Top 10 news of the international energy storage industry in 2021

　　In 2021, although the epidemic is still ongoing and the global economy is not optimistic, the energy storage industry is booming. SES Power has nearly 20 years of customized lithium battery product services and customized home energy storage systems. The end application scenario of a considerable share of the product is energy storage. Recently, the media selected the ten most-viewed news reports in the energy storage industry in 2021, which are:

　　1. The world's largest battery energy storage system is officially connected to the grid

　　U.S. retail power and generation company Vistra Energy and its project partners have brought the first phase of the Moss Landing energy storage project online by the end of 2020. The scale of energy storage is 300MW/1200MWh, and it was officially connected to the grid at the beginning of the year. The second phase of the project was completed in the third quarter of this year, and Vistra Energy said that the project will eventually be expanded to 1500MW/6000MWh if market and economic conditions support it.

　　2. LG Energy Solution locks in 6-year long-term supply guarantee

　　The media considers the biggest supply chain event of the year to be LG Energy Solution's signing of a six-year off-take agreement with start-up Sigma Lithium. Shawn Shaw, supply chain expert at Clean Energy Associates, believes the deal is significant not only because LG ES is locking in long-term supply security, but also because Sigma is defining its business model through its sustainability aspects.

　　3. Honeywell Says Flow Batteries Can Meet Utilities' "Core Need" for Long-Term Energy Storage

　　Honeywell launched a flow battery product in October, but the chemistry of the electrolyte remains undisclosed. The industry's focus will be on how the competitive dynamics of recent launches from big names like Honeywell and Lockheed Martin will compete with smaller but more established names in the flow battery space, such as Invinity and ESS Inc.

　　4. With SPAC mergers and stock exchange listings, Stem's road to profitability is difficult

　　Ahead of Stem's NYSE listing, we took a closer look at the California company's disclosures to the U.S. Securities and Exchange Commission (SEC), detailing the risks and rewards of scaling up with Fast Track. How Stem and other newly public energy storage companies play out could also be the big event in 2022.

　　5. Australia is about to make 'massive' electricity market rule changes for batteries

　　Australia's National Electricity Market (NEM), which covers much of the country's wholesale electricity market, has introduced a number of rule changes during 2021.

　　NEM introduced the Five-Minute Settlement (5MS), replacing the 30-minute wholesale electricity spot market settlement rules that have been in place since 1998. At the moment, the impact of this rule change has not really been seen, and early indications are of mixed results, but it is certain that the introduction of this mechanism is welcome in Australia's clean energy sector.

　　6. The world's largest battery energy storage power station overheating incident began to investigate

　　A tough test for the world's largest battery storage project in Moss Landing, California, which was only expanded to 400MW/1600MWh a month or two ago.

　　In the first phase of the 300MW/1200MWh project, some battery modules overheated. The safety feature kicks in after temperatures above operating standards are detected in a few modules. Although some projects have been taken offline for careful implementation, the incident shows that close monitoring and early intervention can prevent the situation from escalating. SES Power believes that, as an industry with only more than ten years of development, battery energy storage is likely to encounter some technical difficulties. How the industry responds and implements best practices will become its main focus in the future.

　　7. Stem became the first listed smart energy storage company

　　Stem, the “AI-powered” smart energy storage company, one of the pioneers in the U.S. commercial and industrial (C&I) space, had its peak in April. As with other SPAC mergers this year and last, financial disclosures before and after Stem's IPO suggest that many companies are walking a tightrope: The battle to become profitable going forward will be intense, but the rewards could be huge.

　　8. ESS Inc becomes the first publicly traded long-term energy storage company in the United States

　　ESS Inc, headquartered in Oregon, USA, is a supplier of flow battery systems based on iron and brine electrolytes.

　　ESS Inc, which said it uses an abundance of non-toxic materials as a competitive advantage, completed a business combination with ACON S2 Acquisition Corp in October and listed on the New York Stock Exchange, becoming the first publicly traded long-duration energy storage company in the United States. Competitor EOS Energy Enterprises hit the market in November 2020, but EOS's battery is technically a 3-hour device that stacks to over 12 hours, while ESS Inc's flow battery is instantly scalable to longer duration.

　　9. The world's largest photovoltaic + energy storage project unveiled in Florida

　　The 409MW / 900MWh solar energy storage project deployed by Florida Power & Light was officially launched at the Manatee Energy Storage Center. The energy storage system will be used in conjunction with the center's existing 75MW photovoltaic power station to store the electricity generated by the photovoltaic power station. The project was developed by NextEra, which completed the construction of the battery project from February to early December this year.

　　10. The global energy storage market size will exceed TWh in 2030

　　By 2030, the deployment of new energy storage will reach 345GW/999GWh, and the investment will be 262 billion US dollars. By then, the cumulative installed capacity of energy storage will reach 358GW/1028GWh. Although some industry insiders said that the forecast value is conservative, because some new application scenarios of energy storage are not considered, such as lithium iron phosphate batteries replacing lead-acid batteries in an all-round way, especially starting batteries. According to market demand, SES Power has launched lead-acid replacement products, such as 12V100Ah, 12V200Ah, 24V100Ah, 24V200Ah, 36V100Ah, 48V50Ah, 48V100Ah, etc., which use square aluminum-shell lithium iron phosphate batteries, such as 12V30Ah, 12V30Ah, 48V100Ah, etc. 12V50Ah car starter battery (maximum peak current up to 1500A). At the same time, we take advantage of the price advantage of echelon batteries, so that SES Power's energy storage system can meet the needs of customers who are picky about prices on the basis of guaranteed performance.
