China’s carbon neutrality target is building momentum for carbon capture, utilization, and storage (CCUS), by which the power sector may attain faster decarbonization in the short term. However, an overall CCUS pipeline network blueprint remains poorly understood. This study, for the first time, links the China TIMES model and ChinaCCUS Decision Support System 2.0 to assess representative CCUS layouts for the power sector toward carbon neutrality, with the level of deployment and the maximum transportation distance from emission sources to storage sites considered. The total length of the proposed layouts under the low, medium, and high levels of deployment are about 5100, 18,000, and 37,000 km, with the annum CO2 captures of 0.4, 1.1, and 1.7 Gt, respectively, whereas pipes of medium diameters (12, 16, and 20 in) account for the majority in all three plans. As the deployment rate increases, the layouts generally spread from Northeast, North, and Northwest China to East, South Central, and Southwest China. However, some local exceptions take place considering terrain areas that the pipeline passes through. In addition to engineering guidance, this assessment also illuminates the opportunity for improving the efficiency of CCUS based on carbon pricing.

“…In general, within a certain geographic space, numerous scattered emission sources and one or more storage sites are connected by a pipeline network, which could be integrated into a CCUS cluster. There are still several issues to be solved for large‐scale CCUS deployment in a full‐chain CCUS cluster, such as selection of CO 2 emission source types and location, general geographical environment of transportation, and specific geological conditions of storage sites 6 . In the future, a challenge for CCUS large‐scale commercialization is to seek suitable storage sites for CO 2 emission sources within a reasonable distance.…”

Carbon capture, utilization and storage (CCUS) is a critical technology option in achieving large-scale CO 2 mitigation for power and industrial sectors. A full-chain CCUS cluster could be formed based on numerous scattered capture sources and one or more storage sites connected by a pipeline network. Reasonable source-sink matching planning for a full-chain CCUS cluster could substantially reduce the system overhead. However, most of the previous studies could hardly address the dynamic source-sink matching planning problem of a full-chain CCUS cluster with multiple types of emission sources and sinks during multiple periods. Therefore, the objective of this study is to investigate an optimized source-sink matching scheme within a CCUS cluster through developing an optimization-based CCUS source-sink matching model. The proposed model is based on multistage mixed integer linear programming techniques with the objective of least-cost strategy; thus, it can deal with dynamics of capacity expansion associated with CCUS activities. The developed method is then applied to a CCUS cluster facing long-term dynamic planning issues. The modeling results suggest that the optimization-based CCUS source-sink matching model is applicable in reflecting dynamics of time, scale and location of CO 2 capture, transportation and storage within a CCUS cluster. The obtained solutions can provide decision bases for formulating an optimal planning scheme of a full-chain CCUS cluster under evolving reduction targets or constraints.

“…Fossil fuel combustion releases carbon dioxide (CO 2 ) into the atmosphere in large quantities, which contributes to the “greenhouse effect” . To meet the goals of carbon neutrality and sustainable development, it is imperative to abate the dependence on fossil fuels, shift to renewable energy (e.g., light, electricity, wind), and implement CO 2 capture and utilization. − The electrocatalytic CO 2 reduction reaction (CO 2 RR) technology offers an avenue to convert captured CO 2 molecules to high value-added chemicals through renewable electricity. − This technology shows a very promising strategy for simultaneously storing abundant renewable energy while closing the carbon cycle (Figure ). , …”

Electrochemical CO2 reduction simultaneously achieves conversion and storage of electrical energy as chemical energy through carbon recycling. Electrocatalysts with single-site and high efficiency for CO2 reduction have recently attracted much attention. In this review, the rational design strategies of single-site metal catalysts (SSMCs) for CO2 reduction are summarized. Particularly, we present the microenvironment engineering of SSMCs which entails atomic-scale design and nanoreactor construction. We further discuss the catalytic mechanisms, effects of the types, and coordination environments among metal species on tailoring catalytic activity and those nanoreactor features toward high-performance electrochemical CO2 reduction. Finally, we overview the current challenges and prospects of single-site metal catalysts for electrochemical CO2 reduction.
