Germany: A consortium of Mexico-based Cemex subsidiary Cemex Deutschland, Uckerwerk Energietechnik subsidiary Enertrag and hydrogen specialist Sunfire has announced a cement industry decarbonisation project called Concrete Chemicals. The project will see sequestered CO2 combined with hydrogen to produce hydrocarbons for use as cement fuel. The consortium has submitted a funding application to the German Ministry for Environment, Nature Conservation and Nuclear Safety for a trial at Cemex’s Rüdersdorf, Brandenburg, cement plant. This would help in the realisation of the plant’s 2030 carbon neutrality target. Alongside a 5000t/yr demonstration plant, the site will have a green hydrogen plant, supplied by Sunfire. When commissioned in 2025, the plant will produce synthetic fuels and other hydrocarbon fractions. The consortium is also investigating a methanol synthesis route using synthetic gas.
Europe, Middle East and Africa regional president Sergio Menendez said “We support the urgency of action to address the climate challenge and have committed to a 55% reduction in CO2 from our 1990 baseline in our European operations by 2030. Together with our industry partners, we can collectively transform ourselves into a CO2-neutral world. Concrete Chemicals is a promising project.”
