The proportion of green energy will climb, and the global grid energy storage system

In order to make up for the shortcomings of green energy intermittent green power such as solar photovoltaic and wind energy, Battery Energy Storage System (BESS) is used to improve energy efficiency. As the proportion of green energy increases, the global grid energy storage system in 2022 The equipment will increase from 3.8GW in 2017 to 23.4GW.

According to the latest report from GlobalData, the five major players behind the rapid development of energy storage technology are the United States, South Korea, China, Japan and Australia. The equipment of the five countries accounted for 80% of the world in 2017, and the United States accounted for 28% of the largest. The Asia-Pacific region is the world leader with a 54.1% ratio, followed by the Americas with 32.8% and the Europe, Middle East and Africa (EMEA) with 13.1%. Lithium-ion batteries have always been the first choice for energy storage technology. In 2017, BESS accounted for more than 75%.

Global regional situation

In the Asian market, South Korea is the leader in 2017, accounting for 31.3%. And because South Korea will spend $35.7 billion to develop green energy plans in the next five years, including incentives such as solar energy storage equipment, it is expected that South Korea's BESS will grow substantially in the future.

The United States accounts for 87.4% of the market in the Americas, of which California has the largest installed capacity of energy storage equipment. In 2015, the Aliso Canyon natural gas storage event in Los Angeles promoted California's energy storage construction and project development, and in 2016, the equipment exceeded 200MW.

Germany is the country with the highest energy storage capacity in the EMEA region, accounting for 44.8%. Its energy storage technology is mostly used to assist the grid and solar energy storage technology. In the future, with the KfW Development Bank's energy storage subsidy and the country's fixed electricity price mechanism (FiT) rate decline. The energy storage market will further expand. At present, the proportion of renewable energy generation in Germany is rising, and the demand for grid balance is increasing day by day. Some independent energy storage system projects have been started or put online.

At the same time, Europe is also working to establish a battery storage system industry chain, and the EU battery industry is also turning its development to low-carbon energy. In contrast, Africa, the Middle East and Central and South America have only a little energy storage plan, and hope that the future renewable energy growth and growth will drive the market, and it is expected that solar energy storage will create the largest market for BESS in the future.

BESS future and challenges

In the future, the proportion of renewable energy power generation will continue to rise. In order to make electricity more flexible and flexible, the demand for BESS technology will also increase, and energy storage can also reduce the total electricity bill. If you do not want frequent power outages, the development of energy storage technology is also a Good choice.

In addition, special markets such as telecommunications and data centers will also increase the demand for battery energy storage, hoping to improve performance and propose better solutions through energy storage.

However, the development of BESS will not be smooth. There is no general development law or standard on the energy storage equipment. Therefore, each manufacturer has its own internal standards, which leads to installation and maintenance compatibility problems, which may delay the scale of the energy storage system. Economic Effects. If we can formulate relevant regulations and strengthen energy storage penetration and improve stability and reliability, it will be beneficial to the development of electricity and energy storage in various countries.

And because BESS lacks reliability and security issues, energy storage systems have always been difficult to finance, so money, lack of common mechanisms, policy factors and ownership of energy storage systems may be the obstacles to the rapid development of BESS.
