Description
Technical Field
The present invention relates to a marine solar distributed power generation apparatus using solar power generation, and more particularly, to a marine solar power generation apparatus capable of stably supplying energy to an urban area near the sea or the like.
Background
At present, the need to control the carbon dioxide discharged into the atmosphere has made the transition from fossil fuels such as petroleum to clean energy with low carbon emission an epoch requirement. In the last years, when people consider the site selection problem of a solar power plant, a desert area is preferred, because the desert area is not worth money, and sunlight is sufficient. In fact, the situation of building a solar power plant on the sea is similar to that of a desert, the land is not occupied, and no sunlight shelters such as buildings and mountains are arranged on the periphery of the power plant. People have not previously considered the construction of solar power plants at sea because conventional solar panels do not withstand the corrosion of seawater. However, researchers in france and israel have successfully developed corrosion-resistant floating-on-water solar power generation systems, making the prospect of building solar power plants at sea bright.
In view of the current development of countries around the world, economically developed regions are mostly distributed in coastal cities, and the population of the regions is also very dense. In order to build large-scale solar power plants in the areas, people must compete for precious land resources. However, vast at sea near coastal areas are unoccupied. If the solar power plant is built on the sea, the solar power plant does not compete for the land with residents, and does not need to transmit power from a remote place, so that the power cost is low, and the energy waste is less.
The above-water solar power generation system can be built on the sea and also in a freshwater lake, so that the existing resources can be fully utilized, the power transmission cost is reduced, and more sufficient energy is provided for people.
Disclosure of Invention
The object of the present invention is to utilize a wide offshore facility laying area and efficiently supply energy to an energy supply target (e.g., along a marine city area). An offshore power generation unit having a plurality of floating power generation units according to the present invention includes a solar float having a plurality of solar floating units and an energy device positioned offshore proximate the solar float, and the solar floating units are configured to be sunlight powered. A solar cell panel is provided as a device body floating on the sea surface, and the energy device includes a base portion, a seawater electrolysis portion installed in the base portion, a storage portion, and a fuel cell power generation portion. The seawater electrolysis unit uses the power provided by the solar cell panel to electrolyze seawater to extract hydrogen, and the storage unit stores the hydrogen extracted by the seawater electrolysis unit. The fuel cell power generation unit generates power using the hydrogen gas stored in the storage unit and supplies power to the land-based electricity facility.
As described above, according to the offshore solar power generation device of the present invention, solar energy obtained by the solar float is converted into hydrogen gas by the seawater electrolysis unit and stored, and the stored hydrogen gas is stored by the fuel cell power generation unit. Therefore, solar energy is converted into electric power and supplied to an onshore electricity facility, thereby being able to meet the demand of an energy supply target in coastal urban areas and provide stable electric power.
Further, since the storage device for storing hydrogen is installed at sea, it is not necessary to transport it to other places, and thus it is possible to minimize damage even if an accident occurs. Since the solar float is composed of a plurality of solar float cells, the solar float has excellent flexibility, such as expansibility and shape change. By replacing the solar float device, the maintenance performance can be improved to cope with the occurrence of a failure.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, according to an embodiment of the present invention, an offshore solar power generation apparatus includes an energy device 10 and a solar float 20. Further, as shown, which is disposed near a shoreline of a critical urban area, electric power obtained by solar power generation of the solar float 20 is supplied to the energy device 10. In the energy device 10, seawater is first electrolyzed using hydrogen in the solar float 20 to extract hydrogen. The extracted hydrogen gas is temporarily stored in a storage device such as a storage tank. Using the hydrogen stored in the storage unit, the fuel cell power generation unit generates electric power and supplies it to the urban area. As described above, in the offshore solar power generation device according to the embodiment of the present invention, power obtained from the solar float 20 is converted into hydrogen and stored, thereby providing stable power to urban areas and the like for power supply. Further, in the present embodiment, heat generated when power is generated in the fuel cell power generation unit is also supplied to the energy supply target. Can be transferred by transferring heat to a heat medium (such as liquid or gas), the heat transported to the heat medium is transferred to city water or the like, and can be used for hot water supply. In the present embodiment, when the first side of the energy source device 10 is positioned at a position close to the land side, the solar float is positioned at a second side (opposite side in the present example) different from the first side. Therefore, by disposing the energy source device 10 at a position close to the energy supply target, the energy loss due to the distance can be reduced. The solar float 20 is made up of a plurality of solar float cells. By arranging the solar float 20 on the second side (sea side), the solar float can be enlarged and the shape of the solar float 20 can be changed according to the use state at sea.
As shown in fig. 2, in this embodiment, the solar float 20 is constructed by connecting solar float units 21 capable of floating on the sea surface to each other. A solar floating unit (e.g., 21 f) adjacent to the energy source device 10 is coupled to the base portion 14 of the energy source device 10. The positional fixing of the solar floating units is not limited to this form, and each solar floating unit may be fixed on the seabed by an anchor. The energy device 10 includes a base unit 14, a seawater electrolysis unit 11 provided on the base 14, a storage unit 12, and a fuel cell power generation unit 13, and supplies heat to a desired urban area. The transportation of electricity will be carried out using electric wires and heat will be carried using pipes that can carry a thermal medium, in this embodiment, since the storage means 12 storing hydrogen is installed at sea, further expansion of damage can be avoided even if an accident occurs. Further, since hydrogen stored in the storage unit 12 is converted into electric energy and supplied from the fuel cell power generation unit 13, transportation of hydrogen gas is not necessary, so there is no risk of transportation.
The base 14 of the energy device is arranged to sit on a building on the seabed or may be mounted as a facility that floats on the surface of the sea using a float, such as a solar powered float 20. When configured to float on the sea, it can reach a designated area and provide energy to shore-based targets in a short time by means of sea transport, ship towing, similar to the solar float 20.
