The MgCO2 Cycle
The MgCO2 cycle is a thermodynamic cycle in which energy is neither created nor destroyed but only lost through inefficiencies.
The Magnesium Thermodynamic Cycle (MgCO2 cycle)
The reasons why the Gaia Engineering tececology uses the MgCO2 cycle include:
- Magnesium has a low molecular weight as a result of which more CO2 is captured than in calcium systems as the calculations below show.
CO2/MgCO3 = 44/84 = 52% whereas CO2/CaCO3 = 44/84 = 43%
- Magnesium carbonates can be calcined at low temperatures easily using non fossil fuel energy thereby reducing inefficiencies
- At 2.09% of the crust magnesium is the 8th most abundant element
- Every litre of sea water contains about 1.29 grams of magnesium and magnesium carbonate will be abundantly available through the Greensols process.
Magnesium minerals are potentially also low cost and in Gaia Engineering will come from the Greensols process. The new Tec-Kiln technology from TecEco will enable easy low cost simple non fossil fuel calcination of magnesium carbonate with CO2 capture and re-use.
