Recently, state media have focused their reports on a new trillion-class market-energy storage.
For example, in Zhengzhou, which was hit by torrential rains, many citizens' mobile phones could not be recharged and lost contact with their families due to network and power outages caused by floods. Under urgent circumstances, a number of Zhengzhou BYD owners used the vehicle's "mobile power station" function to charge neighbors' mobile phones, portable battery, lamps and other devices.
BYD new energy vehicles act as "mobile power stations" and receive widespread attention, in the area of energy storage. The so-called energy storage mainly refers to the storage of electric energy, energy storage equipment can also be understood as a large portable battery.
According to the report, in Beijing's largest production base of energy storage equipment, energy storage cabinets are the basic unit of energy storage equipment. It is understood that an energy storage cabinet has a daily storage capacity of 5500 kilowatt-hours, such as a large portable battery, which is equivalent to the daily electricity consumption of more than 500 households.
Mo Yuwei, head of production of an energy storage equipment enterprise in Beijing, told reporters: "We now have three production bases, Beijing, Xiangyang and Jinan." At present, the production lines of these three bases have been fully booked by the end of the year, and we are also actively expanding production. "
And the person in charge of the energy storage base said that driven by the new energy storage policy, their orders have increased rapidly recently, and the overall production capacity is expected to increase more than fivefold by the end of the third quarter compared with the same period last year.
Lu Zhe, technical director of an energy storage equipment enterprise in Beijing, pointed out: "compared with the original, the overall market size may have 4 to 6 times growth." In terms of the entire industry chain, the upstream lithium battery products may have a relatively tight production capacity. "
Chen Haisheng, chairman of the energy storage professional committee of the China Energy Research Association, said, "the development cost of energy storage is now declining at a rate of 10 to 15 percent every year with the progress of technology and the rapid development of industrial scale." the size of the market should be more than 500 billion, or even trillions, per year around 2030. "
According to incomplete statistics, the installed scale of new energy storage in China exceeded 10GW in the first half of 2021, an increase of more than 600% over the same period last year. And the number of large-scale projects reached 34, 8.5 times that of last year, radiating 12 provinces across the country.
This is the rapidly developing energy storage market.
Global development of energy storage market
In the United States, Tesla reached a partnership with Pacific Gas and Power in 2019 to deploy several giant battery storage devices called Megapack in the Moslanding community in Monterey Bay, California.
The device's energy storage capacity is so powerful that each giant battery pack can store 3 megawatts of energy a year and can connect enough battery packs together to produce a super energy storage device that stores more energy than the 1GWh, which will provide "six hours of electricity for every home in San Francisco."
It is understood that Tesla recently submitted an application to the Texas Public Utilities Commission in the hope of selling electricity to users.
Recently, a report from the US Energy Information Administration shows that large-scale battery capacity in the United States has tripled in the past five years. American utilities plan to install large-scale batteries with more than 10,000 megawatts of capacity over the next two years, with the new battery capacity 10 times that of 2019.
In addition, South Korea, India and Japan in the Asia-Pacific region are also major markets.
General layout of lithium power enterprises
When it comes to lithium power enterprises, what we have to say is the Ningde era. According to the Ningde Times semi-annual report, in the first half of 2021, the operating income of its energy storage system was 4.693 billion yuan, ranking behind the power battery system (revenue 30.451 billion yuan) and lithium battery materials (revenue 4.986 billion yuan). However, the energy storage system in Ningde era has the highest gross profit margin and the strongest revenue growth.
On August 31, Ningde Times and Jingke Energy signed a strategic cooperation agreement in Ningde, Fujian Province. According to the agreement, Ningde Times and Jingke Energy will be in energy storage business, promoting comprehensive optical storage solutions throughout the county, optical storage cooperation in the global market, carbon neutralization in the upper and lower reaches of the industrial chain, joint research and development based on innovative optical storage architecture and system integration solutions and other areas have reached a comprehensive strategic cooperation intention.
This is the latest development in the field of energy storage in the Ningde era.
It is worth noting that on July 29, Ningde era officially released the first generation of sodium-ion batteries, and the lithium-sodium mixed battery pack was also unveiled for the first time at the press conference.
The target market for sodium batteries is energy storage.
