Mineralization.  Mineralization is the transformation of carbon dioxide into a solid mineral. It is one form of storage of captured carbon.  This is probably not something that your local city government is going to ever become greatly involved in, unless it has some great underground caverns just waiting to be filled up.  But it has become one of the talking points in the larger conversation of what to do with carbon if we are successful in capturing it in large volumes.  Because once carbon has been turned to a rock-like substance, it is not ever likely to leak back into the atmosphere. “Making Minerals – How Growing Rocks Can Help Reduce Carbon Emissions”. www.usgs.gov 3/8/19.  “Carbon Mineralization Pathways for Carbon Capture, Storage and Utilization”.  www.nature.com 2/26/21. “Setting Carbon Management in Stone”. www.news.mit.edu/2022/setting-carbon-management-stone-0317  “Mineralization: Turning Carbon Into a Mineral That Can be Permanently Stored Away”. www.shopify.com/about/environment/sustainability-fund/mineralization  “Invert and CarbonCure Sign the World’s Largest Purchase Agreement for Carbon Credits to Store CO2 Through Carbon Mineralization”. www.yahoo.com 4/12/22.
