“…157 More recently, Li et al estimated the CO 2 storage capacity in depleted gas reservoirs in the northern South China Sea to have a mid-value of 0.91 Gt. 158 Li et al have studied the sealing capacity of depleted oil and gas reservoirs. 159 They found that the caprock sealing capacity of a depleted oil or gas reservoir is reduced because of the lower CO 2 −water interfacial tension compared that of hydrocarbon−water.…”

In this paper, we review and analyze the salient features of the ongoing energy transition from a high to a low carbon economy. Our analysis shows that this transition will require decarbonizing the power, transport, and industry sectors, and the transition pathway will be country-specific. Carbon capture and storage (CCS) technologies will play a major role in this energy transition by decarbonizing existing and new fossil fuel power plants and the production of low-carbon fossil-fuel-based blue hydrogen. Blue hydrogen can be used for hydrogen fuel cell mobility in the transport sector and heat and feedstock in the industry sector. Current estimates show that there is adequate CO2 storage capacity in the world’s saline aquifers and oil and gas reservoirs to store 2 centuries of anthropogenic CO2 emission. However, the slow pace of CCS implementation is concerning and is due, in part, to too low of an oil price to make CO2-enhanced oil recovery profitable, lack of financial incentives for CO2 geological storage, low public acceptance, lack of consistent government energy policy and CCS regulations, and high capital investment. We propose several ways to accelerate CCS implementation. Among others, they include establishing regional CCS corridors to make use of economy of scale, public CCS engagement, carbon pricing, and using public–private partnership for financing, technology transfer, and linking up different stakeholders.

“…This study identifies 484 emission hubs, 7 offshore sequestration sites, and 106 onshore storage sites 45 , 46 ( Figure 3 E) to further examine the CCUS layouts in line with China’s carbon neutrality goal. In this research scope, a total storage potential of about 2469 Gt is regionalized and allocated to 113 potential storage sites, with onshore and offshore storage accounting for about 94% and 6%, respectively.…”

“…Li et al [41] used a multi-parameter dimensionless rapid screening model combined with reservoir composition simulation to evaluate the CO 2 -EOR and CO 2 storage potential of the HZ2-1 Oilfield in the Pearl River Mouth Basin, and concluded that the HZ21-1 Oilfield can implement CO 2 miscible flooding, CO 2 storage potential is 8.1-10.8 Mt. Li et al [42] assessed the potential of CO 2 sequestration in the major oil and gas reservoirs in the northern South China Sea, and showed that the four major geological basins had overall low, medium and high values of CO 2 storage potential of 1015.8, 1082.7 and 1151.5 Mt, respectively.…”

Carbon Capture, Utilization, and Storage (CCUS) technology has emerged as the bottom-line technology for achieving carbon neutrality goals in China. The development of Carbon Dioxide Enhanced Oil Recovery (CO2-EOR) not only increases revenue for high-investment CCUS projects but also enables permanent CO2 storage in the oil reservoir. However, the basin is used as the research object to evaluate the CO2 storage potential of the oil reservoir. The evaluation results are inaccurate and unable to support the implementation of later CCUS projects. Here, more accurate oil reservoir data is employed as the evaluation object. It is the first time at the national level to screen oil reservoirs to distinguish between CO2 miscible and immiscible, and evaluate the potential of CO2-EOR and CO2 storage in the reservoir. The research results show a total of 2570 suitable oil reservoirs in 4386 candidate oil reservoirs nationwide. About 1.26 billion tons of additional crude oil can be produced by CO2-EOR technology. This includes approximately 580 million tons of additional oil from CO2 miscible flooding and 680 million tons from CO2 immiscible flooding. The study further refines the CO2 geological utilization data and provides a theoretical basis for CCUS project site selection in China.
