Description

Technical Field

[0001] The present invention relates to a method for implementing a system for generating green hydrogen and green electricity.

Background Art

[0002] Among many pollution sources that cause the greenhouse effect, carbon dioxide emissions have the greatest adverse impact. Since carbon dioxide is emitted from fossil fuels, in order to reduce the amount of carbon dioxide emissions, it was necessary to reduce the dependence on and usage of fossil fuels. The Paris Agreement presented a solution to replace fossil fuels with renewable energy and green hydrogen. However, the conventional method for obtaining green hydrogen generated green hydrogen by water electrolysis and used renewable energy such as solar energy and wind power as the power source. Therefore, the price of the generated green hydrogen was very high, and it was difficult to replace fossil fuels with green hydrogen.

[0007] Refer to Figure 1. As shown in Figure 1, a green hydrogen and green electricity generation system according to one embodiment of the present invention includes a raw material mixing unit 1. The raw material mixing unit 1 is connected to the raw material transport pipe of the external hydrogen production catalyst, and the raw material mixing unit 1 and the first hydrolysis reaction unit 2 are connected to each other via the raw material transport pipe. The first hydrolysis reaction unit 2 and the heat recovery unit 3 are connected to each other via a raw material transport pipe. The first hydrolysis reaction unit 2 has a first heat exchange module 21, and the first heat exchange module 21 and the heat recovery unit 3 are connected to each other via heat transfer tubes. The green hydrogen and green electricity generation system of the present invention further comprises a separation unit 4. The heat recovery unit 3 is connected to the separation unit 4 via a raw material transport pipe. The green hydrogen and green electricity generation system of the present invention further comprises an electro-plasma decomposition unit 5. The photon-electrode plasma decomposition unit 5 is connected to the separation unit 4 via a raw material transport pipe. The photon-plasma decomposition unit 5 and the second hydrolysis reaction unit 6 are connected to each other via a raw material transport pipe. The electro-plasma decomposition unit 5 has a second heat exchange module 51. The second heat exchange module 51 and the second hydrolysis reaction unit 6 are connected to each other via heat transfer tubes. The second hydrolysis reaction unit 6 and the heat recovery unit 3 are connected to each other via a raw material transport pipe. The green hydrogen and green electricity generation system of the present invention further comprises a hydrogen energy power generation unit 7. The hydrogen energy generation unit 7 is connected to the photoplasma decomposition unit 5, the first hydrolysis reaction unit 2, and the second hydrolysis reaction unit 6 via a raw material transport pipe. The hydrogen energy generation unit 7 and the second hydrolysis reaction unit 6 are connected to each other via a water supply pipe. The raw material mixing unit 1 and the heat recovery unit 3 are each connected to a water supply pipe that is connected to an external water source. The hydrogen energy power generation unit 7 includes all hydrogen energy source power generation devices, such as hydrogen fuel cells including proton exchange membrane fuel cells (PEMFC: Polymer Electrolyte Fuel Cell) and solid oxide fuel cells (SOFC: Solid Oxide Fuel Cell), hydrogen internal combustion engines, or hydrogen turbines.

[0008] When actually using the green hydrogen and green electricity generation system of the present invention, the external hydrogen production catalyst is transported into the raw material mixing unit 1 via a raw material transport pipe. Hydrogen production catalysts are made from one of the following: common metals (also called base metals), metal alloys, metal oxides, or combinations thereof. The metals preferably include copper, iron, aluminum, tin, lead, zinc, sodium, calcium, lithium, potassium, nickel, magnesium, gallium, cadmium, silicon, titanium, and the like. Furthermore, metal oxides preferably include copper peroxide (CuO2), iron trioxide (Fe2O3), triiron tetroxide (Fe3O4), aluminum oxide (Al2O3), tin dioxide (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 dioxide (TiO2), and the like. An external water source supplies water to the raw material mixing unit 1 via a water supply pipe. The water is pure water. The hydrogen production catalyst and water are uniformly mixed in the raw material mixing unit 1. The mixture of hydrogen production catalyst and water is transported to the first hydrolysis reaction unit 2 via the raw material transport pipe. In the first hydrolysis reaction unit 2, the mixture undergoes a hydrolysis reaction to produce hydrogen and hydrogen oxide production catalyst. A large amount of heat content is released when the hydrogen oxide production catalyst is produced, as well as some of the hydrogen production catalyst that has not yet completely reacted. This heat content is absorbed by the first heat exchange module 21 installed in the first hydrolysis reaction unit 2 and transmitted to the heat recovery unit 3 via the heat transfer pipe. The hydrogen production catalyst that has not yet completely reacted in the first hydrolysis reaction unit 2 is transported to the heat recovery unit 3 via the raw material transport pipe. An external water source supplies water to the heat recovery unit 3 via a water supply pipe. The collected heat content and water excite the still-unreacted hydrogen production catalyst, causing it to react completely and generate hydrogen and hydrogen oxide production catalysts. The hydrogen and hydrogen oxide production catalyst generated by the heat recovery unit 3 and the first hydrolysis reaction unit 2 are transported to the separation unit 4 via the raw material transport pipe, where the separation unit 4 separates them into gaseous green hydrogen and solid hydrogen oxide production catalyst. Green hydrogen may be provided for use in the system, or it may be output outside the system for use in various applications. The hydrogen oxide production catalyst is transported to the photoplasma decomposition unit 5 via the raw material transport pipe, where it is newly activated, deoxygenated, and then reduced to produce a hydrogen production catalyst. The reduced hydrogen production catalyst is then transported to the second hydrolysis reaction unit 6 via the raw material transport pipe, where it is hydrolyzed to produce hydrogen and hydrogen oxide production catalyst, and a large amount of heat of enthalpy is released when the hydrogen oxide production catalyst is produced. The heat content is transferred via heat transfer tubes to the second heat exchange module 51 installed in the photovoltaic plasma decomposition unit 5 and absorbed. Some of the reduction heat is used in the photovoltaic plasma decomposition unit 5 to reduce power consumption and increase the reductive decomposition efficiency of the hydrogen oxide production catalyst. The hydrogen oxide production catalyst generated by the second hydrolysis reaction unit 6 is transported to the heat recovery unit 3 via a raw material transport pipe and can be sequentially and repeatedly circulated and reused between the heat recovery unit 3, the separation unit 4, the photovoltaic plasma decomposition unit 5, and the second hydrolysis reaction unit 6. The electro-plasma decomposition unit 5 reduces the hydrogen oxide production catalyst to generate a hydrogen production catalyst and also generates oxygen. Oxygen is transported to the hydrogen energy power generation unit 7 via a raw material transport pipe. The hydrogen produced by the first hydrolysis reaction unit 2 and the second hydrolysis reaction unit 6 is transported to the hydrogen energy power generation unit via a raw material transport pipe, and together with the oxygen transported to the hydrogen energy power generation unit 7, it generates green electricity and water. The water generated by the hydrogen energy power generation unit 7 is supplied to the second hydrolysis reaction unit 6 via a water supply pipe, replenishing the water necessary for the second hydrolysis reaction unit 6 to perform hydrolysis. The green electricity generated by the hydrogen energy power generation unit 7 can supply the power necessary for the system's operation and may also be output outside the system for various applications.

