... Government-supported demonstration of CO2 capture projects, integrated with transport and storage technologies, can further the deployment and replication of CO2 capture technologies. These demonstrations enable modularization of equipment at scale that may reduce construction costs, increase capture efficiency as improved technologies become available to substitute for current ones, and provide operational data that can build confidence with project investors and reduce financing risks.
