By injecting hydrogen into its cement kilns as a catalyst, CEMEX may optimise the combustion process and increase its use of alternative fuels, decreasing its use of fossil fuels. The use of lower-carbon fuels is an essential lever for the company's 2030 goal to reduce CO2 emissions in cement production by more than 47%. In September 2022, CEMEX reached an all-time high of 34% alternative fuels substitution rate.
"Hydrogen is a key technology to accelerate the implementation of our climate action roadmap," said Ricardo Naya, president of CEMEX Mexico. "With this project, we expect to increase alternative fuels consumption in our kilns by 8 to 10 per cent."
CEMEX is a pioneer in adopting hydrogen technology in the building materials industry, with successful projects since 2019. As of 2021, the company uses hydrogen in all its European plants and recently inaugurated a similar project in the Dominican Republic. The company expects to continue scaling its use in other operations worldwide.
CEMEX is also working with several partners to discover and pilot breakthrough technologies for hydrogen to be used as a low or zero-carbon primary fuel source in cement production.
