We will build a new energy system with energy storage as the core and multiple energy sources complementing each other

Zeng Shaojun introduced that at present, another feature of our country's new energy is distributed. Distributed new energy can provide a strong support for national energy security and extreme conditions. At present, our distributed new energy has risen in the total amount, but the distributed energy quality also needs the technical progress and support of the energy storage system, and it is also necessary to explore miniaturized distributed solar thermal power generation.

"In the first half of this year, our total installed capacity of renewable energy generation has exceeded 1.3 billion kilowatts, accounting for about 48.8% of China's total installed capacity, almost half. But installed capacity is not equal to power generation, wind and solar energy fluctuate, and energy storage technology becomes the technical engine of energy transformation." Zeng Shaojun said.

The report of the Party's 20th National Congress proposed to "accelerate the planning and construction of a new energy system." Accelerating the planning and construction of a new energy system is not only an inherent requirement for actively and steadily promoting carbon peak carbon neutrality, but also an important support for further promoting the energy revolution and promoting high-quality economic development.

Zeng Shaojun believes that the inherent requirements of the new energy system are actually to build a new energy system with energy storage as the core and multi-energy complementary. First of all, energy storage must be the core. Without energy storage as the core, no new energy can independently take on the important task of new energy revolution; Secondly, we must build a new energy system with multiple complementary energies, which is the direction of the future.

To build a new power system, it is necessary to promote the diversified development of new energy storage, promote the development of various forms of energy storage such as thermal energy storage, hydrogen energy storage, and electrochemical energy storage, and support the construction of a multi-energy complementary energy system. It is necessary to adhere to the simultaneous development of centralized and distributed energy storage, actively develop the integration of source, charge, storage and control and multi-energy complementarity, and innovate the energy storage industry model to foster new growth drivers.

Finally, Zeng Shaojun stressed that in the field of new energy, there will be technological upgrading in 3 to 5 years, and there will be big changes in the field of new energy in 5 to 10 years. From a forward-looking point of view, in the next 10 years or even longer, new energy will be developed to perovskite, hydrogen fuel, small nuclear fusion, liquid sunlight and other fields.

Noun interpretation

perovskite: Perovskite solar cells (perovskite solar cells) are solar cells that use perovskite organic metal halide semiconductors as light-absorbing materials, belonging to the third generation of solar cells, also known as new concept solar cells.

Hydrogen fuel: Hydrogen fuel cell is a power generation device that converts the chemical energy of hydrogen and oxygen directly into electrical energy. The basic principle is the reverse reaction of electrolytic water, which supplies hydrogen and oxygen to the anode and cathode respectively, and the hydrogen diffuses outward through the anode and reacts with the electrolyte, releasing electrons to the cathode through the external load.

Small nuclear fusion: The micro nuclear battery (penny-sized nuclear battery) is small, only a coin thick, extremely powerful, very safe to use "nuclear battery". Can be used to charge mobile phones. By using micro - and nanoscale systems, it has developed an ultra-micro power supply device that emits charged particles through the decay of radioactive material to generate a continuous current.

Liquid sunlight: "Liquid Sunshine" (i.e. "clean methanol" and "green methanol") refers to methanol produced with very low or zero carbon emissions during production. "Liquid Sunlight" was named by the Liquid Sunlight Research Group of the Chinese Academy of Sciences, and was publicly published in the international journal Joule in September 2018, and has been unanimously recognized by the international academic community and peers.
