May 29th, 2024: China State Council issued the "2024-2025 Energy Conservation and Carbon Reduction Action Plan." The plan sets the following energy conservation and carbon reduction goals:

 

In 2024, the energy consumption and carbon dioxide emissions per unit of GDP will be reduced by approximately 2.5% and 3.9%, respectively.

The energy consumption per unit of industrial added value in enterprises above a designated size will be reduced by about 3.5%, and the proportion of non-fossil energy consumption will reach about 18.9%.

The energy-saving and carbon-reduction transformation in key fields and industries will achieve an energy-saving of approximately 50 million tons of standard coal and a reduction of carbon dioxide emissions by about 130 million tons.

By 2025, the proportion of non-fossil energy consumption will reach about 20%, with energy-saving and carbon-reduction transformation in key fields and industries achieving the same energy-saving and carbon reduction goals, making every effort to achieve the binding targets set for energy conservation and carbon reduction during the 14th Five-Year Plan period.

 

Hydrogen energy will play a significant role in this energy conservation and carbon reduction action, mainly reflected in the development of non-fossil energy, hydrogen metallurgy, and hydrogen chemical industry.

 

Strengthening the development of non-fossil energy: Accelerating the construction of large-scale wind and photovoltaic bases in deserts, Gobi, and wastelands. Rational and orderly development of offshore wind power, promoting the large-scale development and utilization of ocean energy, and pushing for the development and utilization of distributed renewable energy. Orderly construction of large-scale hydropower bases, active and safe development of nuclear power, and localized development of biomass energy, while coordinating the promotion of hydrogen energy development. By the end of 2025, the proportion of non-fossil energy power generation will reach about 39%.

 

Accelerating energy conservation and carbon reduction transformation in the steel industry: Promoting the comprehensive utilization of blast furnace top gas, coke oven gas waste heat, and low-grade waste heat. Advancing the integration of processes such as hot metal ladle transportation and hot slab direct rolling. Strengthening the demonstration and application of low-carbon smelting technologies such as hydrogen metallurgy. By the end of 2025, the proportion of production capacity in the steel industry reaching benchmark energy efficiency levels will be 30%, with capacities below the benchmark level undergoing technological transformation or being phased out. Over 80% of the national steel production capacity will complete ultra-low emission transformation. Compared to 2023, the comprehensive energy consumption per ton of steel will be reduced by about 2%, and the self-generated power rate from waste heat, pressure, and energy will increase by more than 3 percentage points. In 2024-2025, the steel industry's energy conservation and carbon reduction transformation will achieve an energy-saving of about 20 million tons of standard coal and a reduction of carbon dioxide emissions by about 53 million tons.

 

Promoting the reengineering of petrochemical and chemical processes: Accelerating the promotion of advanced technologies such as the new generation of ion membrane electrolyzers. Vigorously advancing the substitution of renewable energy, encouraging the research and application of renewable energy hydrogen production technologies, supporting the construction of green hydrogen refining projects, and gradually reducing the amount of coal-based hydrogen in the industry. Orderly promoting the transition from steam-driven to electric-driven processes and encouraging large petrochemical and chemical parks to explore the use of nuclear energy for steam and heat supply.

 

Technologically, the current hydrogen production from water electrolysis is well-developed, including mainstream methods such as alkaline water electrolysis (ALK), proton exchange membrane (PEM) water electrolysis, and high-temperature solid oxide water electrolysis (SOEC). Among these, ALK occupies more than 95% of domestic green hydrogen projects due to its technological maturity. The "ion membrane electrolyzer" mentioned in the plan uses a cation exchange membrane as a diaphragm to provide lower resistance and higher current efficiency, making the electrolysis process more efficient with lower energy consumption. As the technology matures, it is expected to further expand its market space in the future.
