CaCO3 as an unlimited resource for carbon fuel production
"The Numbers: CaCO₃ vs. Oil & Gas
Resource Type Estimated Global Reservoir Size (in Carbon Mass) Equivalency in Metric Tons (Gt / Mt)
Calcium Carbonate (CaCO₃) ~40,000,000 Gigatons (Gt) 40,000,000,000 Million Tons (Mt)
All Fossil Fuels (Oil, Gas, & Coal) ~4,000 to 5,000 Gigatons (Gt)...[1]
Reference:
(1) CaCO3 (mining) = CaO + CO2 +179 kJ.
(2) CaO + CO2 (ambient) = CaCO3. -179 kJ
(3) CO2 + 3 H2 = CH2 + 2 H2O - 230 kJ.
(4) Water thermolysis with "enviloping reverse reaction" catalyst can reduce temperature of the thermolysis.[2]
