Since H2 has gradually drawn increasing attention in various sectors such as industry, transport, etc, how to produce and distribute them economically and safely is an eminent issue. This study addresses design of Optimal H2 supply Network Model which considers facility location problem. The proposed H2 supply network model allows us to determine where and how much produced H2 to be stored at apt local storages, where to build and transport, and where and how to share physical form of H2 on the purpose of maximizing the total net profit of handling a given demand of H2. Especially, this study addresses not only changeable demand with respect to two H2 physical forms compressed gas, liquid- on each region, though total H2 demand on each region is fixed, but changeable inventory together with two H2 physical forms, not previously addressed in the literature in spite of important issue. We also address the impact of demand’s fraction served from production facilities according to local selling price of H2. The applicability of the proposed model will be demonstrated by a case study of Korean H2 supply network with some remarks. The gained results aid determining policy to plan in the budget of supplying H2. |
