Energy storage batteries, mostly lithium-ion batteries, are the core component of energy storage systems. Energy storage batteries serve a wider purpose than power batteries. They are not limited to serving as power wall batteries alone, but are also capable of peak shaving and valley filling, system frequency conversion. Their multi-functional nature has led to their widespread use in regulating and facilitating the output of new energy in power generation, transmission, distribution, and electricity consumption.
Benefiting from the continuous decrease in battery costs and the stimulation of government policies, China's energy storage battery will achieve a newly installed capacity of 5.8 GWh in 2021 on the basis of the 0.3 GWh newly installed capacity in 2017. Under the background of national energy transformation and carbon neutrality strategy, energy storage batteries are an important part of power system reform and new energy power construction. It is expected that the newly installed capacity will reach 6.5 GWh by 2022. Therefore, this article will discuss the top 5 energy storage battery companies in 2022.
Tesla
Tesla is the largest electric vehicle and solar panel company in the United States. It collaborates with Panasonic in battery operations, producing and selling electric vehicles, onboard computers (FSD systems), solar panels, and storage equipment and system solutions. Tesla is the world's earliest producer of autonomous driving cars and the first company to use lithium-ion batteries in electric vehicles. By 2018, Tesla had become the world's best-selling electric vehicle company. In October 2021, it became the sixth giant company to surpass a market value of $1 trillion.
On March 29th, it was reported that American electric car manufacturer Tesla is planning to deploy a large-scale energy storage project called Megapack near its super factory in Texas to avoid the impact of local power grid failures on factory operations. In addition, Tesla's Texas super factory is also installing a large number of solar panels, attempting to use solar power generation and energy storage projects to alleviate the problem of unreliable local power supply.
Sonnen GmbH
Sonnen GmbH is an energy storage company based in Germany that was acquired by the oil giant Shell in 2019. They have now launched a new generation of their sonnenCore system which can help households and the power grid to manage peak demand and provide emergency backup power. The sonnenCore has a capacity of 5 kW/10 kWh and is priced at $9500, which is slightly smaller in capacity than the Tesla Powerwall, with a power of 13.5 kWh.
Sonnen GmbH has independently designed the batteries, inverters, and battery management system for their energy storage system. This sacrifice in cost allows Sonnen GmbH to have better control over the design and operation of the system. Sonnen GmbH has chosen to use lithium iron phosphate batteries, which are known for their safety performance and cycle life, compared to the commonly used lithium-ion batteries in the electric vehicle industry. The energy storage system will be installed indoors and used daily to serve the power grid, solar users, and demand response projects. Therefore, the system's cycle life requirements are set to 10 years or 10,000 charge and discharge cycles.
Solar Edge
Founded in 2006, SolarEdge has developed DC optimization inverter solutions that revolutionized the way power is collected and managed in photovoltaic (PV) systems. SolarEdge's intelligent inverter solutions maximize power generation while reducing energy costs, thus increasing investment return.
Since its listing on NASDAQ in 2015, SolarEdge's revenue and gross margin have continued to grow significantly. SolarEdge continues to advance intelligent energy through its diverse range of products that address a wide range of energy sub-sectors, including residential, commercial and large-scale PV, storage and backup solutions, electric vehicle charging, home energy management, grid services and virtual power plants, battery, and uninterrupted power supply (UPS) solutions.
According to reports, electricity from residential solar installations and accompanying SolarEdge battery storage systems can be collected and aggregated by local utilities to support the grid, particularly during periods of high demand.
In addition, the SolarEdge Energy Bank residential battery storage system, launched in October last year, will integrate with SolarEdge's Energy Hub inverter hardware and grid services software, building a cloud-based real-time aggregation control management and distributed energy resource (DER) system, as described by PearlX.
LG
Established in 1958, LG is a global innovator in the technology and consumer electronics fields. With a perfect combination of intelligent technology and fashionable design, as well as a global production and marketing system, LG has become a world leader in the electronics and communication industries. The company's total global sales in 2020 exceeded $56 billion.
LG Electronics is a manufacturer of leading products in the global mobile phone, flat-screen TV, air conditioning, drum washing machine, optical storage, DVD player, and home theater systems markets.
On February 17th, LG New Energy announced that the company has officially acquired NEC Corporation in Japan. NEC Energy Solutions (NEC ES), a US-based energy storage system manufacturer, has a 100% stake and will enter the energy storage system integration market with a new company called LG New Energy Vertech.
BYD
BYD is a high-tech enterprise dedicated to "using technological innovation to meet people's aspirations for a better life." Founded in February 1995, BYD has developed rapidly for more than 20 years and now has more than 30 industrial base parks worldwide, with strategic layouts in six continents.
BYD's business covers electronics, automobiles, new energy, and rail transportation, and plays a pivotal role in these fields. It builds a comprehensive zero-emission new energy solution from energy acquisition, storage, to application. BYD is a listed company in Hong Kong and Shenzhen, with a turnover and market capitalization of over 100 billion yuan.
On April 6th, BYD stated during research and development that it has invested in BMS-active energy storage systems to meet energy storage, peak shaving, valley filling, frequency regulation, and other service requirements, providing efficient and clean new energy solutions.
