The present invention relates to green energy, especially to a green hydrogen production system, a green power production system, a green hydrogen and green power production system, and methods of implementing the same.
Among a plurality of pollution sources which causes greenhouse effect, carbon dioxide is most effective. Carbon dioxide is released from the burning of fossil fuels. In order to reduce emissions of carbon dioxide, our dependency and use of fossil fuels should be limited. In Paris agreement, development of renewable energy and green hydrogen to replace fossil fuels has been proposed. However, most of methods of producing green hydrogen available now use water electrolysis to get green hydrogen and electricity used to split water comes from renewable energy such as solar energy and wind power. Thus the cost of green hydrogen from electrolysis is relatively high and difficult to compete with fossil fuels.
Therefore, it is a primary object of the present invention to provide a green hydrogen production system, a green power production system, a green hydrogen and green power production system, and methods of the same which produce green hydrogen and green power with reasonable price to solve problems of climate change and global warming caused by fossil fuels effectively.
In order to achieve the above object, a green hydrogen production system, a green power production system, a green hydrogen and green power production system, and methods of the same according to the present invention are provided. Catalyst for hydrogen production is sent to a raw-material mixing unit and mixed with water. Then a mixture of the catalyst for hydrogen production and the water is reacted in a first water splitting unit to have water splitting reaction therein and generate hydrogen gas and oxidized catalyst for hydrogen production. The hydrogen gas is delivered to a hydrogen power generation unit to produce green power while the oxidized catalyst for hydrogen production is sent to a photon-plasma decomposition unit for being reactivated and reduced into the catalyst for hydrogen production and oxygen generated is sent to the hydrogen power generation unit to generate power. Thereby green hydrogen and green power used in the system are recycled during operation. Raw materials including the catalyst for hydrogen production and water can also be recycled in the system. Therefore, green hydrogen and green power with reasonable price obtained can replace fossil fuels and problems caused by fossil fuels including climate change and global warming can be solved.
The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein:

When the present green hydrogen production system produces green hydrogen, the externally connected catalyst for hydrogen production is sent to the raw-material mixing unit 1 through the feed pipe. The catalyst for hydrogen production can be one of common metals (also called base metals), metal alloys, metal oxides, and their combinations. The preferred metal includes copper, iron, aluminum, tin, lead, zinc, sodium, calcium, lithium, potassium, nickel, magnesium, gallium, cadmium, silicon, titanium, etc. The preferred metal oxide includes copper peroxide [CuO2], ferric oxide [Fe2O3], ferrous ferric oxide [Fe3O4], aluminum oxide [Al2O3], stannic oxide [SnO2], lead dioxide [PbO2], zinc oxide [ZnO], sodium oxide [Na2O], calcium oxide [CaO], lithium oxide [Li2O], potassium oxide [K2O], nickel oxide [Ni2O], magnesium oxide [Mgo], gallium oxide [Ga2O3], cadmium oxide [CdO], silicon dioxide [SiO2], titanium oxide [TiO2], etc. The external water source supplies pure water which is sent to the raw-material mixing unit 1 by the water pipe. Thus the catalyst for hydrogen production and the water are mixed evenly in the raw-material mixing unit 1 and then a mixture of the catalyst for hydrogen production and the water is sent to the first water splitting unit 2 to perform water splitting reaction therein and generate hydrogen gas and oxidized catalyst for hydrogen production. A large amount of heat of enthalpy generated during production of the oxidized catalyst for hydrogen production and a small part of the catalyst for hydrogen production not completely reacted are released. Then the heat of enthalpy is absorbed by the first heat exchange module 21 of the first water splitting unit 2 and transferred to the heat recovery unit 3 by the heat transfer pipe. The catalyst for hydrogen production not completely reacted in the first water splitting unit 2 is sent to the heat recovery unit 3 by the feed pipe and the water from the external water source is also delivered to the heat recovery unit 3 by the water pipe. Now the heat of enthalpy and the water gathered allow the catalyst for hydrogen production not completely reacted to be excited and reacted completely to generate hydrogen gas and oxidized catalyst for hydrogen production. Next the hydrogen gas and the oxidized catalyst for hydrogen production generated by the first water splitting unit 2 and the heat recovery unit 3 are sent to the separation unit 4 through the feed pipes for separating the hydrogen gas (green hydrogen in gas form) and the oxidized catalyst for hydrogen production in solid form. The green hydrogen can be output from the system to the outside through the feed pipe for various applications. The oxidized catalyst for hydrogen production can also be sent to the outside to be used.

