In Carbon Capture Utilisation & Storage, captured CO₂ can be permanently stored in stable forms. Storage options include mineralization into solid carbonates, geological storage in deep saline aquifers or depleted oil and gas reservoirs, and utilization pathways where CO₂ is converted into useful products. In laboratory systems, storage is often demonstrated through mineralization, where CO₂ reacts with alkaline solutions to form stable solids, ensuring long-term carbon containment.

CCUS helps prevent global warming by capturing CO₂ emissions at the source before they are released into the atmosphere. By reducing the concentration of greenhouse gases, CCUS directly lowers the overall carbon footprint of industrial processes and energy systems. When combined with renewable energy and efficiency measures, CCUS enables significant emission reductions while allowing existing infrastructure to transition toward low-carbon operation.

CCUS plays a critical role in clean energy transitions by addressing emissions from hard-to-abate sectors such as power generation, cement, steel, and chemical industries. It complements renewable energy by enabling low-carbon operation of existing assets, supporting hydrogen production, and enabling negative-emission pathways when paired with bioenergy. CCUS also provides a bridge technology while renewable and storage systems scale globally.

The key advantages of CCUS include significant reduction of CO₂ emissions, compatibility with existing industrial infrastructure, and flexibility across multiple sectors. It enables carbon recycling through utilization pathways, supports climate targets without immediate system overhauls, and provides valuable research and training opportunities. CCUS also accelerates innovation in sustainable fuels, materials, and long-term carbon management strategies.
