Industrial decarbonization CCUS: Implementation of CCUS to lower industrial carbon emissions and meet sustainability targets.

Industrial decarbonization via CCUS is a necessity for achieving net-zero emissions, particularly in sectors where process emissions are inherent to production and cannot be eliminated through energy substitution. Key industries relying on CCUS include cement and lime production (where CO2 is released from the chemical breakdown of limestone), steel manufacturing (especially from blast furnaces), and the production of ammonia and other bulk chemicals. In these sectors, CCUS is one of the few viable, scalable solutions for deep emission reduction.

The CCUS application often involves capturing CO2 from concentrated flue gas streams, compressing it, and transporting it for geological storage. The economic feasibility of industrial CCUS is often enhanced by its integration into $\text{CO}_2}$ hubs, where the cost of transport and storage is shared. Successful industrial decarbonization through CCUS requires not only the retrofit of existing plants but also the design of new facilities to be "CCUS-ready," minimizing the cost and complexity of future capture technology installation.

Furthermore, the availability of low-carbon electricity is crucial, as the capture process itself requires significant energy, and this energy must be low-carbon to ensure the CCUS solution delivers genuine, lifecycle emission reductions. Ultimately, the deployment of CCUS allows these foundational, high-value industrial sectors to continue their operations and economic contribution while aligning with stringent climate targets.

FAQs on Industrial decarbonization CCUS

Q: Why is CCUS considered indispensable for the deep decarbonization of the cement and lime industries?
A: A significant portion of these industries' CO2 emissions are process emissions, released by the chemical reaction of raw materials (limestone) rather than fuel combustion, making alternative methods ineffective for the entire emission profile.

Q: What is the concept of designing a new industrial plant to be "CCUS-ready"?
A: It means incorporating space, utility connections, and structural provisions during the initial design and construction of the plant to significantly reduce the cost and complexity of installing carbon capture equipment later.

Q: In the context of industrial decarbonization, what is a crucial non-technical factor that determines the success of a CCUS project?
A: A crucial factor is a reliable and high-volume source of low-carbon energy to power the energy-intensive CO2 capture process, ensuring the overall project yields significant net-emission reductions.
