In the evolving landscape of sustainable energy, efficient management of the hydrogen supply chain is paramount. This study addressed the critical need for decision-making support in this sector, highlighting the development and potential impact of a comprehensive hydrogen supply chain decision database. Utilizing a combination of qualitative and quantitative research methods, the study involved the collection and analysis of data across various stages of the hydrogen supply chain. Emphasis was placed on identifying key decision-making factors, integrating diverse data sources, and employing advanced analytical techniques to enhance the database’s utility. The findings revealed significant insights into the hydrogen supply chain, including bottlenecks, efficiency parameters, and potential areas for optimization. The developed database demonstrated its capability to aid in strategic decision making, offering a tool for stakeholders to navigate the complexities of hydrogen supply and distribution. The creation of the hydrogen supply chain decision database marks a step forward in the field, providing a valuable resource for researchers, policymakers, and industry professionals. It underscores the necessity of data-driven approaches in optimizing the hydrogen supply chain, potentially contributing to the acceleration of sustainable energy initiatives.

This paper studies a multicommodity logistic network. The decisions at the strategic level are supposed to be already taken, so the number and the location of the different sites, the products to be manufactured or stored on each site, the volumes of the flows exchanged between sites and the transportation modes to use are known. Then, our purpose is to improve the global cost of the network by aggregating the orders. In this article we consider an initial solution which specifies for each order the origin and the destination points, the delivery frequency and the quantities to be delivered on each shipment. Then we propose a descent algorithm for generation and evaluation of new solutions by transport consolidations
