Quote:\u00a0 “”Cement production is not carbon intensive solely due to energy use, but because heating limestone (CaCO\u2083) creates lime (CaO) and carbon dioxide (CO\u2082). Even completely carbon-free energy cement production would contribute about 5% of the total global CO\u2082 emitted annually, at current levels of cement production. Cement will not be decarbonized without addressing both the energy source and chemical process.””<\/p>\n\n\n\n
However I believe the following is possible. Instead of heating the limestone with natural gas, it will be heated with electricity. This allows all of the gases from the limestone to be captured and the CO2 and other greenhouse gases to be captured and stored underground. <\/p>\n","protected":false},"excerpt":{"rendered":"
