Problems solved by technology

[0004] In the existing natural gas distributed energy, its equipment generates heat through the combustion of natural gas in one place to drive the steam turbine to generate electricity. Use at distribution points; in real life, it is difficult to integrate the generated electricity into the national grid, which affects the performance of economic benefits; hot water is lost in heat energy when it is transported through the pipe network, and sometimes the distribution point area is huge, and the corresponding cable and hot water pipe network The amount of layout project is huge, and the investment funds are also huge, which affects the overall economic benefits
[0005] If the distance between two identical natural gas distributed energy sources is long, they cannot be cross-supplied and cannot be connected into a network, which has regional and limitations
The distributed energy users between the two cannot be interchanged, cannot be moved, and the expansion ability is very weak
The existing natural gas distributed energy has no way to expand the radiation range, it can only be fixed in one place, and the users at the distribution point cannot "reproduce" energy radiation to more energy users
[0006] In short, natural gas distributed energy has losses from power generation, transmission, and client use through combustion. The number of client users at the distribution point is fixed. Once it is burned to generate electricity, the power supply cannot be satisfied when there are too many users, and the electricity cannot be stored if there are fewer users It causes waste, and heat energy cannot be consumed in summer, which also causes waste. This is the biggest disadvantage of natural gas distribution, and it is difficult to replicate on a large scale. In actual promotion and application, there are many constraints, and the efficiency of natural gas conversion to energy is very low

Embodiment 1

[0104] In this case, hydrogen production from renewable energy is preferred:

[0105] Build a solar photovoltaic power generation (photothermal power generation) station around the city. In order to improve hydrogen production efficiency and reduce costs, you can use fishing photovoltaic complementary photovoltaic power stations to set up solar photovoltaic panels on the water surface, which will not affect fish farming or power generation. ; There are also greenhouse photovoltaic power stations, etc. Hydrogen is produced by electrolyzing water on the power station, hydrogen compressors are installed at the hydrogen production point, and four refueling points are established in the city, respectively called: light 1 refueling point , light 2 gas filling point, light 3 gas filling point, light 4 gas filling point; where light 4 gas filling point is a fixed hydrogen fuel cell generator set filling point in the community;

[0106] Build a wind power station in another place aroun...

Embodiment 2

[0120] Set up large-scale hydrogen production plants around Beijing to reduce costs by centralized hydrogen production. The source of raw materials is LNG from Tianjin Caofeidian LNG receiving station; LNG is transported to Beijing in a short distance, the cost is very low, and LNG is very clean; the price of sea gas is very cheap; it can also be used Its cold energy reduces the exhaust gas temperature at the outlet of the hydrogen compressor;

[0121] exist figure 1 as shown in:

[0122] LNG is vaporized into a gaseous state, reformed to produce hydrogen or cracked to produce hydrogen (1), and the generated hydrogen is pressurized by the compressor (2) to fill the trailer of the gas storage cylinder (3) with hydrogen at a pressure of 85 MPa;

[0123] exist figure 1 In the figure, we can see that the gas cylinder group trailer (3) corresponds to many hydrogen refueling stations, and each hydrogen refueling station can correspond to many hydrogen refueling machines (4) to ref...

Abstract

A hydrogen refueling station network facility can inject hydrogen for hydrogen cell hydrogen storage cylinders in an area and forms a hydrogen distribution type energy resource together with hydrogen cells. The energy resources around a city are used for producing hydrogen through various hydrogen making methods. Energy resource conversion is realized through the procedures of pressurization, conveying, storage, air-entrapping and the like. A circular process including the procedures of hydrogen production, conveying with a gas storage cylinder set trailer, consumption of hydrogen cells, conveying with the gas storage cylinder set trailer and hydrogen production goes on all the time. The energy resource provided in the scheme does not use circuits of a power grid and is independent from the power grid, and the gas storage cylinder set trailer is used for supplying gas to the hydrogen cells as a movable pipeline. By means of the scheme, the greatest effect is that the city is changed into a hydrogen energy society, and zero emission is realized. If every city in China implements the scheme, China can develop into the hydrogen energy society soon, and great significance is achieved.

Description

technical field [0001] The invention relates to a network facility of a hydrogen refueling station, which realizes hydrogen filling for a hydrogen fuel cell hydrogen storage bottle in a region; together with the hydrogen fuel cell, a hydrogen distributed energy source is formed; the invention preferentially converts renewable energy into Hydrogen provides "power" for cities and replaces fossil energy. When every city successfully implements this case, our country has entered a hydrogen energy society with blue sky, white clouds and beautiful mountains and clear waters. The present invention belongs to the field of hydrogen energy. Background technique [0002] The existing hydrogen refueling stations in my country have backward technological processes, and they all use trailers with working pressures of 20MPa gas storage cylinders to transport hydrogen. There is a gas storage cylinder group, and there is a risk of explosion if there is hydrogen leakage; the daily gas refillin...
