In North China, about 88% of the CO 2 captured by power plants is transported to the Bohai Bay Basin for storage; the average transportation distance is about 130 km and the maximum distance is 372 km. East China is the closest to the Subei Basin, although its storage potential for CO 2 -EOR is relatively small.
To our knowledge, this is the first attempt to display an optimal CCS planning using a source-sink matching model for achieving the 2 °C targets in China. We identified suitable coal-fired power plants for CCS retrofitting and the optimal plan for deploying CCS in the power sector in line with the 2 ℃ constraints.
In order to achieve the goal of "double carbon", in the medium and long term, it is imperative that the power industry directs its focus toward the utilization of clean coal power generation technology in the medium to long term.
The results show that the nationally unified energy storage co-deployment requirement, namely, 15% capacity ratio of renewable installation and 4 h duration, will negatively affect the economics of renewable generation, leading to an average cost increase in 15% and 21% for wind and photovoltaic generation, respectively.
At present, under the background of “double carbon”, the power industry confronts significant challenges in terms of transition. Of all power generation forms, coal-fired power generation assumes a pivotal position in China's energy mix and thus plays a decisive role in the industry's transformation.
Therefore, reasonable consideration of the degradation of BESS can help ensure the overall reliability of power systems. In addition to BESS, other types of energy storage (such as hydrogen storage) will also play a key role in improving the flexibility of the power system .
