Various forms of energy storage have existed for decades. Why do battery energy storage take the lead?

　　Perhaps the most obvious answer is a drop in cost and an improvement in performance, especially in lithium-ion batteries.

　　There is a lingering obstacle in the promotion of battery energy storage, that is, how to apply it in practice, how to allocate value, and how to compensate suppliers.

　　Many energy storage suppliers focus on high-growth areas such as data centers, and some suppliers see the possibility of using energy storage as part of the microgrid.

　　Climate change and severe snowstorms have led to an urgent demand for microgrid energy storage. Energy storage companies are rebuilding and upgrading the power infrastructure on the Caribbean island that was ravaged by the hurricane.

　　In other places, start-up companies are focusing on the energy storage system supporting residential buildings: integrated solar energy + management system + battery, in order to provide services to the grid or participate in energy transactions.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect replacement for lead-acid batteries, and they are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data center and other industries.

　　No matter what the power source is, the battery energy storage solution can be deployed quickly and accurately positioned, and it can improve the efficiency and resilience of the entire grid.

　　The result is to make the concept of energy storage more fascinating.
