Description

Technical Field

[0001] This application relates to the field of hydrogen energy technology, and particularly to a hydrogen hybrid energy storage system and method suitable for industrial parks. Background Technique

[0002] The statements in this part merely provide background technical information related to this application and do not necessarily constitute prior art.

[0003] Hydrogen energy is a secondary energy source with rich sources, green and low-carbon, and wide applications, and is gradually becoming one of the important carriers for the global energy transformation and development. Hydrogen energy has diverse conversion forms, is suitable for large-scale and long-term energy storage, and can also store energy over long distances, which helps to solve the problem of new energy consumption. The development and utilization of hydrogen are expected to contribute to solving the problem of sustainable development of future energy. The production of raw material hydrogen has become one of the important links in the current engineering application of hydrogen energy. It is urgent to seek a hydrogen production method that is cheap, environmentally friendly, and suitable for large-scale production, and to promote the construction of a clean, low-carbon, and low-cost diversified hydrogen production system.

[0004] China is the world's largest country in terms of industrial by-product hydrogen, with unique conditions for using by-product hydrogen. Moreover, the purification of industrial by-product hydrogen to produce high-purity hydrogen requires almost no additional capital and fossil raw material input, which not only saves costs but also enables the treatment and recycling of industrial waste gas. The obtained hydrogen has significant advantages in terms of cost and emission reduction and is suitable for large-scale promotion and development. The chlor-alkali industry is a basic industry in China, and the amount of by-product hydrogen in the chlor-alkali industry is very large. About 24 kilograms of by-product hydrogen can be produced for every 1 ton of caustic soda produced. At present, there are nearly 200 chlor-alkali production enterprises in China, and the stable production of by-product hydrogen can exceed 7 million tons. Although many chlor-alkali enterprises are equipped with polyvinyl chloride and hydrochloric acid production lines to utilize by-product hydrogen, the utilization rate is only about 60%. Therefore, 14,000 tons of by-product hydrogen can be left every year, showing great potential for the application of raw material hydrogen.

[0005] The chlor-alkali chemical industry is widely distributed, and the production bases coincide with the potential hydrogen load centers, making it a good choice for hydrogen cost resources. To promote the consumption of renewable energy power generation and the local recycling and utilization of industrial by-product hydrogen, China has proposed to build a modern energy system with interconnection of multiple energy sources. At the energy supply end, the large-scale and efficient utilization of renewable energy production and storage and industrial by-product hydrogen are coupled, promoting the integration of hydrogen energy, electric energy, and thermal energy systems, and facilitating the formation of a diversified, complementary, integrated, green, and efficient comprehensive energy supply system.

[0006] Hydrogen hybrid energy storage exhibits efficient and flexible advantages in aspects such as new energy consumption, electricity-hydrogen-electricity conversion and storage, and rapid response, realizing the large-scale application of renewable energy-hydrogen energy-electricity, and promoting the formation of a green, low-carbon, and efficient new energy supply system.

[0007] Starting from promoting the development of the hydrogen energy industry and aiming at "distributed + on-site consumption", a demonstration project for integrated hydrogen production, storage and utilization in multiple ways is built. A hydrogen production mode of electrolyzing water by coupling "photovoltaic + battery" is formed, and it is combined with low-cost and high-efficiency industrial by-product hydrogen purification technology to provide hydrogen and oxygen for the industrial parks around xx County and connect to the surrounding hydrogen energy refueling vehicles. This hydrogen hybrid energy storage system can provide peak shaving capacity for the power grid operation of xx Industrial Park in xx County and improve energy independence.

[0008] Disadvantages of the prior art:

[0010] 2. The quality of hydrogen produced by electrolyzing water is good, but the cost is high. Seeking a cheap, environmentally friendly and suitable hydrogen production method for large-scale production is an urgent problem to be solved. Summary of the Invention

The electrolytic water hydrogen production system includes two electrolytic water hydrogen production methods, proton exchange membrane electrolytic water hydrogen production (PEM) and anion exchange membrane electrolytic water hydrogen production (AEM). The proton exchange membrane electrolytic cell has a fast response, a wide load range, and flexible operation, and is suitable for hydrogen production scenarios with large fluctuations in photovoltaic power generation. The anion exchange membrane electrolytic cell combines the dual advantages of low cost of alkaline electrolytic cells and high efficiency and fast response of proton exchange membrane electrolytic cells, and is one of the preferred technologies for green hydrogen applications.

Among them, the methods of electrolytic water hydrogen production include proton exchange membrane electrolytic water hydrogen production and anion exchange membrane electrolytic water hydrogen production. During the day, electrolytic water and pressure swing adsorption purification of by-product hydrogen from the chlor-alkali industry work together to produce hydrogen as the hydrogen source for the hydrogen-using module. The two electrolyzers use photovoltaic power generation and lithium iron phosphate battery DC off-grid hydrogen production. At night, the purified by-product hydrogen from the chlor-alkali industry serves as the hydrogen source for the hydrogen-using module.

[0063] Step 3: Store the hydrogen produced by electrolytic water in Step 2 and send it to the hydrogen-using module through pipelines.

[0064] Specifically, the hydrogen produced by electrolytic water in Step 2 is stored, equipped with 1 set of 2MPa solid hydrogen storage device, and transported to the hydrogen-using module through pipelines. The hydrogen produced by pressure swing adsorption purification of by-product hydrogen from the chlor-alkali industry is transported to the hydrogen-using module through pipelines.
