of the attention in climate discussions, storage of CO2 is nonetheless a critical component of the overall climate challenge. Geologic formations potentially suitable for long-term carbon dioxide storage are relatively abundant and widely dispersed in the United States, and technologies for CO2 transportation and subsurface injection are well established on an industrial scale. But massive expansion of the present infrastructure will be required before enough CO2 can be stored to make a substantial difference in mitigating atmospheric concentrations. A variety of additional technical and nontechnical concerns also need to be addressed. |
