Pillars are fixed above the ballast tanks, supporting decks. A living quarters are located on the bow deck, while a deckhouse and wind turbine power generation system are located on the stern deck. The deckhouse contains water electrolysis hydrogen production blocks, a hydrogen catalytic methanol production module, and a methanol storage module. Aquaculture modules are located between the pillars, each consisting of an aquaculture frame and netting, with the frame surrounded by netting. Feed and catch storage compartments are located within the pillars in the middle of the floating hull. This invention converts wind power, which is disadvantageous for long-range transmission, into easily stored green and clean energy, reducing transmission costs. Simultaneously, it utilizes the wind power platform to develop green long-range aquaculture, achieving "zero" fossil fuel-based green marine ranching.

Description

Technical Field

[0001] This invention belongs to the field of shipbuilding and design, and specifically relates to a semi-floating marine integrated platform for hydrogen and methanol production and aquaculture. Background Technology

[0002] With the continuous development of shallow-water wind farms, the water depth of suitable wind farms is constantly increasing, with some areas reaching depths of over 50 meters. The use of floating wind power platforms will become an inevitable requirement in these areas.

[0003] As new wind farms are increasingly located further offshore, the cost of using and installing submarine power transmission cables to transmit electricity back to land will become more expensive, and power transmission losses will increase, severely impacting the economic viability of offshore wind power platforms. Because wind speed variations are random, the electricity generated by wind power is also random, reducing the reliability of wind power capacity and making it difficult to balance active and reactive power in the power grid. Therefore, directly converting wind energy into other energy forms for storage is more economical than transmitting it back to land via cables.

[0004] Hydrogen is a clean fuel, but the production of hydrogen through water electrolysis requires a large amount of water resources and electricity, which is precisely the advantage of offshore wind turbines producing hydrogen. However, hydrogen also has the natural disadvantage of being difficult to store.

[0005] By using hydrogen as a raw material and wind power as an energy source, methanol, which is difficult to store, can be produced from hydrogen and is easy to store. This solves the problem of energy conversion and storage on offshore wind power platforms, and the resulting methanol is also a green fuel and chemical raw material.

[0006] Semi-floating platforms are relatively large, and using them solely for wind turbine power generation to produce hydrogen and methanol is not cost-effective. Extending wind power platforms into aquaculture platforms not only aligns with the trend of green marine ranching and reduces the cost of separate wind power and aquaculture platforms, but also allows the electricity generated by the wind power platform to directly power the aquaculture modules. By incorporating wind power platforms, the new type of wind-powered aquaculture platform can achieve true "zero" carbon emissions for green aquaculture, eliminating the need for fossil fuels.

[0007] With its green energy and green aquaculture platform, it can also develop marine green leisure functions, allowing ordinary people to access advanced green energy and green aquaculture industries, utilizing wind turbine energy and aquaculture catches to form green ecotourism, while increasing the platform's economic benefits. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides a semi-floating marine integrated platform for hydrogen and methanol production and aquaculture, the technical solution of which is as follows: A semi-floating marine integrated platform for hydrogen and methanol production and aquaculture has a lower floating body with multiple ballast tanks symmetrically arranged on both sides of the lower floating body. The ballast tanks are fixed with columns, and the columns support decks. The bow deck is equipped with a living quarters, and the stern deck is equipped with a deckhouse and a wind turbine power generation system. The deckhouse is equipped with water electrolysis hydrogen production wood blocks, a hydrogen catalytic methanol production module, and a methanol storage module.

[0009] Marine aquaculture modules are set between the pillars. Each marine aquaculture module consists of an aquaculture frame and a net. The aquaculture frame is surrounded by a net.

[0010] The feed tank and catch tank are located inside the column in the middle of the float.

[0011] Furthermore, the aforementioned semi-floating marine integrated platform for hydrogen and methanol production and aquaculture further includes a wind turbine power generation system composed of blades, hubs, and a wind turbine tower.

[0012] The aforementioned semi-floating marine integrated platform for hydrogen and methanol production and aquaculture further incorporates support pillars that form a framework for aquaculture modules, with netting hanging on the framework.

[0013] The aforementioned semi-floating marine integrated platform for hydrogen and methanol production and aquaculture has a further feature: the lower floating body is square, and four ballast tanks are provided on each of the two sides.

[0014] Furthermore, the aforementioned semi-floating marine integrated platform for hydrogen and methanol production and aquaculture is further equipped with six aquaculture modules. The aquaculture frames of the six aquaculture modules are interconnected, forming an overall grid pattern.

[0015] Furthermore, the aforementioned semi-floating marine integrated platform for hydrogen and methanol production and aquaculture is equipped with a walkway on top of the aquaculture frame.

[0016] Furthermore, the aforementioned semi-floating marine integrated platform for hydrogen and methanol production and aquaculture has a lower floating body that is 100m long, 40m wide, and 15m deep.

