Several key issues for CCUS development in China targeting carbon neutrality

Abstract

Carbon capture, utilization, and storage (CCUS), as a technology with large-scale emission reduction potential, has been widely developed all over the world. In China, CCUS development achieved fruitful outcomes. CCUS gained further broad attention from the announcement of the carbon neutrality target by 2060, as CCUS is an indispensable important technology to realize carbon neutrality. It helps not only to build zero-emission and more resilient energy and industry systems but also provides negative emission potential. This paper discusses the new demand for carbon capture, utilization, and storage development brought by the carbon neutrality target analyzes the development status. As there remain various challenges of CCUS development, this paper focuses on several key issues for CCUS development in China targeting carbon neutrality: 1) how to reposition the role of CCUS under the carbon neutral target? 2) how shall we understand the technology development status and the costs? 3) what role shall utilization and storage play in future? 4) potential strategy applied to solve challenges of source-sink mismatch and resources constraints; and 5) new business model that suits large scale deployment of CCUS. This paper puts forward several policy suggestions that should be focused on now in China, especially to raise awareness under the vision of carbon neutrality that the role and contribution of CCUS are different, to accelerate the establishment of a comprehensive and systematic enabling environment for CCUS.

Subsidizing Grid-Based Electrolytic Hydrogen Will Increase Greenhouse Gas Emissions in Coal Dominated Power Systems

“…China's ability to utilize CCS technology is debated, with the feasibility and permanence of carbon storage uncertain due to the characteristics of China's sedimentary reservoirs. 32 Moreover, the lack of effective business models, CO 2 transport pipelines, and commercialized carbon capture technologies as well as insufficient incentives and regulatory measures bring challenges to the development of large-scale CCS projects. 33 Moreover, although coal-based hydrogen production is currently the primary source of hydrogen in China, there is currently no effort to pair CCS with coal-based hydrogen production.…”

Integrated CO2 capture and utilization: a review of the synergistic effects of dual function materials

“…15 In contrast, CCU uses the captured CO 2 to produce value-added chemicals and renewable fuels. 16 However, the CO 2 released from the capture unit must be extremely pure, and the required absorption and purification are energy-intensive. 17 To overcome these limitations, a new strategy combining CCU, referred to as integrated CO 2 capture and utilization (ICCU), has been proposed.…”

China’s multi-sector-shared CCUS networks in a carbon-neutral vision

“…Renewed interest in China’s CCUS deployment has also been largely triggered by the nation’s increasingly strong climate ambitions, especially the carbon neutrality pledge. 34 , 35 , 36 Considering the uncertainty of mitigation technology competition, representative CCUS layouts for decarbonizing China’s CFPPs are unveiled to satisfy diverse levels of CO 2 capture demand. 37 The impacts of CCUS deployment time and transport distance on the mitigation potential are also explored.…”
