(149c) Strategic Optimization of Hydrogen Supply Chain Networks for Economic and Environmental Performance – Qatar Case Study

This study presents a multi-period integrated optimization model for designing a strategic hydrogen supply chain (HSC) network, focusing on the post-production stages: conditioning, storage, transportation, and reconditioning. Using Qatar as a case study, the model evaluates three HSC pathways—ammonia, liquid, and compressed hydrogen—across pre-conditioning, storage, shipping, and post-conditioning stages. The optimization covers a 20-year planning horizon, supporting long-term strategic planning for hydrogen export infrastructure. The model integrates economic and environmental considerations to analyze HSC performance across various scenarios, incorporating realistic constraints such as investment ceilings and emission caps. Key findings reveal the trade-offs between different hydrogen pathways and design strategies in terms of cost and environmental impact. The ammonia pathway dominates when no emission penalties are imposed but becomes less competitive as emission penalties increase, driving a shift towards the liquid hydrogen pathway. In scenarios with strict emission limits, short-distance and mid-range markets were prioritized, emphasizing the importance of emissions-conscious strategies. This study highlights the value of optimization tools in balancing economic and environmental objectives, providing policymakers and industry stakeholders with a robust framework for designing sustainable and efficient HSC networks.
