MODELING OF FUELING INFRASTRUCTURE FOR CRYO-COMPRESSED HYDROGEN FOR HEAVY MACHINERY UNDER QUARRY CONDITIONS

Abstract

BACKGROUND: In the context of the growing demand for environmentally friendly and efficient energy sources, hydrogen has emerged as a carrier with a high energy density and, essentially, zero CO₂ emissions into the atmosphere. For the steadily developing sector of heavy mobility powered by hydrogen fuel, the issue of safe and high-density hydrogen storage is of significant importance.

AIMS: Theoretical analysis of the feasibility of applying rapid refueling technology with cryo-compressed hydrogen for quarry equipment.

MATERIALS AND METHODS: CFD modeling of heat influx to the changeable cartridge with cryo-compressed hydrogen has been conducted. The cycle of compressing gaseous hydrogen followed by cooling to 85K was simulated in the ASPEN HYSYS software environment

RESULTS: The specific costs of the cycle have been evaluated, and conclusions have been drawn regarding the energy efficiency of this storage method in relation to known and already tested methods of hydrogen fuel storage, including those used on board vehicles.

CONCLUSIONS: In the course of the current study, a conclusion was reached regarding the potential promising use of cryo-compressed refueling for quarry equipment utilizing interchangeable cartridge technology. Based on the simulation results, it can be concluded that this solution can be implemented and operated safely. Additionally, theoretical values of Specific Energy Consumption (SEC) for this technology have been obtained during the research.
