Around 2030, Water Electrolysis Hydrogen Generation will become the main body of effective hydrogen supply.
On June 26, the China Hydrogen Energy Alliance released the White Paper on China’s Hydrogen Energy and Fuel Cell Industry in Weifang, Shandong Province, which was jointly prepared and completed over 8 months by more than 30 domestic hydrogen energy and fuel cell industry backbone enterprises and scientific research institutions, including National Energy Group, Tongji University, Steel Research Group and Weichai Power. According to the white paper, at present, electrolytic hydro-hydrogen technology mainly includes alkaline hydrolytic solution tanks (AEs), proton exchange membrane hydro-hydro-hydro-hydro-solution tanks (PEMs) and solid oxide hydro-hydro-hydro solutions (SOEs). Among them, alkaline electrolytic cell technology is the most mature, low generation costs, the maximum gas generation of a single unit in China is 1000 cubic meters / hour; PEM electrolysis process is simple, high energy efficiency, the maximum gas generation of a single unit in China is 50 cubic meters / hour, but due to the use of precious metal electrocatalysts and other materials, the cost is high; Solid oxide hydropower solution tank uses water vapor electrolysing, works at high temperature and has the highest energy efficiency, but is still in the laboratory research and development stage.
The white paper believes that at present, the domestic hydrogen energy industry is still in the market import stage, in addition to some gas companies, market-oriented hydrogen supply channels are limited. Combined with the generation capacity, economy and carbon emissions of hydrogen in different technical routes, different regions have to choose according to their resource endowments.
The white paper predicts that, overall, China’s hydrogen energy market in the early stages of development (around 2020-2025), the average annual demand for hydrogen is about 22 million tons, as fuel increment is limited, industrial by-generation hydrogen due to low costs, and close to the consumer market, will become an effective hydrogen supply body, some areas can explore the development of renewable energy electrolyte hydrogen project demonstration.
Hydrogen market development in the medium term (around 2030), the average annual demand for hydrogen is about 35 million tons, coal hydrogen with CCS technology, renewable energy electrolytic hydro-hydrogen will become an effective hydrogen supply body, and actively promote biological hydrogen and solar photo-catalytic decomposition of water-based hydrogen and other technology demonstration, hydrogen to achieve long-distance large-scale transport.
Hydrogen energy market development in the long term (around 2050), the average annual demand for hydrogen is about 60 million tons, China’s energy structure from traditional fossil energy-based to renewable energy-based multi-pattern, renewable energy electrolytic hydro-hydrogen will become an effective hydrogen supply body, coal-based hydrogen with CCS technology, biological hydrogen and solar photocatalytic decomposition of water-based hydrogen and other technologies to become an effective complement, the overall hydrogen energy supply is abundant, and can achieve 10 million tons of green hydrogen exports.
Public information shows that the China Hydrogen Energy Alliance, known as China Hydrogen Energy and Fuel Cell Industry Innovation Strategy Alliance, is led by the National Energy Group, jointly launched 17 large enterprises, well-known universities and research institutions in China’s energy generation, equipment manufacturing, transportation, metallurgical materials and other industries.
The main duties of the China Hydrogen Energy Alliance are to study the development model of hydrogen energy and fuel cell industry with Chinese characteristics, to issue regular industrial white papers, and to provide policy advice and intellectual support for the formulation of hydrogen energy and fuel cell development strategies and implementation programs for the country.
At present, Xu Guanhua, former minister of the Ministry of Science and Technology and a member of the Chinese Academy of Sciences, serves as the director of the Strategic Steering Committee of the China Hydrogen Energy Alliance, the former vice president of the Chinese Academy of Engineering and the chinese Academy of Engineering, and the executive vice-chairman of the Strategic Steering Committee, and Ling Wen, a member of the Chinese Academy of Engineering who has been transferred from the general manager of the State Energy Group to the vice-governor of Shandong Province, serves as the chairman of the board of directors of the China Hydrogen Energy Alliance.
