English
This study presents an integrated techno-enviroeconomic and life-cycle assessment of a solar-green hydrogen hybrid system co-located with a textile mill in Pakistan. By incorporating an industrial wastewater reuse loop for hydrogen production and fuel cell condensate recovery, the system reduces the levelized cost of electricity from $0.10/kWh to $0.0866/kWh and avoids over 157,000 metric tons of CO2-equivalent emissions over 25 years. It offers a replicable pathway for circular water-energy integration and industrial decarbonization in semi-arid regions.

日本のGX文脈において
日本でも水素サプライチェーン構築や工場廃水再利用の重要性が高まる中、本論文は技術経済・環境評価の統合フレームワークを提示。日本の産業脱炭素化や水素利用戦略において、廃水処理コスト削減と水素製造の同時達成を示唆する参考事例となる。
In the global GX context
This paper provides a comprehensive framework for integrating water treatment with green hydrogen production, addressing both decarbonization and water scarcity. Globally, as industries face pressure to reduce freshwater use and carbon emissions, this study offers a data-driven, site-specific model for circular water-energy systems that can be adapted to other semi-arid, resource-constrained regions.

📄 Abstract（原文）
The dual pressures of climate change and industrial water scarcity demand integrated solutions that jointly decarbonize power supply and reduce freshwater dependency. This study presents a site-specific, techno-enviroeconomic and life-cycle evaluation of a closed-loop Solar–Green Hydrogen Hybrid System (SGHHS) co-located with Gul Ahmed Textiles in Karachi, Pakistan, integrating 22.75 MW solar PV, a 2.25 MW PEM electrolyser, 450 kg hydrogen storage, and a 1 MW PEM fuel cell to deliver dispatchable, round-the-clock clean electricity under reduced nighttime demand. Unlike most SGHHS studies that assume freshwater inputs and decouple water treatment from system economics, this work quantifies an integrated wastewater-to-ultrapure-water loop (MBR→RO→DI) with fuel-cell condensate recovery within a unified TEA–LCA framework. A novel configuration treats 4,050 L/day of textile effluent to produce PEM-compatible ultrapure water while recovering and recirculating clean water for reuse within the facility, leveraging a broader on-site effluent availability of ~ 400,000 L/day. Over a 25-year project horizon, the integrated water loop reduces the Levelized Cost of Electricity (LCOE) from USD 0.10/kWh to USD 0.0866/kWh through avoided freshwater procurement and effluent-management costs. Life-cycle assessment indicates the potential to avoid over 157,000 metric tons of CO₂-equivalent emissions. The proposed framework supports multiple Sustainable Development Goals (SDGs) and provides a replicable, data-driven pathway for circular water–energy integration and industrial decarbonization in semi-arid, resource-constrained regions.
