"Breathing air, adding hydrogen, and emitting water." Hydrogen energy is considered the "best energy of the 21st century" and seems to be the "best solution" to solve the global energy crisis. However, it cannot be ignored that the bottlenecks in hydrogen storage technology and hydrogen fuel cell technology limit the widespread use of hydrogen energy. For mega cities like Guangzhou, the development of hydrogen energy is not only necessary for industrial restructuring, but also plays a crucial role in the sustainable development of the city. On December 6th, at the 2nd Guangdong Hong Kong Macao Greater Bay Area (Guangzhou) Hydrogen Energy Industry Conference and the 1st Guangzhou New Energy Storage Industry Conference, Guangzhou announced a series of new actions to promote the development of the hydrogen energy industry, including the city's first hydrogen fuel cell industry innovation consortium launching the first domestically produced hydrogen fuel cell system "Navigation One" and hydrogen fuel cell vehicles, Launch the first section of the Beijing Guangzhou Hong Kong Macao Expressway, the Guangdong Jiangxi (Guangzhou Shaoguan Ganzhou) cross provincial hydrogen corridor, and sign contracts for 35 representative enterprise projects. At present, the national "hydrogen energy heat" is rising wave by wave, and Guangzhou is gradually taking a stable and solid "Guangzhou path" in the field of hydrogen energy. What are the mysteries behind building a "hydrogen corridor" across provinces? At the conference, the debut of the first section of the Guangdong Jiangxi (Guangzhou Shaoguan Ganzhou) cross provincial hydrogen corridor on the Beijing Guangzhou Hong Kong Macao Expressway has received particular attention. This corridor has a total length of 428 kilometers, starting from Guangzhou and passing through G4 Beijing Hong Kong Macao Expressway, G6011 Nanshao Expressway, and G45 Daguang Expressway. It passes through Shaoguan and reaches Ganzhou, Jiangxi. Along the way, unloading and energy replenishment are carried out in Shaoguan, making it a demonstration line for inter provincial hydrogen energy heavy-duty truck logistics transportation between Guangdong and Jiangxi. Yang Qiang, General Manager of Guangdong Yuntao Hydrogen Technology Co., Ltd. (hereinafter referred to as "Yuntao Hydrogen"), introduced that the route uses the fuel cell engine system of Guangzhou Hydrogen Fuel Cell Industry Innovation Consortium "Navigation 1" as the power output, and the entire vehicle uses a 49 ton tractor from Dongfeng Liuzhou Automobile Co., Ltd. The hydrogen supply for vehicles is provided by Guangdong Baohydrogen Technology Co., Ltd., Shaoguan Shaobao Logistics Co., Ltd. is responsible for the operation of the Guangzhou Shaoguan section, and Jiangxi Shunzhang Mining Co., Ltd. is responsible for the operation of the Ganzhou Shaoguan section. The goods transported along the entire route are mainly steel and cement, which will fully leverage the advantages of hydrogen energy for "heavy load and long distance". Why is it different to use hydrogen energy to transport goods? Yang Qiang has calculated an account for us. "Taking each car running 500 kilometers back and forth every day as an example. Compared to diesel cars, hydrogen energy can save 50 cents per kilometer, and running for a day can save more than 200 yuan; compared to electric cars, although there is a difference in shipping costs per kilometer, it may require 800 kWh of electricity, so the weight of the battery will reach about 4 tons, limiting the transportation volume of goods. Hydrogen energy only needs 1.3-1.5 tons, which can increase the amount of goods transported and make up for the difference in shipping costs." By doing so, hydrogen powered trucks can travel 500 kilometers per day, reducing a total of 37 million tons of carbon emissions in a year, highlighting their advantages in long-distance heavy-duty transportation. And for the hydrogen supply during transportation, this corridor has also come up with an efficient solution: setting up Shaoguan hydrogen refueling mother station, Lixi hydrogen refueling sub station, and Shixing hydrogen refueling sub station in the form of "sub mother station". The hydrogen gas at the mother station is cheaper, so
