According to the reply, Urad Middle Banner plans to complete the construction of wind power by 2025 3.5 million kilowatts, 300,000 kilowatts of photovoltaics, 380,000 kilowatts of electrochemical energy storage (2 hours), and the proportion of renewable energy power supply in the total energy supply has reached more than 80%.

At the same time, by 2025, the new energy electrolysis chemical industry will build 4 electrolytic hydrogen production stations, with a total hydrogen production scale of 12,240 tons per year (excluding synthetic green ammonia intermediate products), and an integrated synthesis of "green ammonia" with a scale of 750,000 tons /year, the ethanol production scale is 400,000 tons; the production capacity of battery anode materials is 100,000 tons/year.

Key construction content

Shenhua Ba Neng Coal Chemical Expansion Project. The project plans to expand the coking production capacity of 3.6 million tons by Shenhua Baneng on the basis of the 1.2 million tons of coal coking that has been completed, and build three new 1.2 million tons of tamping coke production lines. The height of the carbonization chamber is 6.25 meters, and the total scale reaches 4.8 million tons. Coking new production capacity indicators will be resolved by Shenhua Group's internal coordination or external acquisitions. The project uses coking coal imported from Mongolia as the main raw material, and uses new energy such as clean energy and hydrogen to replace traditional energy for construction. It is an important demonstration of exploring low energy consumption and low emissions in the coking industry.

Copper smelting deep finishing project. Give full play to the advantages of port import resources and local energy, build a resource industry chain, form industrial characteristics that cannot be copied and are difficult to replace, build an industrial chain of copper resource import-smelting-processing-products, and strengthen the mutual advantages of imported mineral resources, energy advantages and industrial advantages Support, establish the integration and symbiotic relationship between the non-ferrous industry and the new energy industry, and create a characteristic, potential, and most profitable non-ferrous metal production and processing base in northern my country. By 2025, the amount of imported copper resources will be increased, and the smelting scale will be formed. The industrial chain has been effectively established and it has become one of the important copper production and processing bases in northern my country.

Huaqi's 100,000-ton battery anode material processing project. The project is to build a new energy battery negative electrode material production project with an annual output of 100,000 tons. The negative electrode material production not only conforms to the development market trend of the new energy industry, but also makes full use of the graphite mineral resources in Urad Zhongqi. It belongs to the upstream and downstream linkage projects. On-site consumption of large-scale new energy power in Wulate Zhongqi.

New energy electrolysis hydrogen production project. New energy hydrogen production technology is to convert wind energy, solar energy, etc. into electrical energy through wind power generators, photovoltaic devices, etc., and convert electrical energy into hydrogen through electrolyzed water hydrogen production equipment. energy transformation. According to different power sources, new energy hydrogen production technology can be divided into two types: grid-connected wind power hydrogen production and off-grid type. Grid-connected new energy hydrogen production is a hydrogen production method that connects wind turbines and photovoltaic modules to the grid and takes electricity from the grid. It is mainly used in large-scale wind power, photovoltaic abandonment, abandonment and energy storage. Off-grid new energy hydrogen production is to provide the electric energy generated by wind farms and photovoltaic power plants directly to electrolytic water hydrogen production equipment for hydrogen production without going through the power grid and self-built transmission and distribution lines and transformer facilities. As a new energy storage method, new energy hydrogen production technology will be more widely used to stabilize the imbalance of large-scale wind farms and photovoltaic power plants, and improve the utilization rate of renewable energy power generation. The new energy hydrogen production technology module includes wind power generation system, photovoltaic power generation system, power grid, electrolysis water hydrogen production system, hydrogen storage system and hydrogen transportation system.

New energy hydrogen production and synthetic ammonia project. Guohua Bayannaoer (Wulate Zhongqi) Wind Power Co., Ltd. plans to invest in the construction of a 300,000-ton/year green hydrogen synthesis ammonia project, and Urumqi Jisheng New Energy Company plans to invest in the construction of a 450,000-ton green hydrogen synthesis ammonia project. The main raw material of the green hydrogen synthesis ammonia project is water. The "green hydrogen" produced by the electrolysis of water from new energy sources is used to further synthesize ammonia. It is an important measure to effectively alleviate the development constraints of "dual control" of park energy consumption and create a "zero-carbon park".

Xiaolong Metallurgical Phase III Project. The project is a 300,000-ton high-carbon ferrochrome alloy phase-3 continuation project of Xiaolong Metallurgy. The third-phase project will build two 33,000KVA fully enclosed ferrochrome submerged arc furnaces, forming a new production capacity of 150,000 tons/year of high-carbon ferrochrome alloy, and Supporting construction of waste heat recovery, gas comprehensive utilization facilities, and corresponding public service auxiliary projects and environmental protection projects.

Coal gangue peaking power plant project. It is estimated that by 2025, Ganqimaodu port will import 30 million tons of coal per year, local washing scale will reach 25 million tons per year, and produce 1.8 million tons of coal gangue per year. Coal slime and coal gangue are used as the main raw materials to build a peak-shaving power plant project. Through the combination of the peak-shaving power plant and the new energy power supply, a more stable new power system in the park is formed. The power generated by the peak-shaving power plant and clean "green electricity" support each other and As a supplement, jointly provide high-quality and low-cost energy supply for enterprises in the park.

"Wind-solar-heat-storage" integrated new energy project. Photothermal power generation has three basic characteristics. One is cleanliness. Photothermal power converts light energy into heat energy, and then converts heat energy into electrical energy, which is a renewable energy source. The second is homogeneity. CSP and thermal power also drive generators through steam turbines, which have high controllability and rotational inertia. The third is adjustability. Solar thermal projects are equipped with more than 10 hours of energy storage, which can provide system operation adjustment for fluctuating new energy sources such as wind power and photovoltaics, promote the stable and controllable power generation output of the system, and improve the regional renewable energy consumption level. In the process of transforming the traditional power system dominated by thermal power to the new power system dominated by new energy, solar thermal can play an important core role due to its high degree of substitution for thermal power.