In fact, Ningde Times is not the first brand to mass-produce sodium ion batteries. As early as 2019, Hainna of China Science and Technology, relying on the Institute of Physics of the Chinese Academy of Sciences, established the first sodium ion battery energy storage power station, and achieved mass production in September 2020, with a capacity of 300000 units per month. This is the first company in the world to announce mass production of sodium batteries.
In response to a question from investors on August 23, Shandong Zhanggu said, "Sodium ion batteries are only used as a supplement to the low temperature of some lithium ion batteries, and sodium ion batteries are produced in the same line with lithium ion batteries, so sodium ion batteries are produced only under customer-customized conditions." The lithium / sodium ion battery production line is already ready for mass production. "
For its part, BYD unveiled its new Electroweb energy storage product BYD Cube at the 14th SNEC 2020 held from August 8 to 10, 2020. It is understood that, BYD Cube covers an area of only 16.66m2 and has an energy storage capacity of 2.8MWh. compared with the 40-foot standard integrated energy storage system in the industry, the energy density per unit area of the product has increased by more than 90%, and it is the first to support 1300V DC voltage and match different brands of high-voltage converters.
BYD's energy storage business is mainly concentrated in overseas markets. In Germany, for example, BYD's market share is as high as 19%, second only to German battery maker Sonnen's 20%.
Not only that, it is understood that BYD's blade batteries will be used in energy storage products in the future.
Now, BYD is in the process of expanding production, as evidenced by the fact that it is constantly becoming a new battery company. With the expansion of production capacity, the large-scale supply of blade batteries and their application in the field of energy storage are getting closer and closer.
In terms of Yiwei lithium energy, in early August, Yiwei Lithium Energy announced that it would join hands with Jingmen High-tech Zone to build 30GWh energy storage and power battery projects, specifically the 15GWh logistics vehicle and household energy storage lithium iron phosphate battery project and the 15GWh passenger car ternary battery project.
On June 10, Yiwei Lithium Energy announced that Yiwei Power, a subsidiary, intends to sign a "joint venture agreement" with Lin Yang Energy, and the two sides will invest in a new joint venture company to invest no more than 3 billion yuan in the construction of an energy storage battery project with an annual production capacity of 10GWh.
This is the embodiment that Yiwei lithium can accelerate the layout of the energy storage market.
Guoxuan Hi-Tech entered the field of energy storage even earlier. For example, in response to questions from investors on August 18, the company said, "the layout of the company's energy storage business is relatively early, and in September 2016, the company formally established the energy storage department to enter the energy storage field." In recent years, the company's energy storage business has developed rapidly, and has energy storage projects and related business cooperation with Huawei, Iron Tower, China Power Investment, Electronic 11th Institute, Shanghai Electric, National Electroweb, Jiyuan Software, Xu Ji Group and other companies and units. "
On July 27, Guoxuan Hi-Tech signed a strategic cooperation agreement with Jingke Energy even earlier than in the Ningde era. According to the agreement, the two sides will jointly carry out cooperative R & D, production and sales of the "photovoltaic + energy storage" system. In the fields of product development and production of "photovoltaic + energy storage", development and sales of distributed optical storage systems, one-stop comprehensive solutions, photovoltaic charging equipment, and optical storage and whole county promotion, we will carry out innovative and multi-dimensional strategic cooperation to jointly promote in-depth cooperation of "photovoltaic + energy storage".
It has been revealed that at present, the two sides have carried out preliminary cooperation in the fields of industrial energy storage in the United States and household energy storage in Japan, and the cooperation is based on a good foundation.
In addition, including Xinwanda, Penghui Energy, Xiongtao shares, Bic, Lishen, Ruipu Energy and other battery companies are all in a large-scale layout of energy storage field.
Summary
In July this year, the National Development and Reform Commission and the Energy Administration issued the guidance on accelerating the Development of New types of Energy Storage, proposing to persist in the diversification of energy storage technologies and achieve the initial stage of commercial development of long-term energy storage technologies such as vanadium batteries.
In fact, including sodium-sulfur energy storage monomer battery, hydrogen energy storage and other technologies have been applied in the field of energy storage.
Of course, at present, lithium batteries have the highest comprehensive performance-to-price ratio for energy storage, especially lithium iron phosphate batteries.
The situation of letting a hundred flowers blossom in the field of energy storage is speeding up.
