![[Viewpoint] Energy storage initially has an industrial basis](http://i.bosscdn.com/blog/lazy.gif)
Multiple difficulties to overcome
The key factor for the rapid development of the energy storage industry is that the National 5 Departments jointly issued the “Guiding Opinions†in 2017. This is China’s first national-level energy storage industry policy, which has enabled the storage energy to obtain a “quasi-identity cardâ€.
"The role of "Guidance Opinions" is mainly four clear." Qi Zhixin, director of the Department of Science and Technology Equipment of the National Energy Administration, pointed out that "the policy orientation that encourages the support of energy storage development is clarified; the identity of the main body of energy storage is clarified; Investment management mechanism; clarified the task of energy storage demonstration."
Despite the significance, the reporter learned that the "Guidance Opinion" in the industry seems "not quenching thirst", because this is only a directional, guiding programmatic document, and there is no specific implementation rules.
According to Shi Yubo, executive vice president of China Energy Research Association, although energy storage initially has an industrialization foundation, there are still many problems in China's energy storage industry development that need to be overcome and resolved.
"First, the energy storage policy system needs to be further improved. It is necessary to further refine the industrial policies to help the development of the energy storage market and promote the commercialization of energy storage. Second, the multiple value gains of energy storage are still unclear. It is necessary to clarify the storage and storage of energy storage. The application value of distribution and use of each link needs to reflect the commercialization value of energy storage through open electricity market and flexible market price mechanism. Third, energy storage technology innovation needs further breakthrough. Energy storage technology safety, stability, The improvement of efficiency still needs to seek breakthroughs in R&D and market inspection. Fourth, the management process of energy storage projects needs to be further clarified. It is necessary to standardize and supervise all aspects of filing, approval, supervision and management to ensure the rational and legal construction of energy storage projects. ."
New energy + energy storage space is vast
The reporter learned from the Zhongguancun Energy Storage Industry Technology Alliance that by the end of 2017, the cumulative installed capacity of China's investment and energy storage projects was 28.9 GW, of which the cumulative installed capacity of electrochemical energy storage projects reached 389.8 MW. It is not difficult to see that the scale of energy storage installed is relatively small compared to the entire power installation. In the industry's view, this is the opportunity for energy storage development, and its future development space is worth looking forward to.
“With the development of new energy, the application space of energy storage will be greatly expanded.†Li Weichun, general manager of solar energy and fuel cell technology services in Greater China, TÜV Rheinland Group, believes that “if we use economic figures and indicators to measure, I There is no doubt that every year is a trillion-dollar market. In addition, the development of electric vehicles will also drive the commercial application of mobile energy storage. These two are already very large markets."
As the cost of new energy continues to decline, the role of new energy, represented by wind power and photovoltaics, in the energy structure continues to increase. Zhao Yongqiang, deputy director of the Renewable Energy Center of the Energy Research Institute of the National Development and Reform Commission, believes that the two trends in the future transformation of the power system will become clearer – renewable energy generation accounts for the increase in the proportion of the entire power system and distributed energy generation accounts for the entire power system. The increase in the proportion.
"With the increase in the proportion of wind power and photovoltaics, how to suppress its volatility and reduce the impact on the power system? Energy storage will effectively solve this problem." Zhao Yongqiang said.
Xia Qing, professor of electrical engineering at Tsinghua University and deputy director of the Energy Storage Committee of the China Energy Research Association, said that the development of clean and low-carbon energy has become the strongest voice of the times. The fourth industrial revolution will be the large-scale use of new energy, and new energy. And energy storage is a twin sister, accompanied by each other.
“The largest energy storage market, the most important application is in new energy. With the increase of the proportion of new energy power generation, such as optical storage, wind storage and distributed energy storage will become the development direction.†Vice President of Sunshine Power Optical Storage Division The appearance of the family said in an interview with the reporter.
Give full play to the value of energy storage
The role of current energy storage is gradually becoming prominent, especially the capacity value, energy value and auxiliary service value played in the electricity market cannot be underestimated, but unfortunately, the value of energy storage has been neglected for a long time, and it has not been obtained at the price. reflect.
According to Jiang Liping, deputy dean of the State Grid Energy Research Institute, there is no need to introduce special policies for the value of energy storage, but to establish a new ecosystem based on the entire system that can reflect the value of various main technologies. "With such a system, energy storage must have its living space, and it must be a very good living space." She believes that "as long as our electricity market system or management rules can truly reflect the commodity attributes, form a reasonable power product. In the market segment, the space for energy storage will be huge."
The current high energy storage power cost limits the application space of energy storage to a certain extent, but in many industry's view, the cost of energy storage is not high. "Comparative to the cost of social governance such as pollution caused by thermal power, from the value of energy storage and the cost of energy storage can reduce the cost of replacement of capacity, etc., the cost of energy storage is not high. Complex problems are simplified, it is recommended at the top of energy storage. In the design and system, renewable energy is installed in a certain proportion of energy storage, that is, the quota system, to achieve a large proportion of renewable energy online, while improving grid friendliness and reducing investment in power grid auxiliary service facilities." Wu Jiamorph believes that “In the energy storage cost of renewable energy development and national energy strategy, the energy storage value will be fully reflected, and the energy storage industry will also develop rapidly.â€
It is the common expectation of the industry to let power return to commodity attributes and fully reflect the value of energy storage. To this end, Shi Yubo proposed to accelerate the process of energy storage to participate in the marketization of electricity. "Accelerate the construction of auxiliary services in various regions and localities, pilot and demonstrate the construction of joint and independent energy storage power stations in areas with relatively perfect market rules, explore the commercialization value of energy storage and improve market rules, and build an effect-based payment mechanism for energy storage participation system services; Accelerate the pace of construction of the spot market, pilot market-based transactions involving energy storage systems, assess project operational risks under flexible electricity market prices, and build power demand side management, especially demand response long-term mechanisms, to encourage grid companies to actively fulfill their social responsibilities and The necessary incentives will be given in the verification of transmission and distribution prices to create a new platform for energy storage to gain value."
Liu Yafang also said that in the next step, the National Energy Administration will work with relevant departments to break down the policy barriers for energy storage access. According to the spirit and progress of the power system reform, market-oriented, reduce the attributes of energy commodities, and establish and improve the energy storage market. The institutional mechanism of value.
