At 12:00 noon last Friday, a fire broke out at the PV-ESS-charing Integrated Energy Storage Power Station located at the Dahongmen Jimei in Beijing's South Fourth Ring Road. While dealing with the fire, the power station in its northern area suddenly exploded without warning, resulting in the sacrifice of two firefighters, the loss of another staff member and the injury of one firefighter. The cause of the fire is still under investigation.
The project is the Beijing Fuweisi 25MWh energy storage station put into operation in March 2019, equipped with 25MWh Gotion’s LFP batteries and photovoltaic, fast charging and other equipment, had been the world's largest user-side energy storage facilities, with huge economic and social benefits.
As we all know, lithium battery products have certain safety risks, any improper use, product defects, poor installation and design, etc. may cause its thermal spread, thermal runaway eventually lead to fire, explosion, etc.. The construction of energy storage plants should be equipped with safety equipment as required, especially in terms of management systems to prevent cell failure and loss of control as well as monitoring systems. In the event of an unavoidable fire, automatic fire-fighting facilities inside the power plant should also be activated in time to avoid further spread of fire.
The fire can be said to have pushed the electrochemical energy storage technology into the limelight. For how to avoid the recurrence of such events, perhaps the industry is currently looking forward to a mandatory national standard to regulate the design, construction, operation and maintenance of energy storage power plants. At the same time, we also hope that all manufacturers, design companies, power plant operation and maintenance companies can implement the concept of safety in depth, to avoid energy storage, a very important technology in the energy transformation, being challenged in the early stages of development.
