What is an energy storage system
Energy storage system, also called energy storage system. This kind of device is like an oversized “charging treasure”, which can store excess thermal energy, kinetic energy, electrical energy, potential energy, chemical energy, etc., change the output capacity of energy, output time at the output location, etc., make rational use of energy and improve energy utilization rate.
In addition to the increasingly mature application of energy storage systems such as wind farms, photovoltaic power plants, and thermal power plants, various power shortages and large power users have become the best places for energy storage technology to be used.
Portable energy storage is growing rapidly, and home energy storage is poised to take off
Mobile energy storage can be divided into three categories according to consumption scenarios
Portable energy storage:
① Outdoor travel scenarios, supply power for mobile phones/computers, etc., to meet the diversified portable needs of outdoor travel; ② In emergency disaster preparedness and other scenarios, in areas prone to earthquakes and tsunamis, a small power generation system can be formed with solar panels to meet the needs of disaster victims electricity demand.
RV energy storage:
The lead-acid battery energy storage system is relatively mature and has been widely used in finished RVs; in recent years, the trend will be to add foldable solar panels for backup power generation.
Home energy storage:
Due to the high price of overseas electricity and the need to improve the stability of the power grid, according to the China Research Institute of Industry Research, the global home energy storage scale in 2020 will be about US$7.5 billion, and it is expected to reach US$26.4 billion by 2027, a cagr20%. OSM battery has obtained the EU CE certification, and the safety of the battery is guaranteed. Currently, their products are sold worldwide.
Home energy storage market:
According to QY Research, the global portable generator market size will be approximately 18.7 billion in 2020, and will reach 30.4 billion by 2026, with a CAGR of 7.2%.
Large overseas space, emergency power generation is difficult
At present, the difficulties for overseas users to use electricity:
Powerwall-10k 48v lithium battery
① Overseas grids are relatively unstable & electricity costs are high, the American Society of Civil Engineers reported that there were more than 3,500 outages in 2015, with an average duration of 49 minutes. ② In order to deal with this problem, at present overseas households are generally equipped with emergency power generation devices, but the disadvantages are high cost, high noise and high pollution. Advantages of home energy storage: stable electricity consumption + low cost, with policy subsidies. The energy storage battery OSM battery company currently provides 5KWH, 10KWH, wall-mounted and stacked styles of energy walls. Such products can address the needs of household energy storage.
Huge space for family development, dominated by lithium-ion batteries:
Ground ECO 2.6kwh Residential BESS
At present, the main development market of home energy storage is Europe, and the basis of home energy storage system is mainly electrochemical energy storage. According to the cumulative data of CNESA in 2018, the user side of electrochemical energy storage dominates, accounting for 32.6%. Electrochemical energy storage will be further divided into lithium-ion batteries and lead-acid batteries, of which lithium-ion batteries dominate; according to CNESA data in 2022, lithium-ion batteries account for 88.8% and lead-acid batteries account for 10%.
According to the prospectus of Paineng Technology, in the global household energy storage shipments in 2019, ternary lithium batteries accounted for 55% (mainly from Tesla and LG Chem), and lithium iron phosphate batteries accounted for 41% (7pct higher than 2018) , and other lithium batteries account for 4%.
For the continued strength of the energy storage sector, the main influencing factors
On the one hand, driven by the goal of “carbon neutrality and carbon peaking”, the proportion of new energy sources such as wind power and photovoltaics in the power supply has increased, and their volatility and intermittency have brought unprecedented demand for energy storage.
Energy shortage in Europe sparks demand for residential energy storage
Since 2022, European energy prices have risen sharply. Due to the soaring energy and electricity prices in Europe, North America and other regions, the household energy storage market has shown an explosive trend in Europe and the United States. In particular, European household energy storage has thriving and leading the world. Most households use 48V energy storage systems, which have 100Ah, 200Ah, and 300Ah to store electricity.
The application of household photovoltaic + energy storage can improve the level of self-generation and self-consumption of electricity, delay and reduce the risk of rising electricity prices, and at the same time obtain stable electricity support, so the demand is rapidly rising.
