Calcium Carbonate: Is It The "Secret Sauce" Of Carbon Capture?

"Researchers have now measured the energy changes among different forms of what is one of the most widespread minerals on Earth—from its messy noncrystalline forms to beautiful calcite crystals that could lock away carbon underground for thousands to millions of years.

“Calcium carbonate is the major long-term sink for atmospheric carbon dioxide,” says Alexandra Navrotsky, professor of ceramic, earth, and environmental materials at University of California at Davis.

"Steps to mitigate global climate change will likely include extracting carbon dioxide from power plant flues and the atmosphere and storing it underground, initially as a dense gas in old mines and depleted oil reservoirs that would eventually turn into solid, stable calcium carbonate through chemical reactions."
