Abstract

A hydrogen supply system is configured to supply hydrogen to a fuel-cell vehicle by using a receptacle for hydrogen transport, and includes: a filling unit provided at a hydrogen filling facility and configured to fill the receptacle with hydrogen; a management unit configured to calculate a transport timing at which the hydrogen-filled receptacle is transported to a business facility that operates the fuel-cell vehicle; a transport unit configured to transport the hydrogen-filled receptacle to the business facility in accordance with the transport timing; and a disposition unit configured to dispose the hydrogen-filled receptacle transported to the business facility at a place to which the fuel-cell vehicle is capable of accessing to have a refill of the hydrogen in the business facility.

First claim

The invention claimed is:

1. A hydrogen supply system configured to supply hydrogen to a fuel-cell vehicle by using a receptacle for hydrogen transport, the hydrogen supply system comprising:
a filling dispenser provided at a hydrogen filling facility and configured to fill the receptacle with hydrogen;
a processor configured to calculate a transport timing at which the hydrogen-filled receptacle is transported to a business facility that operates the fuel-cell vehicle;
a transport vehicle configured to transport the hydrogen-filled receptacle to the business facility in accordance with the transport timing; and
a disposition vehicle configured to dispose the hydrogen-filled receptacle transported to the business facility at a place to which the fuel-cell vehicle is capable of accessing to have a refill of the hydrogen in the business facility,
wherein the processor is further configured to:
acquire hydrogen remaining amount data on the receptacle disposed at the business facility,
acquire hydrogen remaining amount data on the fuel-cell vehicle operated at the business facility,
predict a remaining amount of the hydrogen that is able to be used at the business facility in the future based on the hydrogen remaining amount data on the receptacle, the hydrogen remaining amount data on the fuel-cell vehicle, a correction ratio of a hydrogen remaining amount of the receptacle, a correction ratio of a hydrogen remaining amount of the fuel-cell vehicle and a consumed hydrogen amount of the fuel-cell vehicle per unit time, and
calculate the transport timing based on the predicted remaining amount of the hydrogen.

2. The hydrogen supply system according to claim 1 , wherein the receptacle includes a dispenser configured to supply the hydrogen to the fuel-cell vehicle.

3. The hydrogen supply system according to claim 1 , wherein
the transport vehicle is configured to
collect the receptacle disposed in the business facility and having a decreased hydrogen storage amount, and
transport the receptacle to the hydrogen filling facility, and

the filling dispenser is configured to fill the receptacle transported to the hydrogen filling facility with the hydrogen.

4. The hydrogen supply system according to claim 3 , wherein, when collecting the receptacle having a decreased hydrogen storage amount, the transport vehicle is configured to transport another hydrogen-filled receptacle to the business facility.

5. The hydrogen supply system according to claim 1 , wherein
the receptacle includes a plurality of hydrogen storage containers, and
each of the hydrogen storage containers is a composite structure container made of a steel liner and a carbon-fiber-reinforced plastic.

6. The hydrogen supply system according to claim 5 , wherein the carbon-fiber-reinforced plastic used for each of the hydrogen storage containers has a longitudinal elastic modulus equal to or larger than 230 GPa.

7. The hydrogen supply system according to claim 5 , wherein each of the hydrogen storage containers has a maximum hydrogen storage pressure of 40 MPa or higher.
