Abstract

Most planning of the traditional hydrogen energy supply chain (HSC) focuses on the storage and transportation links between production and consumption ends. It ignores the energy flows and interactions between each link, making it unsuitable for energy system planning analysis. Therefore, we propose the concept of a hydrogen energy chain (HEC) based on the HSC, which emphasizes the interactions between different types of energy flows in the production, compression, storage, transportation, and application links of hydrogen. The HEC plays a crucial role in mitigating fluctuations of renewable energy and facilitating the optimal allocation of heterogeneous energy sources across time and space. Effective collaborative planning models that consider HEC are essential for the optimal configuration of multi-energy systems (MESs), which guarantees high-efficiency operation and the economic and environmental friendliness of the system. This paper presents a systematic review of recent articles on collaborative planning of integrated hydrogen energy chain multi-energy systems (HEC-MESs). First, we introduce the basic framework of HEC-MES, focusing on the current research status of the production, compression, storage, transportation, and application links in HEC. Furthermore, we review technology types of hydrogen energy for planning and summarize the typical forms of HEC in MESs. Then, the following sections outline the models and methods for collaborative planning of HEC-MES. They include detailed analyses of covered sector types, spatial and temporal scopes of planning, uncertainties, model formulations, and solution methods. Finally, the paper concludes by summarizing the research gaps identified in current articles and outlining directions for future research.
