Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power storage equipment, in particular to a deep-sea floating power storage structure. Background Art
[0002] Green renewable energy has unlimited development potential. With the large-scale development of offshore wind power, it is an inevitable trend for offshore wind power to move from nearshore to deep sea. At present, deep sea wind power transmission mainly includes AC transmission, flexible DC transmission and offshore wind power hydrogen production. AC transmission is to transmit the AC power generated by offshore wind farms to land through submarine cables. However, there are problems of capacitance effect and difficulty in controlling reactive voltage compensation during long-distance transmission; flexible DC transmission is to use flexible transmission technology to convert the AC power generated by offshore wind farms into DC power for transmission. However, there are many power electronic devices in the converter of this method, which will produce large switching losses, resulting in an increase in the overall system loss, and its equipment cost and construction cost are relatively high, and the technical maturity needs to be improved.
[0003] Hydrogen production at sea consumes a lot of energy, and it also faces additional huge challenges brought by the complex chemical environment of seawater: First, seawater corrodes the electrolyzer. The composition of seawater is complex, such as dissolved ions, bacteria, impurities, etc., which corrode the electrolyzer components; second, impurities in seawater can cause catalyst deactivation. Impurities will deposit and adhere on the ion exchange membrane and catalyst surface, causing ion channels and catalytic active sites to be blocked, causing the catalyst to deactivate quickly. Third, the efficiency of seawater electrolysis is low. The concentration of hydrogen ions and hydroxide ions in seawater is very low. During the electrolysis process, the mass transfer rate is slow, making the electrolysis efficiency very low;
[0004] With the large-scale development of offshore wind power, considering factors such as resource potential and sea area land use, it is an inevitable trend for offshore wind power to move from nearshore to deep sea. Compared with nearshore wind farms, deep sea wind farms face more stringent requirements for transmission. The long-distance transmission of large-capacity offshore wind power is a technical problem that needs to be solved urgently for the development and utilization of deep sea wind power. Existing technologies such as submarine cable transmission and offshore hydrogen production face restrictive absorption problems such as long transmission distance, high cable transmission cost, and low offshore hydrogen production efficiency.
