Detailed Description

The technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Currently, no standard definition and formula exist for the hydrogen production cost in the industry, and each user usually performs hydrogen production cost analysis according to own service range and service understanding. However, due to differences in cognition and expertise, hydrogen production cost analysis is often not considered comprehensive enough in many cases, for example, omission of some key influencing factors, or failure to analyze hydrogen production cost at a depth level sufficiently, and so on.

In addition, the current hydrogen production cost analysis mostly considers stable net electricity as energy supply. However, with the advent of the green-to-green hydrogen age supplied by renewable energy as an energy source, the hydrogen production cost analysis system has also, overall, the following problems:

(1) The hydrogen production cost analysis process does not incorporate carbon emission factors, and the advantages of green hydrogen cannot be fully displayed, so that the trend of future hydrogen production development is reflected;

(2) The performance change condition of the electrolytic tank in the whole life cycle of hydrogen production, namely the attenuation of yield or energy consumption, is not considered in the hydrogen production cost analysis process;

(3) The hydrogen production cost analysis process is not extensible, and partial modules cannot be incorporated into a unified analysis system when combined with upstream and downstream;

(4) The value of the byproduct oxygen is ignored in the analysis process of the hydrogen production cost, and the influence of the byproduct on the hydrogen production cost is not considered.

Aiming at the problems, the embodiment of the application provides a unified and standardized hydrogen production cost analysis method, which brings parameters in multiple dimensions into a normalized analysis standard and establishes a mature hydrogen production cost analysis system. And will be described in detail below.

Referring to FIG. 1, a system architecture diagram for hydrogen production cost analysis is shown in accordance with an embodiment of the present application.

In embodiments of the application, project parameters of the hydrogen production system may include, but are not limited to, initial investment costs, operating costs, hydrogen production, and the like.

In an alternative embodiment, if only the own module of the hydrogen production link of the hydrogen production system is considered and the external module of the hydrogen production link is not considered, the process of obtaining the initial investment cost of the hydrogen production system may include: and acquiring the basic initial investment cost of the hydrogen production system, and determining the basic initial investment cost of the hydrogen production system as the initial investment cost of the hydrogen production system.

The initial investment cost of the equipment, the initial investment cost of the factory building, the initial investment cost of the land and the additional initial investment cost can be obtained from project feasibility research reports.

In this case, initial investment cost I of Hydrogen production System ₀ The expression can be expressed by the following formula:

Accordingly, the basic operational costs of the hydrogen production system may include the basic operational costs of each sub-cycle hydrogen production system within the total operational cycle of the hydrogen production system. Specific values of the total operation period and the sub-period can be set according to actual project requirements, and the embodiment of the application is not limited to this. For example, if the total operating period is n years, it may be one sub-period every 1 year, and so on.

Thus, the core of cell performance degradation is manifested as a sub-cycle increase in hydrogen production electricity usage (e.g., annual hydrogen production electricity usage). Therefore, in the embodiment of the application, in the process of obtaining the production cost of the hydrogen production system, the influence generated by the performance change of the electrolytic tank can be added, so that the accuracy of hydrogen production cost analysis is further improved.
