- Summary:
- In order to give full play to the economic and environ mental advantages of liquid organic hydrogen carrier(LOHC) technology in hydrogen storage and transportation as well as its technological advantages as a hydrogen source for hydrogen refueling station(HRS) supply, it promotes the change of hydrogen supply method in HRSs and facilitates its technological landing in the terminal of HRSs. In this paper, combining the current commercialization status of organic liquid tech nology and the current construction status of HRS in China, we establish a traditional long-tube trailer HRS model through Matlab Simulink, carry out modification on the existing process, maximize the use of the original equipment, and introduce the hydrogen production end of the station with organic liquid as an auxiliary hydrogen source. Research and design of the two hydrogen sources of gas extraction strategy and the station control strategy and the formation of Stateflow language model, to realize the verification of the LOHC technology auxiliary hydrogen supply program. Different LOHC hydrogen production quantities are set to analyze their
effects on the cost of hydrogen supply, energy consump tion, and high-pressure hydrogen inventory (safety) in the HRS. The results show that in the case of LOHC for auxiliary hydrogen supply, a specific amount of hydrogen production can ensure the full utilization of the trailer
at the station and avoid overnight stationing. In terms of hydrogen supply costs, LOHC for auxiliary hydrogen supply is cost-effective, with overall transportation costs decreasing by 25.9%-56.1% as the amount of LOHC production increases.