[0017] This invention uses hydrogen as a raw material and wind power as an energy source to convert hydrogen, which is difficult to store, into methanol, which is easy to store. This solves the problem of energy conversion and storage on offshore wind power platforms, and the resulting methanol is also a green fuel and chemical raw material.

[0018] Semi-floating platforms are relatively large, and using them solely for wind turbine power generation to produce hydrogen and methanol is not cost-effective. Extending wind power platforms into aquaculture platforms not only aligns with the trend of green marine ranching and reduces the cost of separate wind power and aquaculture platforms, but also allows the electricity generated by the wind power platform to directly power the aquaculture modules. By incorporating wind power platforms, the new type of wind-powered aquaculture platform can achieve true "zero" carbon emissions for green aquaculture, eliminating the need for fossil fuels.

[0019] With its green energy and green aquaculture platform, it can also develop marine green leisure functions, allowing ordinary people to access advanced green energy and green aquaculture industries, utilizing wind turbine energy and aquaculture catches to form green ecotourism, while increasing the platform's economic benefits.

[0022] A semi-floating marine integrated platform for hydrogen and methanol production and aquaculture, such as Figure 1-4As shown, the main structure 1 of the platform is approximately 100m long, 40m wide, and 15m deep. There are four outer pillars 2 on each of the port and starboard sides of the platform. The stern pillar of the platform has a wind turbine power generation system consisting of blades 3, hubs 4, and wind turbine towers 5. The platform has a top deck 6, which is supported by pillars 7 around the platform. This support structure simplifies the deck support structure and reduces costs without reducing the deck area. The platform has six aquaculture modules 8, with netting 9 around the modules to prevent fish from escaping. The netting is attached to the pillars. Feed tanks and catch tanks 10 are located inside the outer pillars near the center of the ship, used to store feed for aquaculture and temporarily store caught fish. The platform has a ring-shaped platform subfloor 11 structure to support the outer pillars and... The platform features a pillar structure; a living quarters 12 are located on the bow deck for tourists to reside and enjoy; the top deck of the bow platform extends outward from the living quarters to accommodate other recreational facilities for tourists; a deckhouse 13 is located on the stern deck, housing a hydrogen electrolysis and methanol production module 14 and a methanol storage module 15, used to convert the electricity generated by the wind turbine power generation system into easily stored green methanol. Once a certain amount of methanol is stored, it is transported to land by transport ships for use; a grid walkway 16 is arranged using the pillar structure between the aquaculture modules to facilitate passage between the modules; ballast water tanks 11 are installed on the lower floating body and the bottom area of ​​the outer pillars of the platform to adjust the platform's draft; four mooring systems 18 are installed at the bow and stern decks of the lower floating body to anchor the platform in the operating waters.

[0023] This patent enables wind turbines to generate green energy even in deep water exceeding 50 meters in depth. It utilizes wind power to electrolyze water to produce hydrogen, overcoming the drawbacks of wind power platforms far from shore, such as high power transmission costs, significant power loss, and excessive power consumption on the grid. Furthermore, it uses hydrogen as a raw material to produce easily storable methanol, overcoming the difficulty of storing large quantities of hydrogen. The resulting methanol is also a green fuel and chemical raw material. Semi-floating platforms are bulky, and using them solely for wind turbine power generation to produce hydrogen and methanol is not cost-effective. This patent extends the wind power platform to a marine aquaculture platform, aligning with the trend of green marine ranching, reducing the cost of separate wind power and aquaculture platforms, and allowing the electricity generated by the wind power platform to directly power the aquaculture modules. Combined with a wind power platform, this new wind-powered aquaculture platform can provide energy without using fossil fuels, achieving truly zero-carbon emissions for green aquaculture. This patent is for a platform with green energy and green aquaculture, which can develop marine green leisure functions, allowing ordinary people to access advanced green energy and green aquaculture industries, and utilize wind turbine energy and aquaculture catches to form green ecotourism, while increasing the platform's economic benefits.

[0024] This invention transforms wind power, which is disadvantageous for long-distance offshore transmission, into easily stored green and clean energy, reducing transmission costs. Simultaneously, it utilizes wind power platforms to develop green offshore aquaculture, achieving "zero" fossil fuel-based green marine ranching. This yields high-value aquaculture products while reducing the overall cost of both the wind power and aquaculture platforms. The platform generates green energy and provides green marine ranching services, making it suitable as a marine recreation base, offering eco-friendly marine tourism projects.

[0025] The types of green and clean energy can be replaced. The energy conversion model used in this patent is: wind energy - electricity - water electrolysis to produce hydrogen - hydrogen catalytic production to produce methanol - methanol storage. The "water electrolysis to produce hydrogen - hydrogen catalytic production to produce methanol - methanol storage" can also be replaced with other green energy sources that are easy to produce and store.

[0026] This project is an environmentally friendly eco-tourism project. If the overall economic efficiency of the platform is affected by factors such as remote operating areas, low visitor traffic, and poor economic performance, the relevant marine tourism modules of the platform can be cancelled to reduce the overall cost.
