Even though few incidents with domestic battery energy storage systems (BESSs) are known in the public domain, the use of large batteries in the domestic environment represents a safety hazard.
Are domestic battery energy storage systems safe?
In September 2020, the UK government published a review of safety risks related to domestic battery energy storage systems. In the document, it acknowledges that 'few incidents with domestic battery energy storage systems are known in the public domain'. At the same time, the report recognises that relevant safety measures need to be implemented.
Are large battery energy storage systems a safety hazard?
Even though few incidents with domestic battery energy storage systems (BESSs) are known in the public domain, the use of large batteries in the domestic environment represents a safety hazard.
Most Home energy batteries use Lithium Iron Phosphate technology (LiFePO4). Whilst this technology makes for a heavier battery, it is known to be very safe and does not catch fire under any normal circumstances. Under the new standard, batteries shall not be installed in any of the following locations:
Can home energy storage batteries catch fire?
It should be noted that fires from domestic home energy storage batteries are extremely rare. Most Home energy batteries use Lithium Iron Phosphate technology (LiFePO4). Whilst this technology makes for a heavier battery, it is known to be very safe and does not catch fire under any normal circumstances.
Should batteries be used for domestic energy storage?
The application of batteries for domestic energy storage is not only an attractive 'clean' option to grid supplied electrical energy, but is on the verge of offering economic advantages to consumers, through maximising the use of renewable generation or by 3rd parties using the battery to provide grid services.
For years, many people saw energy storage as a novelty or the preserve of people living off-grid. Now technological developments and the growth of domestic renewable energy mean this an area with big potential. Energy storage works well with the idea of the 'smart home'.
