Energy storage has a strong momentum of development and may usher in a golden age of development.  At the second China Energy Storage Technology and Application Exhibition held recently in Shenzhen, a number of listed companies including BYD, Xiongtao Co., Ltd., Kelu Electronics, Nandu Power Supply, Mengshi Technology, Xinwanda, Yiwei Lithium Energy, Dazu Laser and san yang shares all brought new products to the exhibition.
While enterprises and capital are aiming at energy storage outlets, the energy storage industry as a whole still needs to explode.  Chen Zhicheng, deputy general manager of Sunlight Power Energy Storage Division, said bluntly that China's energy storage market has not yet developed and is limited to sporadic demonstration projects and small-scale applications invested by enterprises themselves.  "China started slowly, and it is predicted that the Chinese market will not enter the stage of rapid growth until 2019."  Chen zhi said.
On October 11, the "Guiding Opinions on Promoting Energy Storage Technology and Industrial Development" (hereinafter referred to as "Guiding Opinions") posted on the official website of the National Development and Reform Commission (NDRC) clearly defined for the first time the strategic positioning of energy storage in China's energy industry.  Industry insiders predict that the energy storage industry is expected to erupt in 2017.  This statement is not groundless. From the 13th Five-Year Plan for the development of strategic emerging industries in the country, the 13th Five-Year Plan for the development of renewable energy, the 13th Five-Year Plan for the development of energy, to the 13th Five-Year Plan for the innovation of energy technologies, energy storage is one of the key research and development areas.
Under the background of gradually clear policy support, many enterprises have begun to step up their efforts to expand the energy storage market and further explore profitable business models.


Listed companies have entered the cards one after another.
 

At the 2nd China Energy Storage Technology and Application Exhibition, all listed companies displayed competing product technologies one after another.  As a leading enterprise in the field of new energy storage in China, Kelu Electronics has intensively displayed its core products in the energy storage field, covering grid-level energy and power energy storage systems, household systems, two-way energy storage converters, all-in-one optical storage machines, mobile energy storage vehicles, cloud platforms of energy storage power stations and energy management systems.
Yinlong New Energy, which has attracted a lot of attention because of Dong Mingzhu's stake in the company, will display its main products such as lithium titanate battery modules and container-type energy storage power stations.  Esotel, which specializes in photovoltaic business, mainly displays the company's energy storage converter, container energy storage power station, intelligent AC power distribution cabinet, energy storage and smart microgrid system solutions, etc.
The reporter's on-site visit found that chemical energy storage using various batteries as energy storage medium is currently the mainstream of various companies' products.  Chen zhi, deputy general manager of the solar power energy storage division, said there was no doubt that lithium batteries led the way in the global energy storage market.  As of the first quarter of this year, in the U.S. market, lithium batteries account for 97% of nearly 300 MWH of energy storage.
At the level of listed companies, Wind statistics show that there are 17 listed companies in the field of energy storage equipment. according to incomplete statistics, there are 26 listed companies involved in the energy storage market. among them, a number of enterprises such as Nandu power supply, BYD, kelu electronics, xiongtao co., ltd. and mengshi technology have stepped up their distribution in the field of energy storage.
Specifically, Nandu Power Supply has expanded the "investment+operation" energy storage system commercialization mode since 2016.  In January this year, Nandu Energy and Zhejiang Branch of China Construction Bank signed a strategic cooperation agreement for the energy storage power station fund, with a total fund size of 5 billion yuan for the first phase.  Subsequently, Nandu Power Supply and Zhongheng Electric (Consortium) won the bid for the energy storage and standby power supply project of China Mobile Data Center, with a total capacity of 121.7MWh.
As the largest supplier of lithium-ion battery composite materials in China, Shanshan Co., Ltd. also announced earlier that it plans to invest 5 billion yuan in the industrialization project of Shanshan Energy Management Service within 3 years. The main content is to formulate and implement the optimized comprehensive solution of "energy storage and power saving", "photovoltaic power generation" or "combination of light and storage" according to the comprehensive power demand of industrial and commercial enterprise users.  Among them, the funds planned to be invested in the energy storage management service project will focus on the promotion of energy storage and energy saving services for peak cutting and valley leveling, with a planned construction scale of about 2GWH and a corresponding investment scale of about 3.8 billion yuan.
In addition, Kelu Electronics, a leading enterprise in the field of new energy storage, entered the field of new energy storage as early as 2009.  BYD, a leading new energy vehicle company, has been "ploughing deep" into overseas energy storage markets. Its energy storage products have made continuous sales in the United States, Japan, Australia, South Africa and other markets.  When Sunrise Technology took the lead in developing multi-component materials for energy storage, it has been applied to Tesla's energy storage projects and other high-end energy storage markets in large quantities by large international customers.  Xiongtao Co., Ltd. owns sharp container energy storage equipment, household photovoltaic energy storage system of Mengshi Technology, mobile portable energy storage system and other products.
Yinlong New Energy is also constantly working in the field of energy storage. Yao Gaoliang, president of the company's energy storage research institute, told the Securities Times that at present Yinlong New Energy has completed a number of energy storage technical standards and demonstration projects, including the joint formulation of the national energy storage battery standards in cooperation with China Southern Power Grid, the demonstration project of Shenzhen Baoqing Energy Storage Power Station, and the Zhangbei Wind Energy Storage Demonstration Project in cooperation with China National Power Grid.  Yinlong New Energy has the basis of industrialization in the basic definition and direction of energy storage development.


What is the market capacity?

