Hydrogen Energy Industry Chain Overview

Hydrogen industry chain

Hydrogen energy industry chain mainly includes hydrogen production, hydrogen storage and transportation, hydrogen refueling station, hydrogen energy application and other links. Hydrogen production is the starting point of the entire industry chain, hydrogen storage and transportation is the key link to achieve large-scale application of hydrogen energy, hydrogen refueling station is the core hub connecting the upstream and downstream industry chain, and hydrogen energy application is an important terminal for the final realization of green energy transformation.

Hydrogen production link

At present, the main methods of hydrogen production in industrial production are hydrogen production by natural gas reforming and hydrogen production by water electrolysis. Among them, the hydrogen production technology of natural gas reforming is mature and has high economic benefits, but it produces large carbon emissions. Hydrogen production by water electrolysis has the advantage of zero carbon emission, but the cost of electricity is high. In the future, hydrogen production from renewable energy will become an important trend of development.

Hydrogen storage and transportation link

Hydrogen storage and transportation is the key link to realize the large-scale application of hydrogen energy. At present, high pressure gaseous hydrogen storage and transportation is the most widely used storage and transportation mode, which has the advantages of low cost, high safety and wide application range. Liquid storage and transportation of hydrogen has the advantages of high density, easy storage and convenient transportation, but it needs to solve the security and economic problems of low temperature liquid storage and transportation technology. Solid-state hydrogen storage and transportation has the advantages of high safety and low cost, but it needs to solve the decomposition and resynthesis of solid-state hydrides during storage and transportation.

Hydrogenation station link

Hydrogenation station is the core hub connecting the upstream and downstream industry chain, and is an important infrastructure to realize hydrogen energy application. At present, the construction cost of hydrogen refueling stations is high, but with technological progress and scale expansion, its cost is expected to gradually reduce. The construction of hydrogen refueling station needs to comprehensively consider urban planning, safety protection, environmental protection and other factors, and it is necessary to solve the manufacturing of hydrogen refueling equipment, the localization of hydrogen refueling equipment, and the location layout of hydrogen refueling station.

Hydrogen energy application link

The application of hydrogen energy is an important terminal for the final realization of green energy transformation. At present, the application of hydrogen energy in transportation, electric power, industry and other fields has been widely concerned. In the future, with the expansion of technological progress and market size, the alternative role of hydrogen energy in the field of transportation will be more significant, and it will also be expanded to energy heating, industrial production, aerospace and other fields.

Hydrogen energy future outlook

Hydrogen energy industry chain has a large output value

According to the China Hydrogen Energy Alliance is expected, by 2025, China's hydrogen energy industry output value will reach 1 trillion yuan; By 2050, the demand for hydrogen will be close to 60 million tons, hydrogen energy will account for more than 10% of China's terminal energy system, and the annual output value of the industrial chain will reach 12 trillion yuan, becoming a new growth pole leading economic development.

Developing new models of hydrogen production

At present, China's hydrogen production link is still "gray hydrogen", "blue hydrogen", the national energy Group, the State power investment and many other power generation enterprises and new energy enterprises layout "wind, light, storage, hydrogen" integration project, to achieve an integrated coupling, wind and light with hydrogen, hydrogen to promote scenery, production and finance combination of deep coordination. Green hydrogen replacing gray hydrogen will become the development trend of hydrogen energy industry in China and the world.

Hydrogen refueling stations become new infrastructure

The construction and operation of hydrogen refueling station is an important part of hydrogen energy industry, and also a key factor restricting the development of hydrogen energy industry. With the strong support of national policies and the positive response of local governments and enterprises, the construction and operation of hydrogen refueling stations will usher in new development opportunities and become an important part of the new infrastructure.

Hydrogen storage and transportation

It is expected that in the future, the transportation of hydrogen in China will be mainly based on the high-pressure gaseous long tube trailer, supplemented by pipeline transportation, and actively develop storage and transportation methods such as solid state, cryothermia and high pressure, and organic liquid, to form a high-density, lightweight, low-cost, and diversified hydrogen energy storage and transportation system.

Applications of hydrogen energy

At present, hydrogen energy is mainly used in the field of transportation, and in the future, hydrogen energy will be widely used in energy heating, industrial production, aerospace and other fields.

It is believed that in the future, hydrogen energy will closely cooperate with traditional energy and other new energy sources, complement each other, and jointly constitute the main force of China's terminal energy consumption, and play an indispensable role in promoting green energy transformation and achieving sustainable development.
