Hydrogen injection technology to be used reduce CO2 emissions at four Mexican cement plants

CEMEX are to implement hydrogen injection technology at four of their cement plants in Mexico as part of their Future in Action programme to achieve sustainable excellence and become a net-zero CO2 company.

By injecting hydrogen into their cement kilns as a catalyst, CEMEX will optimize the combustion process, increase the use of alternative fuels, and decrease the 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 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 8–10%.

CEMEX are one of the pioneers in the adoption of hydrogen technology in the building materials industry, with successful projects running since 2019. Since 2021, the company has used 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 are 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.

Future in Action is CEMEX’s programme to achieve sustainable excellence through climate action, circularity, and natural resource management with the primary objective of becoming a net-zero CO2 company. Through Future in Action, CEMEX have achieved record-breaking progress in reducing their carbon footprint over the past 20 months.
