What are the main challenges of CCUS?

    The main challenges include high costs, energy requirements, public acceptance, and ensuring long-term storage safety.

    CCUS faces several challenges. The technology is expensive, both in terms of initial setup and operational costs, which can be a barrier for widespread adoption. The process is energy-intensive, which can offset some of the benefits if the energy source is not renewable. Public acceptance is also a concern, particularly regarding the safety of CO2 storage. Ensuring the long-term integrity of storage sites to prevent leaks is another critical challenge, requiring rigorous monitoring and regulatory frameworks.
