本研究はメキシコのテキーラ工場における2.5MWthのパラボリックトラフ太陽熱集熱システムを評価。最適設計（ソーラーマルチプル1.258）で年間太陽熱比率32%、CO2削減33.5%、熱平準化コストが重油比16.3%削減。エクセルギー効率23-28%は単独ボイラーの約4倍。メキシコの加速償却制度が経済性を大幅に改善することを示した。日射量の多い工業地域での太陽熱プロセス熱導入の再現可能な枠組みを提供。
English
This study evaluates a 2.5 MWth parabolic trough solar collector system for industrial process heat in a tequila factory in Mexico. The optimal design achieves a 32% solar fraction, 33.5% CO2 reduction, and a levelized cost of heat 16.3% below the fuel-oil baseline. Exergy efficiency is 23-28%, four times that of a stand-alone boiler. Mexico's accelerated depreciation policy significantly improves economic feasibility. The framework is replicable for sun-rich industrial regions.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
この論文は日射量の多い地域での太陽熱工業プロセス利用の可能性を示すが、日本の日射条件や工業熱需要とは異なる。しかし、技術経済評価の枠組みは日本の食品・化学産業など中温熱需要分野に応用可能であり、加速償却制度の効果は日本の補助金設計に示唆を与える。
In the global GX context
This study provides a detailed techno-economic assessment of solar process heat in an emerging economy, demonstrating significant CO2 reduction and economic viability under policy support. The findings are relevant for global industrial decarbonization, especially in gas-constrained sun-rich regions. The exergy analysis adds depth to performance evaluation.

📄 Abstract（原文）
The industrial sector accounts for 34% of global energy consumption, with heat representing 74%, predominantly derived from fossil fuels. Solar Heat for Industrial Processes (SHIP) offers a viable decarbonisation route for low-to-medium temperature applications (80–250∘C)—a range that includes processes such as tequila production. Yet integrated techno-exergo-economic assessments for small-scale, modular systems in agro-industrial contexts remain scarce. This study presents a technical, thermodynamic, and economic evaluation of a 2.5 MWth parabolic trough collector system with thermocline thermal energy storage, integrated into a tequila production facility in Jalisco, México. A parametric analysis across seven solar multiple configurations identifies SM = 1.258 as the economic optimum, yielding an annual solar fraction of 32.0%, a CO2 reduction of 33.5%, a levelised cost of heat of 75.19 USD/MWhth (16.3% below the fuel-oil baseline), and a payback period of 13.39 years under full accelerated depreciation. The system’s exergy efficiency (23–28%) is nearly four times that of the stand-alone boiler (6.31%); the analysis further quantifies diminishing returns beyond SM ≈ 1.4 and demonstrates that México’s accelerated depreciation provision substantially broadens the economically feasible design space. These findings provide a replicable techno-exergo-economic framework for SHIP integration in gas-constrained, high-irradiation industrial regions, supporting decarbonisation efforts in emerging economies.
