It is reported that in March this year, the National Energy Administration issued the "Guiding Opinions", which for the first time clarified the strategic positioning of energy storage in China's energy industry, proposed the development goals in the area of ​​energy storage in the next 10 years, and emphasized the five major tasks of energy storage. It can be said that from the beginning of the initial stage to the subsequent layout of later stage capital, the development of China's energy storage industry is still out of the real eruption and there is still a lack of “door-to-doorâ€. It is worth looking forward to whether the “Guiding Opinion†can promote industry breakthroughs.
"Fankou period" energy storage industry
Xie Binglin said that the "Guiding Opinions" will play an active role in creating a good policy environment, guiding social capital investment, guiding the demonstration of technological R&D, and promoting the establishment of business models. “The National Energy Administration will continue to promote the introduction of supporting measures, carry out pilot demonstrations, improve the standardization system, establish industry information platforms and other related work, provide effective support for the development of energy storage industries, and create a good atmosphere.â€
According to the “White Paper on Energy Storage Industry Research†published by the relevant agencies, by the end of 2016, the cumulative installed capacity of China's put into operation energy storage projects was 24.3GW, an increase of 4.7% year-on-year. Among them, the cumulative installed capacity of lithium-ion batteries accounted for the largest proportion, 59%, an increase of 78%; the use of molten salt heat storage in the country is still relatively small, only 10MW of molten salt heat storage projects put into operation in Qinghai at the end of last year, This project is also the third large-scale molten salt thermal storage tower type solar thermal power station in the world.
As we all know, energy storage is an indispensable support link for the development of smart grids, renewable energy access, distributed generation, and electric vehicles. With the vigorous development of renewable energy in China, the development of energy storage has increasingly attracted attention of all parties.
According to the “13th Five-Year Plan for Renewable Energy Developmentâ€, photovoltaic power generation will reach 105 million kilowatts by 2020, solar thermal power generation will reach 5 million kilowatts, wind power will reach 210 million kilowatts, and renewable energy power generation capacity will be 680 million kilowatts, with a power generation of 1.9 million. Trillion kWh, accounting for 27% of the total electricity generation.
As a clean, renewable energy source, photovoltaic power generation and wind power are experiencing rapid development, but they also face problems such as wind and light rejection caused by difficulties in connecting to the grid. After more than ten years of R&D and demonstration applications, large-scale energy storage construction has become an important means to solve the problem of renewable energy grid integration.
According to the “White Paper on Energy Storage Industry Research 2017,†the cumulative installed capacity of China's energy storage projects put into operation by the end of 2016 was 24.3GW, a year-on-year increase of 4.7%. In 2016, the installed capacity of newly added electrochemical energy storage projects across the country was 101.4 MW, an increase of 299% from the same period last year. From the perspective of application distribution, the integration of renewable energy sources is still the largest area of ​​application of the newly added electrochemical energy storage projects in China last year, accounting for 55% of the total. The White Paper predicts that by the end of 2020, the cumulative installed capacity of China's electric energy storage and thermal energy storage technologies will reach 44 GW, of which the cumulative installed capacity of electrochemical energy storage technology will reach 2 GW.
The data shows that more than 4 billion U.S. dollars of investment are currently directly invested in the energy storage field, mainly applied to technological research and development or expansion of production. There are also many companies in China that have started to arrange energy storage markets since 2016 and promoted the energy storage industry. The development of the Chinese market.
Industry insiders believe that the “Consultation Opinions†reaffirmed the strategic positioning of energy storage and once again raised its importance, it can be foreseen that supporting policies in the future will be gradually introduced. Judging from the development goals and tasks of energy storage, the industry is still in a period of development and commercialization needs to be accelerated.
Subsidy is an international practice
Researchers told reporters that as a strategic emerging industry, relevant national authorities have formulated relevant incentive policies for energy storage technology development and industrialization, which will guide energy storage related companies to participate more actively in domestic and international power markets. In order to promote the development and improvement of renewable energy, optimize existing power systems, and increase overall energy efficiency, major countries in the world have policies and measures to support the development of energy storage technologies, which generally include tax reduction subsidies, one-time investment subsidies, and participation in commercialization. Electricity price competition, electricity price subsidies and other aspects.
Some experts believe that some of China's existing industrial policies have not yet reached an in-depth, practical operation stage in the promotion of energy storage development. They lack a detailed outline of the facts, such as possible subsidies, preferential policies, accounting, and other relevant measures or implementation measures. .
Also from the results of feedback from companies seeking opinions, the appeals of companies of different natures are not consistent, for example, they hope to reward the energy storage dispatched by the corresponding power demand side, and give 150 to the corresponding time of 24 hours, 4 hours and 30 minutes respectively. RMB/KW, 200 RMB/KW, 300 RMB/KW incentive; some hope that the policy encourages energy storage to be combined with the construction of charging stations for electric vehicles, and the energy storage system combined with charging stations should enjoy the power grid in addition to subsidies for thermal power generation. There is a subsidy of 0.1 yuan/kWh for network fees; there is also a certain percentage of subsidies for construction costs according to the size of the battery capacity.
Zhu Jinping said that from the feedback results, the focus of disputes on energy storage subsidies among various companies is mainly in the form of subsidies. He hoped that various companies could make suggestions and fully discuss the Third Energy Storage Subsidy Policy Consultation Meeting within the year to form effective comprehensive feedback and promote the development of the energy storage industry.
The reporter found that the establishment of domestic energy storage companies mainly presents three characteristics: First, the domestic energy storage companies join hands with leading international battery companies to establish specialized energy storage companies to achieve complementary technologies and market advantages, and vigorously develop domestic energy storage business. Second, traditional photovoltaic companies rely on their advantages in the development and construction of photovoltaic systems and market channels to adapt to market demands, establish specialized energy storage companies, and open up optical storage businesses. Thirdly, battery companies set up specialized energy storage system solution business in the form of setting up branch companies or participating shares, and they are seeking to make breakthroughs in business other than electric vehicles while expanding battery capacity.
For example, in December 2016, five companies and individuals, including Dong Mingzhu and Wanda Group, jointly raised capital by 3 billion yuan and got involved in the Yinlong incident in Zhuhai. The lithium titanate technology held by Yinlong reflects the expectation of companies outside the industry to quickly enter the field of energy storage, especially in the field of new energy vehicles.
A real problem is that the high cost of energy storage construction at the current stage and the poor economic return have become an important factor limiting the further development and promotion of new types of chemical energy storage. Needless to say, the economy is the limiting factor for the further development and application of new energy storage technologies. For the domestic energy storage industry, the lack of market demand has limited equipment manufacturing manufacturing process improvements and technological innovations, while the original product's local stepping leads to high investment costs, which together with low returns constitute a gap that investors can hardly leapfrog. The situation of financing difficulties and expensive financing, in turn, also freezes the rapid development of the market.
At present, the general opinion of the industry is that the continuous development of energy storage technology depends to a large extent on the country’s continuous and clear development strategy. The development of energy storage is closely related to the development of new energy sources. The rapid development of China's energy storage industry and market can not be separated from the support of energy policy support, the completion of electric reform supporting measures, the increase in the proportion of renewable energy installed capacity and power generation, the reduction of energy storage technology costs, and the establishment of a sustainable business model.
