What is the traditional hydrogen production technology?

On the earth where human beings live, although hydrogen is the most abundant element, there is very little natural hydrogen, so hydrogen-containing substances can only be obtained by treatment. Hydrogen energy is a kind of secondary energy. To develop and utilize this ideal clean energy, we must first develop hydrogen sources, that is, research and develop various hydrogen production methods. Hydrogen energy belongs to secondary energy and can be provided by various primary energy sources, including fossil fuels, nuclear energy, solar energy, hydropower, wind energy and ocean energy.

The most abundant substance containing hydrogen is water, followed by various fossil fuels, mainly coal, oil, natural gas and various biomass. Therefore, in the long run, hydrogen production from water is the most promising method, and the raw materials are inexhaustible. After hydrogen combustion releases energy, it produces product water, which will not pollute the environment. Hydrogen production from various fossil fuels is the most important method at present, but its reserves are limited, and it not only consumes energy, but also consumes energy in the process of hydrogen production. At present, other hydrogen-containing substances are still in a secondary position, and some are under development. However, with the expansion of the application range of hydrogen energy, the requirements for hydrogen sources are getting higher and higher, and providing hydrogen sources is also a method. At present, from a big perspective, hydrogen production technology has both traditional methods and some new methods. Of course, with the development of science and technology, there will be other new hydrogen production methods.

There are five traditional hydrogen production technologies, namely, water electrolysis hydrogen production, fossil fuel hydrogen production, biomass hydrogen production, solar energy hydrogen production and photochemical hydrogen production. Details are as follows:
