Gas Sensors for Electrochemical Energy Storage Power Stations
The Chinese national standard GB/T 42288-2022 "Safety Regulations for Electrochemical Energy Storage Power Stations" in the field of energy storage was officially released with the approval of the State Administration for Market Regulation, and will be officially implemented on July 1 this year. The regulations mainly put forward clear safety requirements for the equipment and facilities, operation and maintenance, maintenance tests, and emergency disposal of energy storage power stations. The scope of application includes lithium-ion batteries, lead-acid (carbon) batteries, liquid flow batteries, water electrolysis hydrogen production/fuel cell energy storage power stations.
Safety is always a hot topic in energy storage. The document requires that electrochemical energy storage power stations should establish a dual prevention mechanism for safety risk classification management and control and hidden danger investigation and governance; power stations should formulate emergency plans for production safety accidents, including accidents such as battery thermal runaway, fire, electric shock, mechanical injury, and natural disasters.
Besides, the main clauses of the regulations have repeatedly mentioned that combustible gas detection, temperature detection, smoke detection, hydrogen H2 detection and other measures should be used to ensure the safety of energy storage systems.
01 Lithium Battery Energy Storage Safety Monitoring
Electrochemical energy storage, especially lithium battery energy storage technology, has excellent comprehensive performance and a wide range of application scenarios. Under the cost reduction driven by the scale effect, it is expected to usher in a stage of rapid expansion and development. As an important technology to help new energy to grow, energy storage safety issues have become the focus of common concern in the industry. Compared with post-event remediation, prevention measures have become the top priority.
Based on the thermal runaway mechanism of lithium phosphate batteries, thermal runaway will precipitate combustible gases such as H2, CO, and alkanes. Installing combustible gas detectors in the battery has gradually become a requirement of international standards, such as the Chinese standard GB 51048 and the American standard NFPA 855. Combustible gas, carbon monoxide CO, hydrogen H2, VOC and other gas detection equipment have become necessary.

02 Hydrogen Energy Storage Safety Monitoring
In the trend of carbon neutrality and energy storage, hydrogen energy storage will become the best choice for long-term, large-scale energy storage scenarios, and is the key to carbon neutrality in the field of non-electric energy consumption. However, H2 is not easy to contain and prone to leak. As a fuel gas easy to combustion and explosion, it’s very important to detect and monitor the leakage problem. H2 gas detectors, gas control cabinets and other equipment will be popular supporting facilities.
For hydrogen leakage problem, Winsen has developed a variety of H2 sensors and modules which provide safety solutions for hydrogen energy storage.
