Hydrogen gas supply system, point management system, and service management system

A hydrogen gas supply system that supplies hydrogen gas to a user, the hydrogen gas supply system comprising:

• a storage tank that stores hydrogen;
• a communication interface that receives at least either of burden information indicative of an environmental burden exerted during manufacturing of hydrogen externally received by the storage tank and quality information indicative of quality with respect to the hydrogen externally received by the storage tank;
• a control panel that provides a graph with respect to the hydrogen to be supplied from the storage tank to the user in accordance with the at least either of the burden information and the quality information;
• a hydrogen gas supply line that supplies the hydrogen in the storage tank to outside of the hydrogen gas supply system according to input received by the control panel;
• and
• a controller, wherein the controller prepares a first portion of the graph related to a first type of hydrogen based on (i) an amount of the first type of hydrogen received by the storage tank, the first type of hydrogen being obtained by reaction of fossil fuel and water, and (ii) the at least one of the burden information and the quality information related to the first type of hydrogen the burden information and the quality information related to the first type of hydrogen being received by the communication interface;
• and wherein the controller prepares a second portion of the graph related to a second type of hydrogen based on (i) an amount of the second type of hydrogen received by the storage tank, the second type of hydrogen being obtained by allowing water to undergo electrolysis with electric power obtained by utilizing natural energy, and (ii) the at least one of the burden information and the quality information related to the second type of hydrogen, the burden information and the quality information related to the second type of hydrogen being received by the communication interface,
• wherein the second portion of the graph is prepared in a different color from a color of the first portion and
• wherein the controller is adapted to receive an input from a user based on the first or second portion of the graph, and to dispense hydrogen according to the user input.
