"In the first half of this year, equity financing in the hydrogen energy industry continued the hot trend since last year. A total of 21 financing events occurred, with a financing amount of 1.59 billion yuan. The number and amount of financing increased by 50% and 137% respectively over the same period last year. Investment in the hydrogen energy industry is characterized by earlier investment rounds, more concentrated investment areas and the distribution of the whole industrial chain of popular racetracks." Kang Yong, chief economist of KPMG China, said at the 2022 China International Trade in services Fair. This is a microcosm of the current rising heat of China's hydrogen energy industry and the fast track of development. According to insiders, the hydrogen energy industry chain has initially taken shape. Under the influence of multiple favorable factors such as policy support, active participation of enterprises and favor of capital, hydrogen energy is expected to take the lead in realizing commercialization in the field of transportation. At the hydrogen energy economic development forum held on September 3, Han Wei, Executive Deputy Secretary General of China hydrogen energy alliance, introduced that hydrogen energy has been officially incorporated into China's energy strategy system, five ministries and commissions have approved five fuel cell vehicle demonstration cities, and many provinces have issued special policies on hydrogen energy. The application of hydrogen energy is unfolding, and the industry is entering a new stage of development. It is understood that the hydrogen energy industry chain mainly includes upstream hydrogen production, midstream hydrogen storage and transportation, hydrogen refueling stations, and downstream diversified application scenarios. At the hydrogen production end, electrolytic water hydrogen production is the most promising green hydrogen energy production mode. In particular, electrolytic water hydrogen production using renewable energy is the technology path with the lowest carbon emission among many hydrogen source schemes. Electricity price and electrolytic cell cost are the key to realize large-scale production of green hydrogen. High pressure gaseous hydrogen storage and low temperature liquid hydrogen storage have entered the commercial application stage, while organic liquid hydrogen storage and solid material hydrogen storage are still in the technical research and development stage. At present, the main application scenarios of hydrogen energy are concentrated in the fields of transportation, industry, power generation and construction. Among them, transportation and industry are the main application fields, and construction, power generation and heating are still in the exploration stage. Data show that by the end of 2021, China had achieved a hydrogen production capacity of about 40 million tons / year, an output of about 33 million tons / year, and 8939 hydrogen fuel cell vehicles. By the end of June this year, more than 270 hydrogen refueling stations had been built in China, ranking first in the world. Lin Zhongqin, academician of the Chinese Academy of engineering, deputy secretary of the Party committee and President of Shanghai Jiaotong University, predicted that under the premise of reaching the peak carbon by 2030, China's annual demand for hydrogen would exceed 37 million tons, accounting for 5% of the terminal energy consumption. Under the background of carbon neutrality in 2060, China's annual demand for hydrogen will reach 130 million tons, accounting for 20% of the terminal energy consumption, 60% in the industrial field, 32% in the transportation field, and 8% in other fields. "In this process, fuel cells are expected to become an important breakthrough." Lin Zhongqin believes that there are currently three models that can accelerate the commercialization of fuel cell heavy trucks. The first is the subsidy model of the national demonstration city cluster, the second is the subsidy model of wind and power resources, and the third is the pure commercial model of low-cost hydrogen. It is hoped that the price of fuel cell vehicles will be equivalent to that of diesel vehicles by 2025. KPMG's research results also show that under the influence of multiple favorable factors such as policy support, active participation of enterprises and favor of capital, the development of hydrogen energy industry
