To achieve the goal of carbon neutrality within the planned timeline, it is urgent to build a technical system that comprehensively supports the transition from a "high carbon society" to a "carbon neutrality society". Carbon Capture, Utilisation, and Storage (CCUS) are all efficacious means to reduce carbon emissions and strengthen carbon sequestration while also serving as important technical assurances for countries to achieve carbon neutrality. This study provides an overview of the research progress and application cases of CCUS, H transportation, CO2 network synthesis and integration, and related technical methods. The demonstrations of CCUS technology application and research progress can be summarised from the prism of capture performance assessment, utilisation approach research, environmental suitability inspection, etc. It evaluates the development of CO2 transportation in relation to the transportation economy, transportation safety, and CO2 recovery rate. The purpose of this study is to furnish a methodical reference for the construction of a carbon reduction system and promote the gradual realisation of carbon reduction goals in each stage.
