Advances, challenges, and perspectives for CCUS source-sink matching models under carbon neutrality target

Abstract

With the widespread popularity of carbon neutrality, the decarbonization approach using carbon capture, utilization, and storage (CCUS) has grown from a low-carbon utilization technology to an indispensable technology for the entire global carbon-neutral technology system. As a primary method to support CCUS research, source-sink matching models face several new demand-oriented challenges. Comprehensive research and in-depth insights are needed to guide targeted capability upgrades. This review evaluates the advances, challenges, and perspectives of various CCUS source-sink matching models developed in the past 10 years. We provide an integrated conceptual framework from six key attributes relating to mitigation targets, carbon sources, carbon sinks, transportation networks, utilization, and integration (synergy). The results indicate that previous models have effectively deepened our understanding of the matching process by targeting various CCUS-related issues and provided a solid foundation for more robust models to be developed. Six perspectives are put forward to outline research and development prospects for future models, which may have meaningful effects for advancement under emerging carbon neutrality targets.

Advancing “Carbon Peak” and “Carbon Neutrality” in China: A Comprehensive Review of Current Global Research on Carbon Capture, Utilization, and Storage Technology and Its Implications

“…CCUS technology is paramount in carbon neutrality as a foundational element in realizing China’s carbon neutrality objectives. Its significance resonates across multiple dimensions: CCUS technology serves as the exclusive technical avenue for achieving net-zero emissions stemming from fossil fuels; it represents an indispensable precondition for incorporating coal-fired power generation within the framework of zero-carbon electricity peak management; it offers a feasible technological remedy for the intricate process of decarbonizing industries such as steel and cement; and it emerges as the primary pathway for securing nonfossil carbon feedstocks in the forthcoming era . Despite the profound import within research and practical implementation domains, it remains relatively less familiar to the general populace.…”

A low-carbon evaluation method for urban "source-network-load-storage" integrated power system

“…With the proposal of the "dual carbon" goal, the power system is rapidly transitioning to a low-carbon model dominated by new energy generation. The urban power grid is constantly deepening in terms of energy cleanliness, energy efficiency, consumption electrification, and grid load interaction [1][2][3][4]. How to quantitatively evaluate the low-carbon development level of the new power system is of great significance for guiding the sustainable and low-carbon construction of urban power grids.…”

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

“… 26 Technological progress is also taken into account to better estimate the dynamic cost of a global CCUS layout complying with the 2°C goal. 27 Focusing on the potential contributions of CCUS to NETs and clean fuel supply, 28 comprehensive infrastructure blueprints complementary to BECCS deployment 29 , 30 and low-carbon production of energy carriers (including hydrogen, 31 , 32 methanol, and ammonia 33 ) are also discussed in some countries and regions.…”
