How does renewable energy+energy storage develop?In this forum, the guests set off a "brainstorm"

A week ago, affected by superimposed factors such as high temperature weather and the sharp increase in electricity load, Sichuan initiated the first emergency response of the first -level energy supply guarantee of emergencies in Sichuan. One week later, Sichuan Deyang, an expert, scholar and business personnel from all over the country, still hotly discussed the topic of Sichuan energy insurance. They focused on focusing on the field of energy storage.

On the afternoon of August 27th, as one of the important activities of the 2022 World Clean Energy Equipment Conference, the theme of innovative application and demonstration promotion of the theme of "Renewable Energy+Energy Storage" was held. What opportunities and challenges do new energy storage with new energy characteristics facing new energy characteristics? How to innovate energy storage technology and model and cultivate the energy storage industry? A "brainstorm" was set off at the scene.

Energy storage ushered in the development of "fast lanes"

There are still "troubles of growth" in the industry

"Since the beginning of this summer, many regions in my country have continued to have high temperature and break through the historical peak, which has driven a significant increase in electricity load. The situation of power shortage in some areas has made us realize that it is crucial to continuously improve the ability of energy storage technology. From another side, let us see that the two can have a combined advantage and combined needs. This mode can effectively solve the application scenarios of the power supply side, the power grid side, and the user side. It is difficult to eliminate difficulties, dispatch difficulties, and regulation difficulties to enhance the flexibility of the power system. "As soon as the forum opened, Yao Zhenzhi, deputy director of the Equipment Industry Development Center of the Ministry of Industry and Information Technology, threw out the recent public opinion topic of power. Essence

In Yao Zhenzhi, with the continuous increase in power generation and installation of renewable energy in my country, the "renewable energy+energy storage model" will play an increasingly important role in the adjustment and guarantee of the power system.

On the one hand, the existing energy field is affected by extreme weather. On the other hand, under the national "dual carbon" goal, the energy storage technology and energy storage industry based on the energy reserve level ushered in multiple policies. The "Fourteenth Five -Year Plan" New Energy Storage Development Implementation Plan issued earlier this year clearly clarifies the "roadmap" of the development of the energy storage industry.

However, there are still some difficulties in the energy storage industry that need to be solved.

"From the perspective of energy storage technology categories, it mainly includes physical energy storage represented by pumping energy and compressed air energy storage; electromagnetic energy storage represented by superconducting energy storage and supercapacitance energy storage; The electrochemical energy storage represented by acid batteries. "Hu Bo, deputy secretary -general of the China Smart Energy Industry Alliance, introduced that my country's new energy storage industry is in the early stage of transition from R & D, demonstration to commercialization. Essence

"There are four problems such as high costs, insufficient innovation, large stress, and incomplete mechanisms." Hu Bo analyzed, taking the mechanism level as an example, there are problems such as unclear energy storage market entities and incomplete market operating mechanisms.

"The energy storage industry still has problems such as value embodiment, technical and engineering dilemma, and hidden safety hazards." The problem mentioned by Zhang Fan, the Minister of Science and Technology Innovation of China Electric Equipment Group Corporation, also resonated with participants.

What are the innovative technology?

The industry needs multiple thrusts to be bigger

The "top -level design" of the national energy storage industry proposes a clear goal. By 2025, the new type of energy storage will enter the stage of large -scale commercialization from the initial stage of commercialization into the large -scale commercialization of large -scale commercialization. In the forum, participants generally believe that expanding the application of scenes has become a way for the energy storage industry to move towards large -scale commercialization.

Some new energy storage scenarios are being built. On August 26, Dongfang Electric Group Dongfang Steam Workers Co., Ltd.'s factory area, the world's first carbon dioxide+flywheel energy storage demonstration project was tried in Deyang.

"Carbon dioxide energy storage has the characteristics of high energy density, large capacity, long energy storage time, and no dependence on the project construction. At present, the electric-electric conversion efficiency is 60%-70%." Fang Yu said that renewable energy has intermittent, unstable, and direct power -connected grid to the grid. Therefore, there is a phenomenon of abandoning wind and abandoning light, and energy storage can make interruption, unstable, uncontrollable renewable energy sources Power generation storage, and then released according to demand and controlled control.

Fang Yu also introduced an energy storage mode -shared energy storage power stations. This type of scenario integrates the energy storage resources and needs of the power grid, power supply side, and user -side side. Through large -scale procurement and construction, the cost and operating risks of energy storage power stations are reduced.

A set of data shared on the forum shows that the size of new power storage markets mainly based on electrochemical energy storage and mechanical energy storage in 2025 will exceed 30GW, and the average annual compound growth rate will be more than 50%.

In Hubo's view, the development of the energy storage industry can use the industrial alliance to play the advantages of industry integration and promote the development of the industry. "Through the industry alliance model, the environment and business model that is suitable for the healthy development of the energy storage industry can be explored. Enterprises jointly build energy storage projects to implement landing platforms to promote cooperation. "

As far as Sichuan is concerned, the development of the local energy storage industry is gathering the power of professional scientific research institutes.Lei Xianzhang, the chief scientist of Southwest Petroleum University Carbon Zhonghe and Dean of Tianfu New Energy Research Institute, said in the forum that the achievement of dual carbon targets will face many disruptive technologies challenges.Zero -carbon technology, clean thermal energy and geothermal, new energy storage technology and other future industrial track core technology.Red Star News reporter Ye Yan Song Jia asked
