Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] The invention provides a method for preparing hydrogen by using multiple energy sources and supplying green energy, the steps are as follows:

[0037] 1) Use renewable energy (including solar energy, wind power, and tide) to generate power, and supply power to electrical equipment and water electrolysis devices;

[0038] 2) The water electrolysis device produces hydrogen through the mains and / or electricity obtained from renewable energy, and compresses and stores it;

[0039] 3) The hydrogen fuel cell uses the hydrogen produced in step 2) to generate power for electrical equipment and water electrolysis devices; to burn to provide heat;

[0040] 4) Purify and store the water produced by hydrogen fuel cells and hydrogen combustion.

[0041] Furthermore, in step 1), a rechargeable battery pack can also be added, and renewable energy ca...

Abstract

The invention relates to a method and a system of utilizing multiple energy sources to prepare hydrogen and supply a green energy source. The method comprises the steps of 1) utilizing a renewable energy source to generate electricity to supply power to the power equipment and a water electrolysis device separately; 2) using the water electrolysis device to prepare the hydrogen by the commercial power and/ or by utilizing the electric energy obtained by the renewable energy source, and compressing and storing the hydrogen; 3) using a hydrogen fuel cell to generate electricity via the hydrogen prepared in the step 2 to supply power to the power equipment and the water electrolysis device, and combusting the hydrogen to supply heat energy; 4) purifying and storing the water generated by the hydrogen fuel cell and by combusting the hydrogen. According to the present invention, various energy sources supply power, the spare electric power and the electric power at the power consumption low ebb are stored in the hydrogen manner via the sewage after the electrolytic treatment, the hydrogen fuel cell supplies the power when the electric power is insufficient or the electric power cost is higher, and fresh water also can be generated during the power supply process, thereby reducing the pollution and protecting the water resource.

Description

technical field [0001] The invention relates to an application field of energy conversion, and more specifically, relates to a method and a system for preparing hydrogen by using multiple energy sources and supplying green energy. Background technique [0002] The current green home has considered solar cells, wind turbines, and tidal generators. However, these types of energy sources are not stable enough, and when connected to the grid for power generation, the utilization rate is not high during the low power consumption period. At the same time, natural gas is mostly used as fuel in modern households. Compared with air, natural gas has a slightly larger specific gravity. It is not easy to dissipate after leakage, and it is easy to cause explosion and poisoning. It also produces toxic gases during combustion, which pollutes the environment. [0003] Chinese utility model patent ZL201220525716.X discloses a self-generating tunnel lighting system. Multiple piezoelectric de...
