Decarbonising emissions-intensive industries requires technologies that can efficiently capture carbon dioxide (CO₂) and convert it into valuable products. Integrated carbon capture and storage approaches combine carbon removal and conversion into streamlined, energy-efficient systems capable of directly transforming CO₂ from industrial exhaust streams into chemical building blocks for sustainable fuels and carbon-based materials. By integrating capture and conversion within a single platform, these technologies reduce processing steps, minimise energy consumption, and remove the need for highly purified CO₂ feedstocks, improving practicality for large-scale industrial deployment. A major application is in sustainable aviation fuel production, where electrification remains challenging and alternative low-emissions fuels are urgently needed. Prototype integrated systems are being developed and tested under realistic operating conditions, with ongoing research focused on scaling pilot-level devices, improving durability and efficiency, and strengthening industry partnerships to support commercial adoption. Overall, integrated carbon capture and storage technologies provide a pathway toward circular carbon economies by enabling industries to transform emissions into fuels, chemicals, and materials while supporting the transition to low-carbon manufacturing and energy systems.
