Amid the boom in energy storage construction around the world, utility companies across the United States are increasingly turning to energy storage. Energy storage technology is critical because it converts electricity generated by non-dispatchable sources such as wind and solar into dispatchable energy, thereby improving the reliability of the grid and helping to integrate more renewable energy. Battery storage crisis? In recent years, although the development of the energy storage industry has accelerated, it has not been smooth sailing. A recent explosion at an Arizona Public Service (APS) facility that sent four firefighters to the hospital has raised concerns, although the exact cause of the incident is still under investigation and there is no evidence the battery was at fault. ——Concerns about the safety of large-scale energy storage facilities. Donald Sadoway, a professor at the Massachusetts Institute of Technology and an expert on battery technology, said in an interview with US media: “When you put thousands of these batteries in close proximity, it arises how to manage these things safely. problem." APS has always been in a leading position in the procurement of energy storage. In February, the company announced it would add 850 megawatts of battery storage and at least 100 megawatts of solar power by 2025. Despite the incident at the McMicken power station, the company will continue to implement plans based on a longer-term perspective. "In our view, energy storage, including batteries, is critical to a clean energy future. We will continue our plans to add clean energy projects to our system." "Energy storage is an important part of solving important problems and challenges groundbreaking technology, so we remain committed to our plan." APS spokesperson Lily Quezada said. APS’s view on energy storage coincides with that of my country’s new technology company, Zhongneng Technology (Hangzhou) Co., Ltd. Both of them accurately and clearly understand the role of battery energy storage in future clean energy power generation. play a role that cannot be ignored. The industry is concerned about safety issues. Although it sees the bright future of energy storage, if it wants to develop in a long-term and healthy way, safety issues cannot be ignored. In fact, this is not the first time that APS has had an energy storage facility fire in Arizona. Back in 2012, a fire broke out at a 1.5-megawatt system near Flagstaff, Arizona. Although no one wants to see such a situation, it is undeniable that the experience learned from failure is valuable. During that fire, APS learned several important design lessons, including improved air ventilation between cabinets, a 24/7 monitoring system, and the ability to send remote alarms. Relevant personnel from the company also said that in the five years from the 2012 battery incident to the launch of our next-generation battery system in 2017, battery technology has made significant progress in design and safety standards. The technical lessons learned from this have fueled the battery's development, demonstrating the importance of fully investigating the causes of McMicken's equipment failures, which can help industry players learn and move forward with solutions. Safety is a major concern for industry stakeholders. Industry insiders say the biggest dangers associated with energy storage come from a lack of compliance with best design safety measures and a lack of robust training for emergency responders. Energy storage is safe as long as it is designed and integrated responsibly. The failure analysis of this accident is very important. For the industry, this will help continue to improve related protocols, processes and products. Renewable Energy Generation Earlier this month, the Energy Storage Association launched an initiative to prioritize safety when producing and operating energy storage systems. In addition, Duke Energy, one of the largest power companies in the United States, also plans to install approximately 400 megawatts of battery energy storage equipment in the next 15 years. In order to address safety concerns, the American company with 10 years of experience in operating various types of battery energy storage equipment said it is working with supplier companies to ensure that planned energy storage projects have appropriate emergency response instructions and training on site. Safety is also the purpose of Zhongneng Technology (Hangzhou) Co., Ltd. This emerging lithium battery company has never forgotten the important indicator of safety while focusing on the design and development of energy storage systems. As batteries grow in importance as grid assets in the form of energy storage, their importance in energy storage and transportation increases with the rise of electric vehicles.
