How to “Capture the Future by Utilization of the Past” in the Coming Revision of China CO2 Technology Roadmap?

A technology roadmap is the document that is generated by the technology road-mapping process. It usually identifies the critical system requirements, the product and process performance targets, and the technology alternatives and milestones for meeting those targets. In effect, a technology roadmap identifies alternate technology “roads” for meeting certain performance objectives. CCUS has great potential to reduce CO2 emissions substantially from the whole lifecycle of traditional energy-intensive industry at a large-scale. In this paper, we do not want to address how to generally make a CO2 technology roadmap. We are concerning about the gaps and suggestions which should be closed in the coming revision of China CO2 technology roadmap 2011. The paper presents a summary of latest situations of international and national CCUS technical roadmaps. Then, the challenges existed in the past and also emerged currently in China are proposed. Finally, some comments and suggestions for the coming version of China's CCUS technology roadmap are displayed to guide ongoing development of CCUS in China based on the development situation and challenges of China CCUS RD&D in the past and at the present stage.