The Guiding Opinions put forward that the related work will be carried out in two stages in the next 10 years. The first stage will realize the transition from research and development demonstration to the initial stage of commercialization of energy storage.  In the second stage, the initial stage of commercialization will be transformed into large-scale development.
What is the capacity of the domestic energy storage market?  Liuyong, Secretary General of the Energy Storage Application Branch of the China Chemical and Physical Power Industry Association, said that by the end of June this year, 1.4GW of electrochemical energy storage had been installed and put into operation in China, 10 times the cumulative installed capacity from 2000 to 2015.  In particular, the attention of all kinds of social capital has entered the stage of distribution.  "The official promulgation of the guidelines for the national energy storage industry has added great impetus to the final' one kilometer' break in the development of the energy storage industry."  Liuyong said.
In recent years, China's energy storage projects have entered a stage of rapid development.  Every year, the newly-added installed capacity and the accumulated installed capacity show a rising trend.  Energy storage projects account for 56% of distributed power generation and micro-grid, more than half of the national energy storage projects. Renewable energy grid-connected applications account for 35%, ranking second.
Energy storage is naturally linked to new energy power generation projects such as wind and light.  Societe Generale Securities pointed out that due to the intermittence and instability of new energy sources such as wind and light, the power generated by renewable energy sources is difficult to be stable and the power supply stability of its power system cannot be guaranteed. The application of energy storage systems to wind power and photovoltaic power generation can greatly change this disadvantage.  The introduction of energy storage system can provide a certain buffer for the connection of new energy to the power grid, and play a role in stabilizing fluctuations, cutting peaks and filling valleys and energy dispatching.
From a global perspective, energy storage has entered a rapid growth stage since 2008, with the installed capacity increasing at a rate of about 20% per year.  Since 2013, with the rapid growth of distributed photovoltaic installed capacity and the acceleration of power system reform since the second half of 2015, the electricity price mechanism in some regions has become more flexible. The user side can obtain immediate and obvious economic benefits by using energy storage. The installed capacity of energy storage on the user side has increased rapidly.
Xiexin integration related staff told reporters: "the introduction of the" guidance "is to further promote the industrialization of energy storage, but due to the energy storage industry related subsidies have not been able to fall to the ground, energy storage equipment costs remain high, commercialization is still some time away.  Judging from the current development trend of renewable energy in China, the explosion of energy storage market is not far from us. "
In terms of specific application fields, energy storage is currently the main market for applications among FM and industrial and commercial users.  "There is a slight feeling that projects with business models, such as Shanxi's energy storage service market, can recover their costs in 3 to 4 years.  In industrial and commercial consumer-side energy storage markets in Beijing, Shanghai, Jiangsu, Shenzhen and other places, lead-acid battery energy storage systems can recover costs in about 6 to 8 years, while lithium battery energy storage takes 8 to 10 years. "  Liuyong said that the long return period on investment is a difficult problem for the energy storage industry to attract customers.


Star products are in short supply.

The market exists, but how to develop it is the focus of the industry.
Chen zhi believes that the development of energy storage industry depends on many aspects, first of all, the maturity and advancement of technology.  The second is the birth of the business model.  The business model is related to the cost of the whole energy storage system.  "Based on the battery system (lithium battery) we currently use, the cost of the entire energy storage system and the cost per unit of electricity are 0.61 yuan."
In fact, based on the rapid development of chemical energy storage technology in recent years, the cost of chemical energy storage has been continuously reduced. Energy storage economy provides a prerequisite for the further commercial application and promotion of chemical energy storage.  Chen zhi said that with the development of battery technology, the cost of energy storage has dropped very fast in the past few years, but with the large-scale use of batteries in electric vehicles, this year is likely to enter a turning point period, and the cost of energy storage will tend to decline slowly in the future.  "Especially this year, when the global supply of positive electrode materials and battery raw materials is tight, the price of batteries will rise."  Chen zhi said.
Although most listed companies have early card placement, the lack of star products still plunges the market into a scuffle.  "At present, there are many well-known projects in the domestic energy storage industry. They are operating outside the public's vision.  Baoqing Power Station of China Southern Power Grid has been in operation for 6 years, and the market seldom knows its operation data.  Zhangbei Energy Storage Base is the world's largest demonstration base for centralized combination of various energy storage and new energy power generation. Unfortunately, it is difficult to find matching pictures on the Internet. "  Ye Jianfei, deputy chief engineer of Zhongtian Energy Storage Technology Co., Ltd., pointed out that star products are needed to make the market believe in the technology of energy storage industry in order to realize gear shifting acceleration.
For example, Ford Model T, which was born in 1908, Apple's smartphone iPhone, and Tesla's electric car.  "When everyone defines the electric car as the second car in the family, and its range is defined as less than 200 kilometers, Tesla will introduce the electric car, which runs 400 kilometers and has other performance comparable to that of traditional fuel-fired cars, as a star product."
Ye Jianfei believed that the emergence of star products announced that the dispute over the technical route had come to an end and the production process and system were complete.  Product positioning and market demand find a fit point.  At present, the whole energy storage industry still lacks star projects to lead the industry, to prove that the technical level of the energy storage industry meets the market demand.
In addition, although photovoltaic wind power has a natural connection with the energy storage industry, the development of energy storage still cannot keep pace with the photovoltaic industry in sturm und drang.  Relevant statistics show that by the end of 2015, China's cumulative installed capacity of photovoltaic power generation has reached 43.18 million kilowatts, becoming the country with the largest installed capacity of photovoltaic power generation in the world.  By the end of 2016, China's newly added and accumulated photovoltaic installed capacity has reached the first in the world.  However, in recent years, the scale of new wind power and photovoltaic installations in China is far larger than that of new energy storage projects. In the future development, only by implementing large-scale energy storage projects and keeping pace with the construction of wind power and photovoltaic power can the energy storage industry be further developed.
