Australia also has abundant coal resources and focuses on coal gasification as part of its COAL 21 program, which includes research on carbon sequestration as part of the national clean coal strategy. The objective is that Australia s vast coal reserves would remain a long-term, secure and cost-effective source of energy, but rather than burn the coal power plants would gasify that coal and capture and sequester the CO2 in geological formations. 

As a consequence of the realization that dissolution of magnesium- and calcium-containing sihcates controls carbon dioxide concentrations in the atmosphere over geologic time (e.g.. Equations (l)-(2)) and that such reactions may be important for subsurface carbon sequestration over human timescales, researchers have also become interested in the effect of dissolved inorganic carbon on dissolution. The indirect effect of CO2 species on dissolution of... 

Management of atmospheric carbon dioxide levels will require sequestration of carbon dioxide. Research and development into methods to cost effectively capture and geologically sequester carbon dioxide is required in the next 10 to 20 years.5... 

To meet the challenges discussed above, research opportunities for the chemical sciences may be envisioned in four areas. First, in carbon dioxide sequestration, an understanding is required regarding how molecular carbon dioxide interacts with various species present in coal mines or other geological formations where carbon dioxide might be stored. It is particularly important to understand...
