| Hydrogen energy is regarded as one of the important fuels to reduce carbon emissions in long-distance road transportation,railroad,aviation and shipping,and therefore the development of hydrogen vehicles has greatly enriched the application mode of hydrogen energy in the transportation field.The planning of hydrogen refueling stations,as an important infrastructure to provide renewal energy service for hydrogen vehicles within the transportation system,is of great significance to the consumption of hydrogen energy in the transportation field.At present,the source of hydrogen energy is still mainly fossil energy and hard to achieve net zero emission under the whole life cycle.How to use wind,light and other clean energy to produce hydrogen energy,i.e.green hydrogen energy,is a key issue that needs to be solved nowadays.The rich distribution of natural endowment in the Middle and West China provide a tremendous prospect to develop the research on green hydrogen energy application.In order to promote the application of green hydrogen energy in transportation system,this paper proposes an integrated system for green hydrogen energy in production-storage-use field and constructs several models for the site planning of hydrogen production and hydrogen refueling sites in it.The main research work of this paper is as follows:(1)It proposes the basic concept of green hydrogen energy integrated system,that is.the transportation system uses the infrastructure such as service area,converts solar energy into hydrogen energy by building photovoltaic arrays and hydrogen production equipment,and delivers to hydrogen refueling stations to supply hydrogen energy to passing hydrogen energy to the passing hydrogen vehicles.The system integrates the production,storage,transportation and consumption of green hydrogen,providing a viable development approach for the integration of energy and transportation.(2)This paper,in the first place,reviews the current development status of hydrogen energy production,storage and transportation technology,hydrogen refueling stations.and hydrogen vehicles,and then,complies and analyzes the current research status of hydrogen refueling station site selection planning,in order to provide data support and theoretical basis for building the model of green hydrogen energy production-storage-use integrated system and green hydrogen refueling station siting planning.(3)For linear roads,after considering the system of hydrogen energy production.storage,transportation and investment in construction and operation,a model is constructed to optimize the location of hydrogen refueling station based on the lowest cost of green hydrogen energy system.The important highways in northwest China are selected as a typical example for model solution,and the optimal site selection plan of hydrogen refueling station along the road is given.(4)On the basis of the lowest cost model on the supply side,this paper puts forwards the lowest cost model of hydrogen on the user side and verifies its validity through a validation case.The newly proposed model uses a p-median model to characterize the distance cost of hydrogen for users and a gravity model to characterize the siting preferences of different alternative points.For the proposed multi-objective planning problem,a typical example is selected to solve the important highway network in western China.The TOPSIS analysis is performed on the solved optimal site selection solution set,the indicators affecting the site selection results in the actual site selection process are given,and the optimal site selection solution is evaluated and analyzed through the comprehensive scoring.The results of solving the algorithm show that the model has certain theoretical and practical significance. |
