my country has become the world's largest hydrogen producer with an annual output of 33 million tons

"China is already the world's largest hydrogen producer, with a hydrogen production capacity of about 40 million tons per year and an output of about 33 million tons per year
.
" Wang Xiang, deputy director of the High Technology Department of the National Development and Reform Commission, revealed at the press conference today
.

In recent years, China's hydrogen energy industry infrastructure has developed rapidly, but compared with the international advanced level, there is still a certain gap
.

In terms of hydrogen production, although China is already the largest hydrogen producer in the world, "it is mainly composed of hydrogen production from fossil energy and industrial by-product hydrogen.
Coal hydrogen production and natural gas hydrogen production account for nearly 80%, chlor-alkali, coke oven gas, Industrial by-product hydrogen such as propane dehydrogenation accounts for about 20%, and the scale of hydrogen production from renewable energy is still very small
.
” Wang Xiang said, “In the past two years, although the volume of hydrogen production from renewable energy is not large, the development trend is relatively positive.
"
.

It is understood that Zhangjiakou Renewable Energy Demonstration Zone was established in 2015.
Relying on abundant wind power and photovoltaic resources, a number of wind and solar hydrogen production projects have been constructed to provide green and low-carbon hydrogen energy for the operation of fuel cell buses for the Winter Olympics; Ningxia relies on abundant wind power and photovoltaic resources.
Photovoltaic resources, build Ningdong photovoltaic hydrogen production and other projects, and provide green low-carbon hydrogen energy for coal chemical projects
.

Today, the National Development and Reform Commission and the National Energy Administration jointly released the "Medium and Long-Term Plan for the Development of Hydrogen Energy Industry (2021-2035)", proposing that by 2025, hydrogen production from renewable energy will become an important part of new hydrogen energy consumption; by 2030, A relatively complete clean energy hydrogen production and application system will be formed; in 2035, the proportion of renewable energy hydrogen production in terminal energy consumption will increase significantly
.

In terms of hydrogen storage and transportation, according to statistics, China's current stage is mainly based on high-pressure gaseous long-tube trailer transportation, and pipeline transportation is still a weak point
.
According to Wang Xiang, the hydrogen storage pressure of the high-pressure gaseous long-tube trailer is 20MPa, and the single-vehicle carrying capacity is about 300 kilograms of hydrogen.
The technology and equipment manufacturing are relatively mature
.
"Liquid storage and transportation and solid-state storage and transportation are both in the small-scale laboratory stage
.
" In terms of pipeline hydrogen transportation, China's current hydrogen pipeline mileage is about 400 kilometers, and the pipeline in use is only about 100 kilometers
.

In terms of hydrogen refueling, China has built more than 200 hydrogen refueling stations, but mainly 35MPa gaseous hydrogenation stations, 70MPa high-pressure gaseous hydrogenation stations account for a small proportion, and the construction of liquid hydrogen hydrogenation stations and hydrogen production and hydrogenation integrated stations and lack of operational experience
.
In addition, the daily refueling capacity of existing hydrogen refueling stations in China is mainly distributed in the range of 500-1000 kg, and large-scale hydrogen refueling stations larger than 1,000 kg still need to be further constructed and laid out
.

Wang Xiang said frankly that infrastructure construction is an important guarantee for the development of the hydrogen energy industry.
The National Development and Reform Commission will continue to promote the construction of domestic hydrogen energy infrastructure and accelerate the construction of a safe, stable and efficient hydrogen energy supply network
.

In terms of storage and transportation system, it emphasizes the principle of safety and controllability, supports the exploration and practice of various storage and transportation methods, and gradually builds a high-density, lightweight, low-cost, and diversified hydrogen energy storage and transportation system
.
Explore the application of storage and transportation methods such as solid state, cryogenic high pressure, and organic liquid, and carry out pilot demonstrations such as hydrogen-doped natural gas pipelines and pure hydrogen pipelines
.

In terms of hydrogenation network, the principle of demand orientation is emphasized
.
On the premise of ensuring safety, the land resources shall be used sparingly and intensively, supporting the use of existing gas station facilities in accordance with laws and regulations to renovate and expand gas stations, and exploring hydrogen refueling stations that integrate hydrogen production, hydrogen storage and hydrogen refueling stations in the station, etc.
