Calera has a chemical process in mind to sequester coal-plant C02 emissions in concrete. First, they would bubble hot, CO2-laden coal combustion stack gas through sea water. This would be done at the pictured Mossy Landing, coal-fired electricity plant. Calcium sulfate, and to a lesser extent magnesium sulfate, both of which are present at very low concentration in sea water, will react with the dissolv...
