Carbon Capture, Utilisation and Storage
Urban areas worldwide grapple with air pollution and carbon emissions, exacerbating climate change and deteriorating public health. One innovative solution addressing these critical issues is Carbon Capture, Utilisation, and Storage (CCUS). This technology offers a comprehensive approach to managing carbon emissions, transforming how cities can achieve sustainability goals while improving urban living conditions.
CCUS operates by capturing carbon dioxide (CO₂) emissions directly from industrial sources or the atmosphere. Once captured, the CO₂ is either utilised in various industrial processes or stored securely underground. The capture process typically involves chemical solvents or physical filters that absorb CO₂ from exhaust gases. The captured carbon is then compressed and transported to utilisation sites or storage facilities. Utilisation can include converting CO₂ into valuable products like fuels, chemicals, or building materials, thus creating a circular carbon economy. Alternatively, storage involves injecting CO₂ into geological formations, such as depleted oil fields or deep saline aquifers, ensuring it does not re-enter the atmosphere.
As urban areas continue to expand, so does their carbon footprint. By integrating CCUS technologies, cities can drastically reduce their greenhouse gas emissions, aligning with global climate targets and enhancing air quality. Furthermore, the ability to repurpose captured carbon into useful products fosters economic growth and innovation, creating new industries and job opportunities within the urban framework.
In addition, CCUS can play a pivotal role in supporting the transition to renewable energy. By mitigating emissions from existing fossil fuel infrastructures, cities can maintain energy stability while progressing towards a greener grid. This dual approach not only aids in the immediate reduction of urban emissions but also sets a scalable model for future carbon-neutral urban development.
