Description

    CROSS-REFERENCE TO RELATED APPLICATION
  • This application claims priority from Korean Patent Application No. 10-2019-0058695, filed on May 20, 2019, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.
    • BACKGROUND OF THE INVENTION 1. Field of the invention
  • The present invention relates to a mobile gaseous and liquid hydrogen refueling apparatus using a road in a hydrogen filling mode.
    • 2. Description of the Related Art
  • As is generally known, hydrogen is an element that is the lightest and the most abundant among elements on earth. Specifically, hydrogen occupies 75% of the mass of the universe. Hydrogen is a resource that is capable of being obtained simply by electrolyzing water and is very environmentally friendly since hydrogen emits no pollutants.
  • In addition, hydrogen has advantages in that hydrogen has very high energy efficiency, and therefore energy efficiency per unit weight of hydrogen is the highest among all resources including competing resources, such as gasoline, diesel, propane, methane, and ethanol.
  • Hydrogen has high energy efficiency, as described above. Due to recent development of technology, therefore, hydrogen is produced at a production plant in the form of production raw materials (e.g. petroleum, coal, natural gas, liquefied petroleum gas (LPG), biofuel, and nuclear energy) and is transported to a point of use (e.g. a filling station, a building, a power plant, and a general house) in a gaseous state or in a liquid state.
  • Here, gaseous hydrogen has lower energy density per unit weight than liquid hydrogen (liquid hydrogen: 22 MJ/kg, gaseous hydrogen: 4.8 MJ/kg) and lower energy density per unit volume than liquid hydrogen (liquid hydrogen: 7.8 MJ/L (liter), gaseous hydrogen: 2.5 MJ/L (liter)). For these reasons, energy activation is limited in the case in which hydrogen is transported in a gaseous state.
  • Meanwhile, in a conventional hydrogen filling mode, hydrogen in a gaseous state (hereinafter referred to as “gaseous hydrogen”) is compressed to high pressure by a compressor before being supplied to a point of use. As a result, temperature of the gaseous hydrogen increases due to normal temperature expansion thereof when the gaseous hydrogen is injected into a fuel tank. For this reason, a cooler capable of cooling the gaseous hydrogen to −40° C. is inevitably required.
  • The compressor and the cooler have high power consumption, and form a complicated structure together with structural components therearound. In addition, hydrogen in a liquid state (hereinafter referred to as “liquid hydrogen”) needs a compressor capable of compressing the liquid hydrogen to high pressure together with an evaporator capable of converting the liquid hydrogen into a gaseous state before being supplied to a point of use.
  • In the aspect of use of the liquid hydrogen, however, the compressor is connected to the evaporator such that the liquid hydrogen is expanded and then compressed. As a result, components of the compressor and the evaporator easily corrode and suffer from a severe change in pressure, whereby the lifespan of the components is shortened. In addition, stability of the compressor and the evaporator is reduced due to high pressure, and therefore merits in use of the liquid hydrogen are deteriorated.
  • A mode of filling the gaseous hydrogen is similarly disclosed in Korean Patent Application Publication No. 10-2017-0066587 entitled HYDROGEN STATION as a conventional art. A mode of filling the liquid hydrogen is similarly disclosed in Korean Patent Application Publication No. 10-2019-0031386 entitled HYDROGEN FILLING APPARATUS as a conventional art.
