Description

TECHNICAL FIELD

[0002] As a clean and efficient energy form, hydrogen energy is gradually becoming an important part of future energy systems. The development and utilization of hydrogen energy not only helps to reduce greenhouse gas emissions, but also promotes the diversification and sustainable development of energy structure. However, the widespread application of hydrogen energy faces a key problem: how to efficiently and safely produce and store hydrogen.

[0003] Traditional hydrogen production mainly relies on the reforming process of fossil fuels, which not only has high energy consumption, but also produces a large amount of carbon dioxide emissions. In recent years, water electrolysis hydrogen production technology has attracted much attention due to its abundant raw materials, pure products, and environmental friendliness. Water electrolysis hydrogen production through electrolytic cell electrolysis of water into hydrogen and oxygen is an ideal green hydrogen production method. However, the hydrogen produced by electrolytic cell often contains certain impurities such as water and oxygen, so it needs to be separated and purified to meet the requirements of subsequent applications.

[0004] In terms of hydrogen storage, although the traditional high-pressure gaseous storage method is mature, it has problems such as low storage density and high safety risks. In order to improve the storage density and safety, liquid hydrogen storage and solid hydrogen storage technology have emerged. Liquid hydrogen storage requires cooling hydrogen to extremely low temperature, which is technically complex and energy-consuming; solid hydrogen storage uses hydrogen storage materials to adsorb hydrogen, although the storage density is high, but the cost and regeneration performance of hydrogen storage materials are still the key factors restricting their application. Therefore, it is particularly important to develop an efficient, safe and economical hydrogen production and storage integrated equipment.

However, there are still some problems in the storage and transportation of hydrogen. For example, how to realize online filling and quick replacement of hydrogen storage cylinder, and how to ensure the safety and stability of hydrogen storage process, etc., these problems limit the further promotion and application of hydrogen production and storage technology.
