Multi-site and multi-period optimization model for strategic planning of a renewable hydrogen energy network from biomass waste and energy crops

This study proposes an optimization-based approach for strategically planning a biomass-based hydrogen energy network. In achieving this goal, the superstructure of a biomass-based hydrogen energy system is proposed, which includes different biomass resources (biomass waste and energy crops) and various technologies (production, storage and terminal, refueling station, and transportation). A multi-site and multi-period optimization model is then developed using a mixed integer linear programming to determine the optimal investment timing and regional allocation alongside the selection of proper biomass types and technology combinations. The capability of the proposed approach is validated through a case study of Jeju Island, Korea. As a result, it was identified that the optimal network configuration as well as the investment and operation strategies are determined by the biomass type and regional biomass availability. In addition, the sustainability of the proposed energy system was analyzed using the criteria such as energy security and environmental protection, as well as economics. (C) 2019 Elsevier Ltd.
