In Handan, Hebei Province, Yunda energy storage equipment production base, outdoor energy storage cabinets that look like refrigerators are being concentrated out of the warehouse, and these "super chargers" use semi-solid electrolyte technology to create a layer of "armor" for the battery to "prevent leakage and heat control".

"The semi-solid outdoor cabinet developed by the team has passed the triple test verification of acupuncture, short circuit and overcharge, and provides a reliable energy storage solution for industrial and commercial scenarios with the 'three no' characteristics of 'no thermal diffusion, no fire and no explosion'." The relevant person in charge of the equipment production base introduced.

國家能源局發佈數據顯示，2024年，新型儲能保持快速發展態勢，裝機規模突破7000萬千瓦。截至2024年底，全國已建成投運新型儲能專案累計裝機規模達7376萬千瓦，同比增長超過130%。平均儲能時長2.3小時，較2023年底增加約0.2小時。

Previously, the Ministry of Industry and Information Technology and other eight departments issued the "Action Plan for the High-quality Development of New Energy Storage Manufacturing Industry", which proposes new energy storage technology innovation actions, encourages the development of diversified new energy storage ontology technologies, supports breakthroughs in efficient integration and intelligent control technologies, and focuses on multi-dimensional safety technologies throughout the life cycle.

In recent years, with the rapid development of new energy sources such as wind and solar energy, the impact of their intermittent and fluctuating properties on power grid security has become more and more prominent. "The energy storage system is like a 'power bank', which can store surplus electric energy and discharge it at peak power consumption, which can not only promote the development and consumption of new energy sources such as wind power and photovoltaics, but also improve the flexibility of the power system by peak regulation and frequency regulation." Sun Chuanwang, a professor at the China Energy Economics Research Center of Xiamen University, said in an interview with reporters.

Sun Chuanwang said that the value significance of the development of new energy storage covers three aspects: energy stability, scientific and technological innovation and industrial development.

First, through the innovative self-balancing algorithm and intelligent load response architecture, the dynamic coupling relationship between energy supply and demand is optimized, and the resilience and regulation ability of the new power system are significantly improved.

Second, with its characteristics of long energy storage cycle, high conversion efficiency, and low carbon emissions, it can effectively drive technological innovation and research and development capabilities such as grid connection of China's new energy industry in the process of iteration and application.

The third is to give full play to its advantages of high economic added value and long industrial chain, help give birth to new business formats such as energy sharing, create new economic growth points, and drive the coordinated upgrading of the industrial chain.

發展新型儲能，技術創新是關鍵。鋰離子電池儲能單站規模不斷提高，300兆瓦等級壓縮空氣儲能、100兆瓦等級液流電池儲能、十兆瓦級飛輪儲能專案陸續併網運行，重力儲能、液態空氣儲能、超級電容器儲能等新技術加速落地……我國新型儲能技術不斷取得創新突破。

At the same time of technological breakthroughs, the industrialization development system also needs to be further improved. Accelerate the transformation of science and technology, so that the new quality of productivity to release the momentum of development.

"The industrialization of energy storage should solve the problem of 'how to sell electricity', and the power trading system is the profit center of energy storage projects and the core technology platform to support the operation of the modern power market." According to the relevant person in charge of Yunda Intelligent Storage, the team realizes the optimal allocation of power resources and the efficient operation of the market through digital means.

"Based on cloud computing, big data and artificial intelligence technology, the integration of multi-dimensional data such as weather, load, price, etc., can complete market forecasting and trading strategy optimization, automate transaction settlement and financial reconciliation, reduce labor costs by more than 30%, so as to provide full-process power trading services for power generation enterprises, power grid companies, electricity sales entities and energy storage operators." The above-mentioned person in charge said.

In the future, how to give full play to the "use" of new energy storage and promote the steady and far-reaching development of China's new energy industry?

Sun Chuanwang believes that it is necessary to develop new energy storage with the trinity architecture of "power supply side-grid side-user side", and promote the in-depth evolution of energy production, transmission and consumption patterns to high efficiency, low carbon and intelligence.

"On the power supply side, it is necessary to use the energy storage system as the 'stabilizer' of large-scale grid connection of renewable energy, and greatly improve the controllability and predictability of the output power of new energy stations by virtue of millisecond-level real-time response to peak regulation and valley filling; The combination of intelligent buildings realizes the aggregation of flexible resources on the load side, and promotes the transformation of the terminal energy consumption mode from 'passive consumption' to 'active participation'. Sun Chuanwang suggested.