While generating green power by the green power production system of the present invention, the oxidized catalyst for hydrogen production produced by the present green hydrogen production system is used. The oxidized catalyst for hydrogen production is delivered into the photon-plasma decomposition unit 5 by the feed pipe for reactivation and reduction to produce catalyst for hydrogen production. Then the catalyst for hydrogen production produced is sent to the second water splitting unit 6 through the feed pipe to be reacted with water from the external water source to the second water splitting unit 6 through the water pipe. Thereby hydrogen gas and oxidized catalyst for hydrogen production are generated after water splitting reaction and a large amount of heat of enthalpy generated during production of the oxidized catalyst for hydrogen production is released. The heat of enthalpy is delivered to the second heat exchange module 51 of the photon-plasma decomposition unit 5 by the heat transfer pipe to be absorbed and used as a part of reduction heat for saving electricity and enhancing reductive degradation efficiency of the oxidized catalyst for hydrogen production. Moreover, the oxidized catalyst for hydrogen production generated in the second water splitting unit 6 is sent back to the photon-plasma decomposition unit 5 through the feed pipe to be recycled between the photon-plasma decomposition unit 5 and the second water splitting unit 6. While the oxidized catalyst for hydrogen production is reduced to the catalyst for hydrogen production in the photon-plasma decomposition unit 5, oxygen gas is also generated at the same time. The oxygen gas is sent to the hydrogen power generation unit 7 by the feed pipe while the hydrogen gas generated in the second water splitting unit 6 is also delivered to the hydrogen power generation unit 7 by the feed pipe to work together with the oxygen gas sent to the hydrogen power generation unit 7 for production of green power and water. The water generated by the hydrogen power generation unit 7 is sent to the second water splitting unit 6 by the water pipe to fill water required for water splitting reaction in the second water splitting unit 6. The green power generated can provide electricity required for system operation or output to the outside of the system for various applications. The oxidized catalyst for hydrogen production is a common metal, metal alloy, metal oxide, and a combination thereof. The preferred metal includes copper, iron, aluminum, tin, lead, zinc, sodium, calcium, lithium, potassium, nickel, magnesium, gallium, cadmium, silicon, titanium, etc. The preferred metal oxide includes copper peroxide [CuO2], ferric oxide [Fe2O3], ferrous ferric oxide [Fe3O4], aluminum oxide [Al2O3], stannic oxide [SnO2], lead dioxide [PbO2], zinc oxide [ZnO], sodium oxide [Na2O], calcium oxide [CaO], lithium oxide [Li2O], potassium oxide [K2O], nickel oxide [Ni2O], magnesium oxide [Mgo], gallium oxide [Ga2O3], cadmium oxide [CdO], silicon dioxide [SiO2], titanium oxide [TiO2], etc.

While in use, the externally connected catalyst for hydrogen production is delivered to the raw material mixing unit 1 by the feed pipe and water from the external water source is also sent to the raw material mixing unit 1 by the water pipe so that the catalyst for hydrogen production and the water are mixed evenly in the raw material mixing unit 1. Then a mixture of the catalyst for hydrogen production and the water is delivered to the first water splitting unit 2 to carry out water splitting reaction therein for producing hydrogen gas and oxidized catalyst for hydrogen production and releasing both a larger amount of heat of enthalpy generated during production of the oxidized catalyst for hydrogen production and a small part of the catalyst for hydrogen production not completely reacted. The heat of enthalpy is absorbed by the first heat exchange module 21 of the first water splitting unit 2 and delivered to the heat recovery unit 3 by the heat transfer pipe. As to the catalyst for hydrogen production not completely reacted in the first water splitting unit 2, it is delivered to the heat recovery unit 3 by the feed pipe and water from the external water source is also sent to the heat recovery unit 3 by the water pipe. Now the heat of enthalpy and the water gathered allow the catalyst for hydrogen production not completely reacted to be excited and reacted completely to generate hydrogen gas and oxidized catalyst for hydrogen production. Then the hydrogen gas and the oxidized catalyst for hydrogen production generated by the first water splitting unit 2 and the heat recovery unit 3 are sent to the separation unit 4 by the feed pipes for separating the hydrogen gas (green hydrogen in gas form) and the oxidized catalyst for hydrogen production in solid form. The green hydrogen can be used by the system or output from the system to the outside for various applications. The oxidized catalyst for hydrogen production is delivered into the photon-plasma decomposition unit 5 by the feed pipe for reactivation and catalyst for hydrogen production is obtained after reduction. Then the catalyst for hydrogen production produced is sent to the second water splitting unit 6 by the feed pipe for performing water splitting reaction. Thus hydrogen gas and oxidized catalyst for hydrogen production are generated and a large amount of heat of enthalpy generated during production of the oxidized catalyst for hydrogen production is released. The heat of enthalpy is delivered to the second heat exchange module 51 of the photon-plasma decomposition unit 5 by the heat transfer pipe to be absorbed and used as a part of reduction heat for saving electricity and enhancing reductive degradation efficiency of the oxidized catalyst for hydrogen production. As to the oxidized catalyst for hydrogen production generated in the second water splitting unit 6, it is sent to the heat recovery unit 3 by the feed pipe to be recycled among the heat recovery unit 3, the separation unit 4, the photon-plasma decomposition unit 5, and the second water splitting unit 6 in turn. While the oxidized catalyst for hydrogen production is reduced into the catalyst for hydrogen production in the photon-plasma decomposition unit 5, oxygen gas is also generated at the same time and then sent to the hydrogen power generation unit 7 by the feed pipe. Moreover, the hydrogen gas generated by the first water splitting unit 2 and the second water splitting unit 6 is delivered to the hydrogen power generation unit 7 by the feed pipes to react with the oxygen gas sent to the hydrogen power generation unit 7 and produce green power and water. The water produced in the hydrogen power generation unit 7 is sent to the second water splitting unit 6 by the water pipe to fill water required for water splitting reaction in the second water splitting unit 6. The green power generated by the hydrogen power generation unit 7 can provide electricity required for system operation or output to the outside of the system for various applications.

Thereby cost for green hydrogen and green power is significantly saved. Moreover, raw materials used in the system include catalyst for hydrogen production, water, etc. The catalyst for hydrogen production can be reactivated and recycled in the system after use and water is also recycled during operation of the system to reduce the amount of water from outside required significantly. Therefore, green hydrogen and green power with reasonable price obtained can be used to replace fossil fuels for effectively solving climate change and global warming issues caused by fossil fuels.
