Description
Technical Field
The utility model relates to the technical field of new energy, in particular to a photovoltaic hydrogen production and hydrogenation integrated station structure.
Background
Since the aim of carbon neutralization is put forward in China, more and more hydrogenation stations are built for automobiles in various places, and the hydrogenation stations can hydrogenate hydrogen fuel cell buses, hydrogen fuel cell cars and hydrogen fuel cell trucks. Since hydrogen only produces water during driving the automobile, it is considered to be environmentally friendly and low in carbon.
However, more than 96% of hydrogen in China is prepared by coal chemical industry process, belongs to ash hydrogen, and a large amount of carbon dioxide is discharged in the hydrogen production process. Therefore, the hydrogen prepared by adopting the coal chemical industry process as the hydrogen source of the hydrogen filling station does not conform to the technical route of carbon neutralization, and belongs to pollution transfer.
Because the hydrogen production station and the hydrogen station are not designed and supplied by the same main body, the hydrogen production station and the hydrogen station of some design houses are not designed by the same professional. Therefore, in a practical situation, the hydrogen production system and the hydrogenation system are respectively provided with a cooling device. Significant resources would be saved if the cooling system could be orchestrated such that the cooling device serves both the hydrogen production system and the hydrogenation system.
The hydrogen cost of the hydrogen station is increased and the transportation risk is increased due to the fact that the hydrogen station and the hydrogen station are separately built through hydrogen transportation and other factors. Most of the existing hydrogen production stations are chemical engineering methods for producing hydrogen, the carbon emission intensity is high, and the carbon neutralization target is not easy to realize. The separate construction of the hydrogen production station and the hydrogen filling station is not beneficial to centralized management and centralized control.
In summary, it is necessary to provide a process route for generating electricity by renewable energy sources only for hydrogen production and hydrogenation. The whole process of generating hydrogen, hydrogenating and using hydrogen by renewable energy sources has zero carbon emission and accords with the strategic target of carbon neutralization.
