Top 5 grid energy storage container companies in China

Energy storage is widely used in power system

New energy storage is an important technology and basic equipment for building a new power system. By 2025, new energy storage will be developed in a large-scale way, and by 2030, new energy storage will be developed in a comprehensive market. In China, after a series of energy storage related policies were released, the energy storage industry ushered in a good opportunity for development.

China’s energy storage market will move from the era of 100 MW/MWh to the era of GW/GWh. Large scale and large capacity energy storage will be widely and orderly applied to the generation side, grid side and user side of the new power system.

At present, the energy storage technologies with high technical maturity and wide application are pumped storage and electrochemical energy storage. Electrochemical energy storage mainly uses lithium battery technology, taking into account cost performance, safety, service life, industrial maturity and other factors. Lithium iron phosphate battery is the most suitable battery for energy storage at this stage.

Thermal power energy storage auxiliary frequency modulation has high requirements on the performance of energy storage battery, including high magnification characteristics, high climbing characteristics, fast response capability, strong energy efficiency ratio, high temperature safety and long life of energy storage technology.

Therefore, lithium iron phosphate battery is recommended for thermal power energy storage joint frequency modulation project. From the perspective of user side energy storage application scenario, lithium iron phosphate battery is also recommended according to peak shaving and valley filling, demand response, power supply reliability and other requirements.

However, accidents in energy storage power stations still occur. From 2011 to 2021, there were 32 fire and explosion accidents in energy storage power stations worldwide. Battery fires were mainly caused by battery thermal runaway.

Thermal runaway was mainly caused by battery internal short circuit. The main causes of internal short circuit were mechanical abuse, electrical abuse and heat abuse. The way to deal with heat abuse was to adopt good thermal management design.

Large scale centralized energy storage power stations are mainly used in large new energy power generation systems, such as photovoltaic power stations, wind farms, large industrial parks and industrial and mining enterprises. It is connected to 10KV (35KV) medium and high voltage power grid in the form of centralized energy storage power station above MW level to serve as peak shaving, frequency modulation and reactive power support power station.

On the power generation side, it is conducive to the grid connection of new energy, smooth the output of new energy power stations, and promote the consumption of new energy; On the transmission and distribution side, it can cut peak and fill valley, improve the utilization rate of power equipment, and ensure the power quality.

It is helpful to accelerate the construction of battery storage safety and reliable modern energy storage and transportation network with multiple energy complementarities, external connectivity and internal smoothness. In this article, we will introduce top 5 grid energy storage container companies in China.
