Description

TECHNICAL FIELD

[0001] The present application relates to the field of offshore wind power technology, and in particular to a hydrogen production and storage system for a wind farm. BACKGROUND

[0002] With the rapid increase in installed capacity of wind power, a series of challenges have emerged. The uncontrollability of wind energy itself leads to significant fluctuations in wind power generation, which may cause wind and electricity to be abandoned when there is an excess of production capacity, resulting in waste of valuable wind energy resources, and may bring great difficulties to power grid dispatching when there is an insufficient production capacity. At the same time, for offshore wind power platforms far from land, the complexity of operation and maintenance and the transmission loss of electric energy are significantly aggravated as the distance from the shore increases. In addition, offshore wind power platforms also face multiple challenges such as cable routing planning, cable landing site selection, and marine space usage restrictions. Therefore, in order to make more effective use of abundant wind energy resources at sea, it is particularly urgent to explore new energy storage and energy conversion methods.

[0003] Traditional chemical energy storage methods cannot meet the needs of offshore wind power platforms due to the limited capacity of the energy storage devices used and the high maintenance costs. In contrast, wind power hydrogen storage technology stands out with its high capacity, easy transportation, environmental protection, and pollution-free advantages, and has become a promising energy storage solution in the field of offshore wind power. However, existing offshore wind power platform hydrogen production projects require a series of complex equipment such as hydrogen production and storage to be integrated compactly in a limited space, which poses high requirements for overall space arrangement. Moreover, hydrogen production and storage are concentrated together, which requires higher safety and more complex systems, and is not conducive to the development of commercial wind farms. In addition, existing deep-sea hydrogen transportation schemes mainly fall into two categories: one is a hydrogen pipeline transportation scheme, which can continuously transport large quantities of hydrogen, but faces leakage risks and maintenance difficulties during long-distance transportation, and has high costs; the other is a hydrogen ship transportation scheme, which can realize point-to-point transportation from the wind farm to the wharf and can enter the dock for maintenance on land, but the transportation is not continuous and requires two or more ships to cooperate, and the transportation capacity is smaller than the hydrogen pipeline transportation scheme.

[0004] Currently, the hydrogen production project on offshore wind power platforms commonly adopts the method of first storing hydrogen on the platform and then transferring it to the transport ship. However, this process faces two problems: first, high-pressure hydrogen gas or liquid hydrogen has a high risk of leakage during transfer, and second, there is energy loss during the transfer process.

[0045] Meanwhile, the wind power hydrogen production platforms 1 only electrolyze water to produce hydrogen and are not configured with hydrogen compression and storage functions. The low-pressure hydrogen of the wind power hydrogen production field is transmitted to the shuttle hydrogen storage ships 2 through the off-site hydrogen transmission pipes 4 for storage. When one shuttle hydrogen storage ship 2 is full, the connection with the off-site hydrogen transmission pipe 4 can be disconnected and returned to the wharf. Another shuttle hydrogen storage ship 2 reconnects the disconnected off-site hydrogen transmission pipe 4 and continues to store hydrogen.
