The development of “green hydrogen” has become a consensus

At Baofeng Energy’s photovoltaic hydrogen production plant, large gas storage tanks marked “Green Hydrogen H2″ and “Green Oxygen O2″ stand in the sun. In the workshop, multiple hydrogen separators and hydrogen purification devices are arranged in an orderly manner. Pieces of photovoltaic power generation panels are embedded in the wilderness.

Wang Jirong, head of Baofeng Energy’s hydrogen energy project, told the China Securities Journal that a 200,000 kilowatt photovoltaic power generation device is composed of a piece of photovoltaic power generation panels, plus an electrolyzed water hydrogen production device with a capacity of 20,000 standard cubic meters of hydrogen per hour. Feng Energy Hydrogen Energy Industry Project.

“Using the electricity generated by photovoltaics as power, the electrolyzer is used to produce’green hydrogen’ and’green oxygen’, which enter Baofeng Energy’s olefin production system to replace coal in the past. The comprehensive manufacturing cost of’green hydrogen’ is only 0.7 yuan/ Wang Jirong predicts that 30 electrolyzers will be put into operation before the end of the project. After all are put into operation, they can produce 240 million standard squares of “green hydrogen” and 120 million standard squares of “green oxygen” annually, reducing coal resource consumption by approximately 38 per year. 10,000 tons, reducing carbon dioxide emissions by about 660,000 tons. In the future, the company will comprehensively develop in the direction of hydrogen production and storage, hydrogen storage and transportation, and hydrogen refueling station construction, and expand application scenarios through collaboration with urban hydrogen energy demonstration bus lines to realize the integration of the entire hydrogen energy industry chain.

“Green Hydrogen” refers to hydrogen produced by the electrolysis of water with electricity converted from renewable energy. Water electrolysis technology mainly includes alkaline water electrolysis technology, proton exchange membrane (PEM) water electrolysis technology and solid oxide electrolysis cell technology.

In March this year, Longi and Zhuque invested in a joint venture to establish a hydrogen energy company. Li Zhenguo, president of Longji, told a reporter from China Securities News that the development of “green hydrogen” needs to start from reducing the cost of electrolyzed water production equipment and photovoltaic power generation. At the same time, the efficiency of the electrolyzer is improved and the power consumption is reduced. Longji’s “photovoltaic + hydrogen production” model chooses alkaline water electrolysis as its development direction.

“From the perspective of equipment manufacturing costs, platinum, iridium and other precious metals are used as electrode materials for proton exchange membrane electrolysis of water. The equipment manufacturing costs remain high. However, alkaline water electrolysis uses nickel as electrode material, which greatly reduces the cost and can meet the needs of future electrolysis of water. The large-scale demand of the hydrogen market.” Li Zhenguo said that in the past 10 years, the manufacturing cost of alkaline water electrolysis equipment has been reduced by 60%. In the future, technology and production assembly process upgrades can further reduce equipment manufacturing costs.

In terms of reducing the cost of photovoltaic power generation, Li Zhenguo believes that it mainly includes two parts: reducing system costs and increasing life cycle power generation. “In areas with more than 1,500 hours of sunshine throughout the year, Longi’s photovoltaic power generation cost can technically reach 0.1 yuan/kWh.”
