日本語

中国を対象に、カーボンニュートラル経路の違いが大気質改善を通じて太陽光発電量に与える影響を統合モデルで定量化。再生可能エネルギー重視の経路では、BAU比で年間575億kWh（約51.8億ドル相当）の発電増加が見込まれ、その主因はエアロゾルと雲の相互作用であることを示した。バイオマスやCCS依存の経路では効果は約3分の1に留まる。

English

This study quantifies how alternative carbon-neutrality pathways in China affect solar PV output via air quality changes, using integrated energy-economy, meteorology-chemistry, and PV performance models. A renewable-focused pathway boosts annual PV generation by 57,526 GWh (US$5.18 billion) by 2060 versus BAU, driven mainly by aerosol-cloud interactions. Biomass or CCS pathways achieve only one-third of these gains.

📄 Abstract（原文）

Abstract Solar photovoltaic power is essential for achieving carbon neutrality, yet its output is highly sensitive to changes in air quality under future emission pathways. We integrate energy–economy, coupled meteorology–chemistry, and photovoltaic performance models to quantify how alternative carbon-neutrality pathways influence solar power generation via air quality changes in China. Here we show that a pathway emphasizing renewable-energy deployment yields the greatest air-quality improvements, boosting annual photovoltaic power generation by 57,526 ± 10,314 gigawatt-hours (GWh) relative to business-as-usual, equivalent to economic gains of US$5.18 ± 0.93 billion by 2060. These gains are driven primarily by aerosol–cloud interactions rather than aerosol–radiation interactions. In contrast, pathways relying on biomass or carbon capture achieve only about one-third of these gains. The largest gains occur in eastern and southern China, where electricity demand is highest. These findings highlight the importance of co-optimizing decarbonization and air-pollution mitigation to maximize the renewable energy benefits of carbon-neutrality strategies.
