Findings from recent Pacific Northwest National Laboratory experi­ments confirm carbon dioxide injected into deeply buried basalt formations can be effectively trapped by the relatively rapid formation of stable carbonate mineral compounds. A key discovery by researchers at the Pacific Northwest National Laboratory is that these carbonate minerals form in a relatively short period of time after carbon dioxide injection, which should enhance long-term retention. These results verify their hypothesis that in situ mineralization rates are quite promising and that field testing of carbon dioxide storage in these formations should be accelerated.
