Carbon neutral consumption ratio of fossil energy and non-fossil energy

At present, the consumption ratio of fossil energy is about 80%, and that of non-fossil energy is less than 20%.

In recent years, the proportion of coal in China's energy consumption structure has gradually decreased, but the absolute value is still high. On the whole, the consumption ratio of fossil energy is about 80%, while the consumption ratio of non-fossil energy is less than 20%. In the future, this structure will undergo subversive changes. Under the background of carbon neutrality, the proportion of non-fossil energy will reach more than 80%.

Such a change obviously needs the support of revolutionary technology. In Xu Chunming's view, this mainly involves two aspects: first, the treatment and utilization of carbon dioxide, including the use of physical methods, such as underground storage and carbon dioxide displacement; Or use chemical means to convert carbon dioxide into high-value chemicals and materials through polymerization, synthetic reaction, hydrogenation, etc.

Secondly, the reduction of carbon dioxide emission intensity, that is, although energy is consumed, carbon dioxide is not emitted as much as possible, which mainly depends on the application of green electricity and green hydrogen.

Increase the proportion of non-fossil energy sources

On March 23, 2023, China General Nuclear Power Group Delingha 2,000 kW photothermal storage integration project was held. The project adopts renewable energy power generation technology combining photovoltaic power generation and photo-thermal molten salt energy storage, and realizes high-proportion storage of molten salt heat energy through tower-type concentrated heat collection and utilization of wind and light in the region.

The high-temperature steam generated by the brine heat exchanger drives the steam turbine generator set to generate electricity, and the annual on-grid electricity can reach 3.65 billion kWh after it is completed and put into operation. This is the epitome of the rapid development of clean energy in China.

In view of the green and low-carbon development of energy, the planning has rationally decomposed and refined the development indicators, and put forward a series of target indicators such as the proportion of non-fossil energy consumption, the proportion of non-fossil energy power generation, the proportion of electric energy in terminal energy consumption, and the installed scale of hydropower and nuclear power in the Tenth Five-Year Plan.
