The hosting of the Beijing 2022 Winter Olympics and Winter Paralympics has brought Zhangjiakou's hydrogen energy industry development map into the public eye. Today's series of reports on "Key Projects for High-quality Development" goes to the site of Hebei Construction Investment's wind power hydrogen production project in Chongli District, Zhangjiakou City, to see the support of green electricity and accelerate the development of the entire chain of the hydrogen energy industry. Yang Nan, reporter at Zhangjiakou Radio and Television Station: During the 2022 Winter Olympics, the 623 hydrogen fuel vehicles operating in the Zhangjiakou competition area became a beautiful scenery outside the stadium. So where does the hydrogen for hydrogen fuel vehicles come from? Today we have come to the site of the Hebei Construction Investment Wind Power Hydrogen Production Project in Chongli District, Zhangjiakou City, and will take you to find the answer. This is the workshop of the Hebei Jiantou Wind Power Hydrogen Production Project. The large cylindrical thing next to me is called an electrolyzer. The electricity generated by the photovoltaic and wind turbines built in the project is input into the electrolyzer, and the water is electrolyzed into oxygen and hydrogen. It then passes through the purification equipment to absorb impurities and separate oxygen, and hydrogen with a purity of 99.999% is obtained. Ma Bin, head of the hydrogen energy management department of Hebei Construction Investment New Energy Zhangjiakou Regional Company: The total investment in the first phase of the project is 230 million yuan, mainly for the production of green hydrogen, with an annual output of 313 tons and an output value of 6.89 million yuan. Yang Nan, reporter at Zhangjiakou Radio and Television Station: Utilizing Zhangjiakou's abundant wind and photovoltaic resources to develop secondary energy hydrogen energy may not sound complicated and mutually beneficial, but the technical team of the Hebei Construction Investment Wind Power Hydrogen Production Project has overcome many difficulties. Li Peng, deputy manager of Chongli County Company of Hebei Construction Investment New Energy Zhangjiakou Regional Company: Wind turbines and photovoltaic power generation are subject to environmental, weather and other factors, and the voltage is very unstable. As the world's first off-grid wind-solar coupling renewable energy water electrolysis hydrogen production project through DC microgrid transmission, in layman's terms, it can produce hydrogen without an external power supply. When hydrogen is not produced, renewable energy power can also be transmitted to the grid. Hydrogen can be divided into gray hydrogen, blue hydrogen and green hydrogen based on the production process. Gray hydrogen and blue hydrogen will produce carbon emissions, so there is a consensus in the energy industry that "grey hydrogen is not desirable, blue hydrogen can be used, and green hydrogen is the way forward." Green hydrogen uses renewable energy in the production process, such as wind power, hydropower, solar energy, etc., which is called zero-carbon energy. It is not only green and environmentally friendly, but also solves the problem of electrolytic water hydrogen production being subject to electricity prices and high production costs. Chen Xiaoyu, Hydrogen Energy Management Department, Hebei Construction Investment New Energy Zhangjiakou Regional Company: Compared with coal power, the cost of producing one ton of hydrogen fuel with green power is 50% lower. The reduction in hydrogen production costs provides conditions for the large-scale market application of hydrogen energy. Gain development initiative through technological innovation. After the Hebei Construction Investment Wind Power Hydrogen Production Project reaches full production, the hydrogen energy production capacity will reach more than 600 tons, laying a solid foundation for the company to integrate into the Zhangjiakou hydrogen energy industry chain faster and stronger. as * * Level renewable energy demonstration zone, in recent years, Zhangjiakou City has continued to promote projects, focusing on hydrogen production, hydrogen storage, hydrogen transportation, hydrogen fuel cell research and development and production, hydrogen fuel cell vehicle production, etc., to accelerate the layout and development of the entire hydrogen energy industry chain. Yang Jinzhu, Deputy Director of Zhangjiakou Municipal Development and Reform Commission : At present, the overall scale of Zhangjiakou hydrogen energy reaches 2.6 billion yuan. "During the 14th Five-Year Plan period, the cost of hydrogen production from renewable energy water electrolysis in our city will be reduced from 30 yuan per kilogram to 14 yuan. From this point of view, the wind power hydrogen production project has good demonstration and driving significance.
