The cement industry contributes about 5% to global anthropogenic CO2 emissions, making the cement industry an important sector for CO2-emission mitigation strategies. CO2 is emitted from the calcination process of limestone, from the combustion of fuels in the kiln, as well as from power generation. In such a case, a large proportion of the green hydrogen can be combined with carbon dioxide captured from the cement plant to produce synthetic methanol, which would then be refined into carbon-neutral synthetic kerosene. Besides, hydrogen and oxygen could be burned instead, replacing the fossil fuels entirely in heating chambers.
