The world's largest green hydrogen project will be put into operation by the end of the year. Chemical synthesis and petroleum refining are the main application scenarios at present.

Recently, the National Development and Reform Commission and other departments have issued policies to accelerate the application of hydrogen energy.

The world's largest green hydrogen project will produce hydrogen by the end of the year, and the scale of the green hydrogen replacement industry can reach 100 billion

At the construction site of the Kuqa photovoltaic green hydrogen project in Xinjiang, the entire photovoltaic project covers an area of ​​more than 9,500 mu, equivalent to the size of more than 900 football fields

The Xinjiang Kuqa Green Hydrogen Demonstration Project will use all renewable energy sources such as photovoltaics and wind power to generate hydrogen, with a hydrogen production scale of 20,000 tons per year.

In the process of hydrogen production, green electricity is transported to the hydrogen production workshop, and hydrogen is obtained by alkaline water electrolysis.

Cao Jie, deputy general manager of Sinopec Tahe Refining and Chemical Company, said that Xinjiang is particularly rich in photovoltaic resources, so it is very suitable to explore new energy solutions for hydrogen here

It is understood that taking Sinopec as an example, in order to achieve carbon emission reduction in the refining process, the amount of hydrogen that can be replaced by green hydrogen is 2.

Ling Yiqun, deputy general manager of Sinopec Group Corporation: We expect that the entire petrochemical industry will be replaced by green hydrogen through green electricity in the future, and the future industry scale will be at least 100 billion

Green hydrogen has broad application prospects in transportation, metallurgy, chemical industry and other fields

At present, there are a lot of renewable energy resources in the western region and the eastern coast.

Experts said that from the perspective of terminal consumption, chemical synthesis and petroleum refining are the main scenarios for the current hydrogen application, and the application in the transportation field is less than 1%, and the future space is broad

Li Bo, an expert from the National Energy Science and Technology Resource Center, said that the application of hydrogen fuel cells in the field of transportation has the greatest advantages of high power and long cruising range

In the just-released "Implementation Plan for Carbon Peaking in the Industrial Sector", it is proposed to promote the development of the whole chain of hydrogen energy production, storage, transportation and sales, encourage hydrogen production from renewable energy, implement the hydrogen metallurgy action plan, etc.

If green hydrogen can be applied on a large scale, the first problem to be solved is cost.

It is reported that the production of green hydrogen by green electricity and the production of hydrogen by electrolysis of water are currently the most mainstream methods, of which the cost of electricity accounts for nearly 70%

Li Bo, an expert from the National Energy Science and Technology Resource Center: When the cost of electricity for wind power and photovoltaics is below 0.

It is understood that the heat of 1 kilogram of hydrogen is equivalent to 4 liters of gasoline.

Dai Jianfeng, deputy chief engineer of the General Electric Power Planning and Design Institute: Green renewable energy will become the most important primary energy in the process of hydrogen production.
