A hydrogen refueling station using renewable energy

Abstract

The invention provides a self-supporting hydrogen refueling station utilizing renewable energy sources. The self-supporting hydrogen refueling station comprises a renewable energy source generation device, an electric energy switching-in / rectifying / power distribution subsystem, a reversible fuel cell system, a water storage tank, a hydrogen storage system and a hydrogen refueling machine. The hydrogen refueling station comprises a first operation mode with the renewable energy sources and a second operation mode without the renewable energy sources. According to the self-supporting hydrogen refueling station utilizing the renewable energy sources, producing and preparing of hydrogen and operating of the hydrogen refueling station are combined with the dynamic characteristic of the renewable energy sources, and thus, normal operating and hydrogen refueling when no renewable energy source is fed can be maintained.

Description

technical field [0001] The invention relates to a hydrogen refueling station for hydrogen energy vehicles, in particular to a self-supporting hydrogen refueling station with hydrogen production and storage capacity. Background technique [0002] In the prior art hydrogen refueling station and hydrogen refueling station design, the source of hydrogen is mainly produced through high-carbon emission chemical processes such as natural gas reforming; the transportation of hydrogen mainly relies on long-distance high-pressure hydrogen transportation or liquid hydrogen transportation to the hydrogen refueling station to realize Services for hydrogen energy vehicles. The cost of hydrogen production and transportation is high and is accompanied by high carbon dioxide emissions and other pollutant emissions. With the popularity of hydrogen fuel cell vehicles, the network of hydrogen refueling stations needs to be similar to the distribution network of gas stations to increase the bat...
