2. Chemical reaction
Coal
Gaseous CO2
Solid Carbonate
ΔH = 11,1 MJ/kg CO2
80%
ΔH = 2,7 MJ/kg CO2
20%
“The ground energy state of carbon
is a mineral carbonate”
Olivine:
Mg2SiO4 + 4CO2 + 2H2O => 2Mg2+ + 4HCO3
- + SiO2
[∆H = -239.2 kJ/mol]

13. GreenSand
Scaling up sales (=> lowering prices)
More projects
Selling CO2 credits (to be used in demonstration projects)
More science support (Deltares, NIOZ, Wageningen etc.)
