Engineers develop scalable process to decarbonize cement …

The ZeroCAL approach, which can be integrated within the existing cement-production process, uses limestone feedstock to produce calcium hydroxide — which emits no carbon dioxide when burned to produce lime for cement. Byproducts of the process include hydrogen gas, which can be used as a clean-burning fuel to heat cement kilns.

What is Calcium Carbonate Limestone?

An example is when slaked lime (calcium hydroxide) is mixed into a thick slurry with sand and water to form mortar for building purposes. When the masonry has been laid, the slaked lime in the mortar slowly begins to react with carbon dioxide to form calcium carbonate (limestone) according to the reaction: Ca(OH)2 + CO2 → CaCO3 + H2O.
