Linde and Heidelberg Materials plan to build and operate a large-scale carbon capture and liquid CO2 production facility at Heidelberg’s Lengfurt plant in Germany. The plant will be the cement industry’s first industrial-scale carbon capture and utilization (CCU) facility, according to Linde. The companies expect to begin operations at the CCU plant in 2025.
When complete, the plant will capture and liquify about 70,000 tons of CO2 per year at the plant that Linde will market as a feedstock for the chemicals and food and beverage sectors.
The CCU plant will use an amine scrubbing system specially developed for flue gases, according to Linde Engineering. The system will separate the carbon dioxide directly from the cement clinker kiln’s exhaust gas stream. The project also includes the use of purification and liquefaction, tanks for intermediate product storage and the construction of loading facilities.
”Climate protection is one of the most urgent challenges our industry is facing," says Jürgen Nowicki, executive vice president Linde plc and CEO of Linde Engineering. ”With this joint venture, two global leaders in their field are combining their expertise to create a solution that is as sustainable as it is economical. Following successful pilot applications, this industrial-scale facility will pave the way for sustainable cement production.”
