The higher the energy density of the battery energy storage system needs to consider noise and fire safety issues

With the widespread application of lithium-ion battery energy storage systems, it is becoming increasingly difficult to find suitable construction land. This makes energy density an increasingly important consideration for developers when deploying battery storage systems, and battery storage system suppliers can now provide up to 5MWh of energy in 20 foot containers.
However, energy storage systems with higher energy density also need to consider other issues. Engineering, Procurement, and Construction (EPC) firm Burns&McDonnell recently wrote an article on this topic.
Burns&McDonnell safety expert Ben Echeverria and engineering manager Josh Tucker pointed out in the article that increasing energy density when designing and deploying battery energy storage systems may bring more complex issues during on-site installation and handling of energy storage projects.
Another source from the energy storage project developer said that the increase in energy density of battery energy storage systems also means that their operating noise is higher, which is particularly prominent in densely populated countries such as Europe and may require additional fire safety measures.
He said, "The higher the energy density, the greater the noise of battery energy storage systems, and they have more energy in smaller areas, so effective cooling is necessary, so it may not be deployable in some areas or spaces. In other markets in the UK and Europe, noise solutions for battery energy storage systems are really important, but in the larger space of the United States, they may not be as important.". In Europe, noise is an important consideration for deploying battery energy storage systems
These noises typically come from the cooling system of battery energy storage systems, as well as inverters and transformers. Although a solar+energy storage project planning document released by the UK states that the noise level of the Gridsolv Quantum battery energy storage system from the energy storage system integrator Wartsila can be as low as 70-80 decibels, equivalent to the level of a washing machine or vacuum cleaner.
The company recently released the latest version of the Gridsolv battery energy storage system, claiming to improve fire safety and energy density. It should be said that the noise of battery energy storage systems is still much lower than that of thermal power plants, and they are increasingly replacing diesel generators (when off grid).
As sources have pointed out, in addition to noise, battery energy storage systems with significantly higher energy density than industry standards may increase fire safety considerations.
He said, "Interestingly, some correlation can be found between fire protection systems and battery energy storage systems with higher energy density, even though everyone follows the same strict testing standards. This makes sense as batteries emit heat, and eliminating heat is important. If more batteries are installed in a smaller space, it will be difficult to achieve this.". I believe that energy storage integrators who design and deploy higher energy density systems have also invested a lot of work in cooling systems
