摘要

提出了一种用于交通枢纽的新型氢电复合能源系统。建立了可再生能源生产、储存、传输、利用全过程仿真模型，能够有效协调可再生能源与电力、制冷、供暖、氢能等动态需求。系统可以充分利用可再生能源，利用剩余的可再生能源生产LH2。为了提高传输容量，降低传输损耗，引入了超导氢电多能管道。经济分析表明，以6%的贴现率计算，该系统在17年后将实现盈利。环境评价表明，在可再生能源充足的情况下，氢能-电力多能系统的CO2排放量仅为常规系统的5%。该研究显示了氢能-电力多能系统的巨大潜力，为未来交通枢纽和其他高密度电力部门充分利用可再生能源和冷热负荷提供了方向。

Superconducting hydrogen-electricity multi-energy system for transportation hubs: Modeling, technical study and economic-environmental assessment

This article presents a novel hydrogen-electricity multi-energy system for transportation hubs. A new model has been established to simulate the entire process of renewable energy production, storage, transmission, to utilization, which can efficiently coordinate renewable energy and dynamic demands for electricity, cooling, heating and hydrogen energy. The system can fully utilize renewable energy, produce LH₂ by surplus renewable energy. Superconducting hydrogen-electricity multi-energy pipeline is introduced to increase the transmission capacity and reduce transmission loss. Economic analysis shows that with a discount rate of 6 %, the system would be profitable after 17 years. Environmental assessment shows that the CO₂ emission of the hydrogen-electricity multi-energy system can be only 5 % of that of the conventional system if the renewable energy is sufficient. This study shows great potential of using hydrogen-electricity multi-energy system, offering directions of fully utilizing renewable energy and cooling/heating loads for future transportation hubs and other high-dense power sectors.

期刊介绍： Applied Energy serves as a platform for sharing innovations, research, development, and demonstrations in energy conversion, conservation, and sustainable energy systems. The journal covers topics such as optimal energy resource use, environmental pollutant mitigation, and energy process analysis. It welcomes original papers, review articles, technical notes, and letters to the editor. Authors are encouraged to submit manuscripts that bridge the gap between research, development, and implementation. The journal addresses a wide spectrum of topics, including fossil and renewable energy technologies, energy economics, and environmental impacts. Applied Energy also explores modeling and forecasting, conservation strategies, and the social and economic implications of energy policies, including climate change mitigation. It is complemented by the open-access journal Advances in Applied Energy.
