Carbon capture, usage and storage (CCUS)
Although dismissed by environmentalists for use in the power sector given that renewable alternatives are increasingly cheap, carbon capture is seen as essential for rapidly decarbonising the cement industry, where process emissions of CO2 are unavoidable.
HeidelbergCement’s Lixhe plant in Belgium is home to the world’s first carbon capture pilot project for the sector, with plans afoot to bring the technology to commercial viability by the 2030s. It nevertheless depends on the emergence of a CO2 storage and transportation infrastructure that is likely to require serious government coordination and funding. CCUS is also being considered for the steel industry.
