Embodiment Construction

[0020] The present invention will be further described below through specific embodiments, but the present invention is not limited to these specific embodiments.

[0021] The hybrid hydrogen storage system of the present invention uses hydrogen as a heat medium, and includes a high-pressure gaseous hydrogen storage unit, a solid-state hydrogen storage unit, a heat exchange unit, and a gas circulation pipeline; wherein, the solid-state hydrogen storage unit is arranged inside the high-pressure gaseous hydrogen storage unit, and the hydrogen It can freely flow between the two; the gas circulation pipeline passes through the heat exchange unit, the solid hydrogen storage unit in the high-pressure gaseous hydrogen storage unit, the heat exchange unit in turn from the hydrogen source, and finally connects to the hydrogen inlet of the high-pressure gaseous hydrogen storage unit. Among them, the high-pressure gaseous hydrogen storage unit adopts a hydrogen storage container with a me...

Abstract

The invention discloses a mixed hydrogen storage system using hydrogen as a heat medium, which comprises a high-pressure gas hydrogen storage unit, a solid hydrogen storage unit, heat exchange units and a gas circulation pipeline, wherein the solid hydrogen storage unit is arranged inside the high-pressure gas hydrogen storage unit, and hydrogen can freely flow between the solid hydrogen storage and high-pressure gas hydrogen storage; and the gas circulation pipeline is connected between a hydrogen source and a hydrogen inlet of the high-pressure gas hydrogen storage unit sequentially through the heat exchange unit, solid hydrogen storage unit and heat exchange unit. The mixed hydrogen storage system uses the hydrogen in the system as the heat medium instead of water in the traditional mode, and greatly improves the condition of irreversible breaking of the solid hydrogen storage bed due to possible rupture when the heat exchange water pipe is under superhigh-pressure hydrogen storage conditions, thereby enhancing the system safety.

Description

technical field [0001] The invention relates to a hybrid hydrogen storage system using hydrogen as a heat medium, belonging to the technical field of hybrid hydrogen storage. Background technique [0002] At present, the increasingly severe energy crisis and environmental pollution have made the development of clean and renewable energy an important issue for various countries. Hydrogen energy has become the energy carrier with the most development potential in the future due to its renewability and good environmental protection effect. At present, many countries have begun to study new energy vehicles powered by hydrogen energy, and have made great progress. With the gradual promotion of new energy vehicles powered by hydrogen, the construction of hydrogen refueling stations is imperative. [0003] At present, the increasingly mature hydrogen storage methods mainly include high-pressure gaseous hydrogen storage, liquid hydrogen storage, and solid-state hydrogen storage. ...
