Description

technical field [0001] The present invention relates to the field of mechanical equipment, in particular to a specially designed gas supply equipment and a method for supplying gas using the equipment, in particular to a hydrogen refueling station and pressure compound hydrogenation using the hydrogen refueling station to perform hydrogen refueling in a specially designed manner method. Background technique [0002] For a long time, vehicles powered by fuel cells have attracted widespread attention due to their low pollution and high energy efficiency. of green energy. There have been many research reports on hydrogen fuel cell vehicles, some of which are being gradually put into commercialization. Many countries and regions, including the United States, Japan, China, South Korea, and the European Union, are vigorously developing hydrogen vehicles and actively building hydrogen refueling stations and related hydrogen energy infrastructure. Using hydrogen as power has beco...

Problems solved by technology

However, compared with conventional fossil fuel vehicles, a big disadvantage of hydrogen energy vehicles is that their hydrogenation equipment cannot meet the relevant requirements

[0003] For example, many hydrogen refueling stations are unable to adapt to changes in hydrogen refueling load during peak hours, regular hours, and late night hours when there is little demand for refueling

For example, in the case of continuous hydrogen refueling of vehicles during heavy load peak hours, it is easy to have insufficient hydrogen supply capacity. Significantly decreased, and the hydrogenation rate of subsequent vehicles was significantly slower

If a high-pressure large-scale hydrogen storage tank is configured according to the requirements of peak hours, and a high-pressure compressor is used to continuously provide and store a large amount of high-pressure hydrogen, there will be significant energy waste and machine loss during regular hours and late night hours, resulting in a substantial increase in infrastructure investment and maintenance costs do not match the supply of hydrogen, and may even render the associated equipment completely economically unviable
