Abstract
A control unit is configured to communicate with a terminal owned by a power company. When a hydrogen generation request is received from the terminal, the control unit determines whether hydrogen is to be generated based on a state of a hydrogen generation device, and transmits a determination result to the terminal. When a power sale request is received from the terminal, the control unit determines whether power is to be sold based on a state of the hydrogen generation device, and transmits a determination result to the terminal.
Claims9
A hydrogen station comprising:
- a hydrogen generation device including an electrolytic cell configured to electrolyze water to generate hydrogen, a hydrogen tank configured to store the hydrogen generated by the electrolytic cell, a fuel battery configured to generate electricity from the hydrogen in the hydrogen tank, a converter configured to convert electricity generated by the fuel battery into alternating current and to supply the alternating current to a power grid of a power company, a filler configured to fill an external hydrogen tank with the hydrogen stored in the hydrogen tank, and a flow meter configured to measure an amount of hydrogen being output from the filler;
- and
- a control unit comprising a microcomputer and configured to control the hydrogen generation device,
- wherein the control unit is configured to communicate with a terminal owned by the power company, the control unit being configured to:
- receive a value of the amount of hydrogen being output from the flow meter,
- determine whether the hydrogen is to be generated based on a state of the hydrogen generation device when a hydrogen generation request is received from the terminal,
- transmit, to the terminal, a determination result of whether the hydrogen is to be generated, and
- when a power supply request is received from the terminal:
- determine whether hydrogen is being output from the filler based on the value received from the flow meter,
- determine whether power is to be supplied to the power grid based on a determination result of whether the hydrogen is being output from the filler, and
- transmit, to the terminal, a determination result of whether the power is to be supplied to the power grid.
A control unit for a hydrogen station for controlling a hydrogen generation device, the hydrogen generation device including an electrolytic cell configured to electrolyze water to generate hydrogen, a hydrogen tank configured to store the hydrogen generated by the electrolytic cell, a fuel battery configured to generate electricity from the hydrogen in the hydrogen tank, a converter configured to convert electricity generated by the fuel battery into alternating current and to supply the alternating current to a power grid of a power company, a filler configured to fill an external hydrogen tank with the hydrogen stored in the hydrogen tank, and a flow meter configured to measure an amount of hydrogen being output from the filler,
- wherein the control unit comprises a microcomputer and is configured to communicate with a terminal owned by the power company,
- the control unit is configured to:
- receive a value of the amount of hydrogen being output from the flow meter,
- determine whether the hydrogen is to be generated based on a state of the hydrogen generation device when a hydrogen generation request is received from the terminal, and
- transmit, to the terminal, a determination result of whether the hydrogen is to be generated;
- and
- when a power supply request is received from the terminal:
- determine whether hydrogen is being output from the filler based on the value received from the flow meter,
- determine whether power is to be supplied to the power grid based on a determination result of whether the hydrogen is being output from the filler, and
- transmit, to the terminal, a determination result of whether the power is to be supplied to the power grid.
A non-transitory tangible computer readable storage medium that stores a computer program for a hydrogen station for controlling a hydrogen generation device, the hydrogen generation device including an electrolytic cell configured to electrolyze water to generate hydrogen, a hydrogen tank configured to store the hydrogen generated by the electrolytic cell, a fuel battery configured to generate electricity from the hydrogen in the hydrogen tank, a converter configured to convert electricity generated by the fuel battery into alternating current and to supply the alternating current to a power grid of a power company, a filler configured to fill an external hydrogen tank with the hydrogen stored in the hydrogen tank, and a flow meter configured to measure an amount of hydrogen being output from the filler, the computer program, when executed by a processor, causing a computer to perform a process including:
- receive a value of the amount of hydrogen being output from the flow meter,
- determining whether the hydrogen is to be generated based on a state of the hydrogen generation device when a hydrogen generation request is received from a terminal owned by the power company,
- transmitting, to the terminal, a determination result of whether the hydrogen is to be generated based on the state of the hydrogen generation device,
- when a power supply request is received from the terminal:
- determining whether hydrogen is being output from the filler based on the value received from the flow meter,
- determining whether power is to be supplied to the power grid based on a determination result of whether the hydrogen is being output from the filler, and
- transmitting, to the terminal, a determination result of whether the power is to be supplied to the power grid.