[0009] The present invention can be self-sufficient in green hydrogen and green power used in the system while operating the system, and can perform circulation continuously without interruption. Moreover, green hydrogen can be produced without using water electrolysis, and it is not necessary to use renewable power such as solar energy and wind power, so the cost of purchasing green hydrogen and green power can also be effectively reduced. In addition, the raw materials such as the hydrogen production catalyst and water that need to be used in the system can be newly activated by the system and recycled continuously even after the hydrogen production catalyst is used. In addition, during the operation of the system, water can be recovered and reused, so the required amount of external water can be significantly reduced. Thus, since the present invention can obtain inexpensive green hydrogen and green power, it can effectively replace fossil fuels and effectively solve the problems of global climate change and global warming. In addition, the present invention has features such as reversibility and interchangeability in the generation of green hydrogen and green power. Therefore, it is also possible to produce and store green hydrogen during the night when the electricity cost is low, and use the green hydrogen to generate green power during the daytime peak. Since it can be implemented in various flexible ways like this, the income can be increased and the economic benefit can be enhanced. In addition, the system of the present invention can generate green hydrogen by adding water when using hydrogen according to the on-site and on-demand requirements. Thus, since solid hydrogen production catalyst is used to generate green hydrogen, problems such as the risks and high costs during the storage and transportation of hydrogen can be effectively solved.

[0010] Here, as shown in FIG. 2, the electro-optical plasma decomposition unit 5 of the present invention may have a second heat exchange module 51 attached to the outside of the unit main body 52. Inside the unit body 52, an artificial lightning module 53, an electro-optical plasma decomposition module 54, an energy storage and re-regulation module 55, and a separation and purification module 56 are sequentially provided. After entering the electro-optical plasma decomposition unit 5, the hydrogen oxide production catalyst sequentially performs artificial lightning treatment, electro-optical plasma decomposition treatment, energy storage and re-regulation treatment, and separation and purification treatment to reduce the hydrogen oxide production catalyst and generate a hydrogen production catalyst. Here, by using the electro-optical plasma decomposition unit 5, the hydrogen oxide production catalyst can be newly activated, deoxygenated, reduced, and a new hydrogen production catalyst can be generated and reused.

[0011] As can be seen from the above, the green hydrogen generation system, green power generation system, and the method for implementing the green hydrogen and green power generation system of the present invention have the following advantages (1) to (6). (1) The present invention can self-supply and circulate each of the green hydrogen and green power used in the system during system operation without interruption. In addition, green hydrogen can be generated without using water electrolysis, and there is no need to use renewable power such as solar energy and wind power, so the cost of purchasing green hydrogen and green power can be effectively reduced. (2) The present invention can reactivate and circulate the raw materials such as the hydrogen production catalyst and water that need to be used in the system even after using the hydrogen production catalyst. In addition, during the process of system operation, water is recovered and reused, so the required amount of external water can be greatly reduced and the cost can be saved. (3) The present invention can recover and reuse the raw materials such as the hydrogen production catalyst and water that need to be used in the system during the process of system operation, so inexpensive green hydrogen and green power can be obtained. Since the production cost of the green hydrogen is lower than that of the prior art method, the industrial competitiveness is high. (4) The system of the present invention can produce green hydrogen by adding water to hydrogen when it is used, according to the required amount on site and on demand. In this way, since green hydrogen is produced using a solid hydrogen production catalyst, problems such as difficulties and high costs in hydrogen storage and transportation can be effectively solved. (5) The system of the present invention can provide inexpensive green hydrogen and green electricity, thus effectively replacing fossil fuels and effectively solving the problems of global climate change and global warming. As a result, it can increase income and boost economic returns. (6) Because the system of the present invention has features such as reversibility and interchangeability of green hydrogen and green electricity, green hydrogen can be generated during off-peak hours when electricity rates are low, and green electricity can be generated during off-peak hours when electricity rates are high. In this way, it can be implemented flexibly in various ways, resulting in high economic returns. [Explanation of Symbols]
