中国の化学産業脱炭素化において、風力・太陽光偏重戦略ではなく、水力・原子力・バイオマス等を組み合わせた多様なエネルギー供給が、コスト削減とリスク軽減に有効であることを、空間明示モデルで実証。2060年までに年間コスト2180億元削減、限界削減費用が3160→1401元/tに低下し、電解槽・蓄電需要も大幅減。地域別の移行戦略の重要性を提唱。

Using a spatially explicit model, this study shows that diversified energy supply (hydropower, nuclear, biomass) safeguards cost-effective and risk-mitigated chemical decarbonization in China compared to wind-solar-dominated strategies. By 2060, annualized costs drop by 218 billion CNY, marginal abatement cost falls from 3160 to 1401 CNY/t, and critical-metal-intensive electrolyzer and storage needs decline by 46.5% and 63.7%. Advocates regionally tailored transitions.

📄 Abstract（原文）
Abstract Wind and solar power are widely regarded as the primary energy sources for chemical decarbonization, yet their spatial mismatch with production hubs poses inherent challenges. Locally available hydropower, nuclear power, and biomass offer promising alternatives. Using a spatially explicit model with endogenous optimization of industrial spatial configuration, we show that diversified energy supply safeguards cost-effective and risk-mitigated chemical decarbonization in China, compared to the prevailing wind–solar-dominated strategies. By 2060, the annualized cost of chemical sector is reduced by 218 billion CNY (0.22% of China’s 2020 GDP), and the marginal abatement cost declines from 3160 to 1401 CNY/t, making net-zero emissions more economically feasible. Deployment requirements for critical-metal-intensive electrolyzers and energy storage technologies decline by 46.5% and 63.7%, respectively, and the still-immature direct air capture with utilization becomes largely unnecessary. Moreover, the potential stranded coal-based chemical capacity declines from 16.9 GW to 1.55 GW, and the chemical-sector contractions in Henan, Guizhou, and Chongqing are avoided, primarily through biomass-based methanol expansion. We caution against overly optimistic wind–solar-dominated strategies and advocate regionally tailored transitions.
