Or follow us on Google News!<\/em><\/p>\n A few days ago I went deep on cement again, using an assessment of the processes of American clean cement startups to define the scope and magnitude of the problem, the chemistry and energy requirements of cement, why fixing it is critically important, and incidentally evaluate a couple of companies\u2019 offerings.<\/p>\n The CliffsNotes \u2014 FreeBookNotes in China is the closest approximation \u2014 of that deep dive is pretty straightforward. Limestone is incredibly cheap and widely spread because it\u2019s dead shellfish and precipitated calcium ions from long vanished oceans. Deposits hundreds of square kilometers and a hundred or more meters deep are near or on the surface all over continents globally.<\/p>\n We quarry limestone cheaply because it\u2019s a softer, sedimentary rock and exists almost everywhere…<\/p>\n<\/div>\n
