This will facilitate the unified implementation of regional integrated energy, contribute to regional carbon emission reduction, and offer excellent environmental and social benefits. First, it leverages the effects of technological integration to ensure energy supply security and quality.

Third, it fully utilizes renewable energy to reduce primary energy consumption and lower carbon emissions. Fourth, it leverages existing heating pipelines to provide cooling and heating services. Therefore, the unified utilization of regional integrated energy resources involves the development of new energy power generation, new energy vehicles, heating for production and daily life, and low-carbon renewable energy.

[0042] Example

[0043] This example is a bus parking lot for a bus company in Northwest China, located adjacent to the company's residential area. This company manages a small fleet of hydrogen-powered buses, and previously refueled them by building a small, self-built hydrogen refueling station that used city electricity to electrolyze water to produce hydrogen. This was costly, with low utilization rates and high fees.

[0044] In this embodiment, 10 sets of container-type hydrogen energy cogeneration and waste heat recovery devices are used. The external dimensions of the container body 1 of the device are 6058*2438*2896, the bottom plate and the wire trough cover are 4mm patterned plates, the side plates are 1.6mm corrugated plates, and the top plate is a container stamped top plate. The box circuit is an explosion-proof circuit, the lighting lamp 12 is equipped with 2+2 (small) explosion-proof lamps, the exhaust fan 8 uses 2 explosion-proof exhaust balls, explosion-proof switches, pure water machine 22 power single-phase AC 220V, 1.5kw, 1 explosion-proof distribution box, and the lines are exposed. Radiators and air conditioners are reserved (the air conditioner is reserved on the container), and pipe openings and fixed pre-buried are reserved. The bottom of the container body 1 is equipped with a wiring trough 6, the wiring trough 6 is 100mm deep, some of the wiring troughs 6 have partitions, and small holes are scattered under the wiring trough 6 for drainage. Box color: RAL9010. The box door is opened according to Figure 1 Layout. All wall-penetrating pipes are made of 316 stainless steel, with double flanges inside and outside, protruding 80mm from the wall. Lightning protection strips are installed on the top, extending diagonally from the outside to the bottom. All doors are equipped with rat guards, without the word "rat guard". Anti-static balls are installed on container doors. 3*1mm wires are threaded into galvanized pipes. 2 For RVVP shielded cable, allow 1 meter at the top and 3.5 meters at the bottom. Connect a DN25 galvanized pipe to the nearest 50-inch wide cable trough at the bottom of the box, leaving 1-inch male threads at both ends and marking them. All lighting power lines are laid in galvanized pipe, with one end exposed and connected to the cable trough in Room 1, and the other end connected to the lighting fixture.

[0045] The solar panels on the roof of the bus company's family quarters and the roof of the parking lot office area are connected to the control box 21 from the photovoltaic power supply and municipal power supply interface 27 as the main power source. At the same time, the municipal power supply is connected to the control box 21 from the photovoltaic power supply and municipal power supply interface 27 as the auxiliary power source, and the cooling water circulation port is connected to the heating supply pipeline of the parking lot office area building and the heating supply pipeline of the family quarters.

[0046] During the day when solar power generation is sufficient, the solar power generation is connected to the PEM hydrogen production cabinet 31 through the PEM control cabinet 23 for hydrogen production. When a hydrogen-powered vehicle stops and returns to the factory for hydrogen filling, the vehicle is filled with gas through the vehicle filling valve 44. The excess hydrogen is stored in a hydrogen tank at the hydrogen collection valve 42. The bus company's affiliated hospital and nearby farms use oxygen tanks to store oxygen at the oxygen collection valve 43 and then transport it to the place of use. When the supply of hydrogen and oxygen exceeds demand, the hydrogen is transported to the fuel cell 32 for redox power generation. The generated stable direct current can be used to charge the bus company's pure electric buses. At the same time, the heat generated and released by PEM hydrogen production and hydrogen redox power generation is transported to the cooling water circulation port 33 on the outer wall of the container through the cooling water circuit, and is used for heating the office building and the family building in the family area, making up for the energy loss of converting electrical energy into hydrogen energy and then into electrical energy.

[0047] At night, when the solar power generation capacity is weakest, the hydrogen tank stored during the day is connected to the mixing valve at the vehicle charging valve 44 to replenish the vehicle hydrogen. The insufficient part is connected to the PEM hydrogen production cabinet 31 using mains electricity to produce PEM hydrogen for vehicle charging. The heat generated and released by PEM hydrogen production at night is all used for heating the family building in the family area.

[0048] Therefore, this embodiment primarily relies on solar energy for hydrogen production during the day, with utility power used as a supplement only at night when solar energy is insufficient. Heat generated by PEM hydrogen production and hydrogen power generation is recovered for heating in the office and family quarters. This significantly reduces energy consumption and costs compared to previous methods that rely solely on utility power for water electrolysis to produce hydrogen.

[0049] To sum up, the present invention produces hydrogen through PEM after connecting solar power generation, wind power generation, tidal power generation and municipal power supply, uses or stores the produced hydrogen and oxygen according to different usage methods, or generates electricity through oxidation-reduction reaction of the produced hydrogen, converts unstable electric energy into stable electric energy, and uses the heat generated in the process of PEM hydrogen production and hydrogen energy power generation to produce hot water for daily life; the present invention can combine and complement multiple supply methods according to different external power supply forms and different energy supply requirements, therefore, the present invention has broad application prospects.

Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
