Problems solved by technology

Therefore, there is a problem that a compressor is required and the compression cost of the hydrogen supply is large
In addition, in order to store compressed high-pressure hydrogen, a container capable of withstanding high pressure is required, resulting in high storage costs.

no. 1 Embodiment approach

[0018] A1. System structure:

[0019] figure 1 It is an explanatory diagram showing a schematic configuration of a hydrogen compression system 10 as an embodiment of the present invention. The hydrogen gas compression system 10 uses water pressure in the sea to compress hydrogen gas, and stores the compressed hydrogen gas. The hydrogen compression system 10 includes a transfer unit 100 , a gas release unit 150 , a storage unit 200 , and a recovery unit 300 .

[0020] The transfer unit 100 guides the hydrogen storage container 110 filled with hydrogen gas to the hydrogen storage chamber 210 included in the storage unit 200 .

[0021] figure 2 It is an external view showing the structure of the hydrogen storage container 110 . The hydrogen storage container 110 includes a main body portion 111 , an attachment portion 112 , and a weight portion 113 . The main body portion 111 has a substantially spherical appearance shape, and a hydrogen storage portion 111 a is formed insi...

no. 2 Embodiment approach

[0035] Figure 4 It is an explanatory diagram showing a schematic configuration of a hydrogen compression system 10a in the second embodiment. The hydrogen compression system 10a according to the second embodiment has a transfer recovery unit 400 instead of the transfer unit 100 and the recovery unit 300, and figure 1 The hydrogen compression system 10 of the first embodiment shown is different. The other configurations of the hydrogen compression system 10 a of the second embodiment are the same as those of the hydrogen compression system 10 of the first embodiment, and therefore the same components are assigned the same reference numerals and detailed descriptions thereof are omitted.

[0036] The transfer and recovery unit 400 is a functional unit obtained by combining the transfer unit 100 and the recovery unit 300 in the first embodiment. That is, the transfer recovery unit 400 guides the hydrogen storage container 110 filled with hydrogen gas to the hydrogen storage ch...

Embodiment approach 1

[0042] In each embodiment, the main body 111 of the hydrogen storage container 110 is formed of aluminum, but it is not limited to aluminum, and may be formed of other arbitrary types of metals. In addition, the main body portion 111 may be formed of resin for the purpose of improving corrosion resistance. In this structure, by forming the main body 111 to have a structure that deforms under a water pressure environment lower than about 70.9 MPa and does not crack even under this water pressure environment, The same effects as those of the respective embodiments are achieved. As the main body portion 111 of such a hydrogen storage container 110 , for example, a resin liner used in a hydrogen storage fuel tank may be used.

Abstract

A hydrogen compression system and a hydrogen compression method of the present invention suppress costs required for hydrogen compression and storage. The hydrogen compression system comprises a hydrogen storage chamber placed at a predetermined water depth in water to communicate with surrounding water; a hydrogen container filled with hydrogen gas by a lower pressure than a hydraulic pressure atthe predetermined water depth; a transporting portion configured to guide the hydrogen container that is filled with the hydrogen gas, from above the predetermined water depth to the hydrogen storagechamber; a gas release portion configured to cause the hydrogen gas to be released from the hydrogen container transported to the hydrogen storage chamber and to be stored in the hydrogen storage chamber; a hydrogen recovery device placed above the predetermined depth; and a tube arranged to connect inside of the hydrogen storage chamber with the hydrogen recovery device.

Description

technical field [0001] This invention relates to the compression and storage of hydrogen. Background technique [0002] Hydrogen is increasingly in demand as a fuel for power generation by fuel cells or as a raw material for industrial use. Hydrogen gas produced by hydrogen production equipment or the like may be compressed in a hydrogen production equipment or a hydrogen station, stored in a container, and supplied to a fuel consumption device such as a fuel cell vehicle through a distributor. Patent Document 1 discloses a configuration in which hydrogen gas produced by a gas production device is compressed in a compressor, temporarily stored in an accumulator, and then filled into a vehicle via a distributor. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2017-131862 [0004] As in Patent Document 1, when hydrogen gas is generally stored, the hydrogen gas is compressed to, for example, a high-pressure gas of 70 MPa (megapascals) in order to store a large amoun...
