Description

Mobile hydrogen charging station The present invention relates to a mobile hydrogen refueling station, and more specifically, to a mobile hydrogen refueling station equipped with solar panels to produce hydrogen based on solar energy and refuel external vehicles. Hydrogen energy is an energy source that stores and uses energy in the form of hydrogen, and is one of the ultimate clean energy sources of the future that replaces oil and coal. Hydrogen, which serves as the raw material for this energy, is so abundant that it accounts for 75% of the mass of the universe. In its natural state, hydrogen exists infinitely in a form combined with oxygen and carbon. Furthermore, hydrogen is environmentally friendly because it does not produce pollutants such as fine dust when generating energy, and emits only pure water as a byproduct. In addition, hydrogen complements this by storing surplus electricity from renewable energy cheaply and efficiently. Accordingly, it can enable energy transition in industrial and transportation sectors that require a stable energy supply. Due to these characteristics, hydrogen is considered a leading clean energy source to replace fossil fuels. In other words, as the most abundant and lightest element in the universe, hydrogen is gaining attention as a clean energy source because it can be converted into water and returns to water after use. Such hydrogen energy can be obtained by decomposing it through water electrolysis, and various methods for generating and utilizing hydrogen energy are currently being researched. In road traffic, in addition to traditional vehicles driven by internal combustion engines, particularly automobiles, vehicles equipped with electric or auxiliary drive systems are also being used increasingly frequently. For example, high-performance batteries or fuel cells are used to supply electrical energy to the drive system. In addition, there are vehicles powered by hydrogen engines or natural gas combustion engines. Appropriate infrastructure must be provided for charging batteries or filling the vehicles' fuel tanks and storage containers. In this regard, hydrogen energy can be recharged by users visiting hydrogen refueling stations located in various places, and these stations can store hydrogen energy supplied from an external source or produce and store hydrogen on-site, supplying it to vehicles when needed. External power supply is essential for the operation of such hydrogen refueling stations, and methods to secure this power are being researched. In addition, methods to operate hydrogen refueling stations more efficiently by utilizing a mobile system rather than operating them at a fixed location are also being studied.
