本研究では、中国の露天掘り廃鉱山に太陽光発電（PV）を設置した場合のライフサイクル全体の炭素削減ポテンシャルを定量化。結果、年間1.34-2.93 EJの再生可能エネルギーを生成し、278.85-613.79 MtのCO2削減が可能で、これは中国の石炭火力発電の5.9%-12.8%、2020年の炭素排出量の2.8%-6.2%に相当する。内モンゴル、新疆、山東などが高いポテンシャルを示し、PV+生態修復モデルの経済的実現性も確認された。
English
This study quantifies the life-cycle carbon mitigation potential of photovoltaic (PV) systems on abandoned open-pit mines in China. Results show that developing PV on such sites could generate 1.34-2.93 EJ yr-1 of renewable energy and reduce CO2 emissions by 278.85-613.79 Mt yr-1, accounting for 2.8%-6.2% of China's 2020 carbon emissions. Inner Mongolia, Xinjiang, Shandong, and other provinces are key regions. The 'PV+' ecological restoration model is economically feasible and supports China's dual carbon targets.

📄 Abstract（原文）
Amid increasing pressure to reduce carbon emissions and address the energy crisis, solar power has emerged as a key alternative to fossil fuels. China possesses extensive abandoned open-pit mines suitable for photovoltaic (PV) power development; however, their carbon mitigation and energy conservation potential remains largely underutilized. In this study, we develop an integrated model to quantify the life-cycle carbon mitigation potential of PV systems on these mines, combining PV power generation with ecological restoration of mine sites. The results indicate that developing PV systems on abandoned open-pit mines in China could generate 1.34-2.93 EJ yr-1 of renewable energy and reduce CO2 emissions by 278.85-613.79 Mt yr-1, accounting for 5.9%-12.8% of China’s coal-fired power generation and 2.8%-6.2% of its carbon emissions in 2020. Replacing conventional electricity with PV power yields greater carbon mitigation (611.63 t CO2 ha-1) than bioenergy alternatives, including biopower (102.96 t CO2 ha-1), ethanol (61.99 t CO2 ha-1), and biodiesel (17.13 t CO2 ha-1). Inner Mongolia, Xinjiang, Shandong, Hebei, Guangxi, and Yunnan were identified as key provinces with high renewable energy production and corresponding CO2 mitigation potential, collectively contributing 44%-45% of the total mitigation potential. Overall, an energy-oriented ecological restoration model, such as the “PV+” scenarios for abandoned open-pit mines, is economically feasible. This study provides geographically tailored information to help decision-makers optimize the use of multifunctional land resources, supporting the green transformation of the mining industry and advancing China’s dual carbon targets.
