Within the context of multi-criteria decision-making, the Analytical Hierarchy Process was employed to evaluate four main criteria: energy production potential, energy consumption potential, renewable energy capacity, and industrial development combined with population density. The respective weights of these criteria were calculated as 55 %, 25 %, 6 %, and 14 %. Regional priorities were established, and statistical robustness was ensured through bootstrap analysis, yielding 95 % confidence intervals for regional scores and revealing significant differences among regions. The interconnections and relative contributions of cities were visualized using a Sankey diagram, providing a holistic view of supply-demand dynamics. Scenario-based cost–benefit and cost–performance analyses indicate that, under optimistic assumptions, the benefit/cost ratios reach 0.53 for the primary corridor, 0.64 for the secondary corridor, and 0.54 for the tertiary corridor. By replacing fossil-based hydrogen flows with green hydrogen, the proposed HPC has the potential to abate approximately 5 tCO₂ per tonne of hydrogen transported, contributing significantly to Europe's decarbonization efforts. Furthermore, the corridor is projected to generate annual revenues up to 1.8 billion € under optimistic scenarios, enhancing supply diversification and leveraging Türkiye's unique transcontinental position as a strategic energy bridge. These findings offer actionable insights for policymakers and investors, supporting the feasibility and scalability of large-scale hydrogen infrastructure planning in Türkiye and the broader region.</div></div>","PeriodicalId":337,"journal":{"name":"International Journal of Hydrogen Energy","volume":"152 ","pages":"Article 150208"},"PeriodicalIF":8.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144524149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental setup involved co-pyrolysis at temperatures between 550 °C and 600 °C using Ni/Al₂O₃ and La/Al₂O₃ as catalysts. Gas chromatography analysis revealed that Ni/Al₂O₃ catalyst produced syngas with a hydrogen concentration of 38.28 % and a total yield of 68 %, while La/Al₂O₃ resulted in 35.45 % hydrogen with a 65.2 % yield. The CI engine tests demonstrated improved brake thermal efficiency (BTE) in dual fuel mode, reaching 32.20 % with hydrogen-enriched syngas, compared to 30.98 % with syngas without hydrogen enrichment.

This study employed Aspen Plus V12.1 and MATLAB to develop rigorous system-level models of all subsystems involved in the sustainable urea production process. These subsystems include a cryogenic air separation unit (CASU), a modular system of alkaline electrolysers (AEL), a green Haber-Bosch (HB) process, an MEA-based CO₂ capture system, and the Stamicarbon process. To enhance the energy efficiency and cost-effectiveness of urea production, waste heat generated during green ammonia synthesis in the HB process was integrated into the stripper column of the MEA-based CO₂ capture system for solvent regeneration. A detailed economic analysis was conducted to assess the impact of this heat integration (HI) on reducing the CO₂ capture costs and, consequently, the overall urea production costs. Additionally, several heat supply scenarios were evaluated to meet the heat demand of the CO₂ stripper column in the Stamicarbon process. These included natural gas combustion, a cascade heat pump (HP), and natural gas combustion integrated with a cryogenic CO₂ capture (CCC) system. The results indicated that HI significantly decreases both the energy penalty and costs of the MEA-based CO₂ capture process, reducing the CO₂ capture costs by 41.27 % in 2024 and lowering the energy penalty by 50.40 %. Among the scenarios investigated, the cascade HP with HI proved to be the most cost-effective option for urea production. Additionally, electricity costs for operating the modular alkaline electrolyzers (AEL) dominate the sustainable urea production expenses, with 88.07 %–91.26 % of electricity costs allocated to AEL, depending on the selected production scenario.
