I was aware many data centers throughout the world have chosen to move to new battery technologies for their UPS systems, including lithium-ion batteries and I was afraid there would be a major incident in a data center soon related to the batteries.

In June 2022 I presented on lithium-ion battery fire safety at a data center conference in the U.S. (7x24 Exchange Conference) and warned that this type of incident was coming.

I am afraid this will not be the last one.

There is new code guidance that can make the installation of lithium-ion batteries safer in buildings, but it is not being adopted quickly enough to stem the tide of how these batteries are being installed.

So far in the U.S. there has not been a similar incident in a data center or telecommunications building. The U.S. has had several fires started in lithium-ion batteries in other energy storage facilities.

Moss Landing in Monterey County, California has had multiple incidents with the most recent one in September.

The fire started at the PG&E side of the facility in a Tesla Megapack energy storage unit.

Fire departments are learning how to safely respond to incidents and code-making groups are developing new standards to make new installations safer.

NFPA 855 is the Standard for the Installation of Stationary Energy Storage Systems and applies to most battery installations in commercial buildings, It also applies to existing buildings where the battery technology is being changed(e.g. lithium ion battery retrofits). 

Requirements for installations vary based on the battery type and if the battery is installed in a ‘dedicated building’ or a ‘non-dedicated building’.

Energy storage buildings like at Moss Landing are considered dedicated buildings.

Data centers would be considered non-dedicated buildings because there are more functions in the building than just housing the batteries and have more fire protection requirements.

Other battery chemistries are being researched actively as well as less volatile electrolyte types for lithium-ion batteries.

The challenge will be to deliver performance including high energy densities, long life, and low maintenance close to that of lithium-ion batteries for approximately the same cost.

The batteries should be located on floors where the fire department can easily access them for firefighting.

They need to be separated from other uses in the building by fire walls.

The room needs fire sprinklers with appropriate water flow rates - higher than other areas of the building. It needs smoke detection for early warning of a problem in the building.

And exhaust fans tied to gas detectors to control the buildup of explosive gasses if the batteries have problems.

Other active fire extinguishing systems could be installed in the room to avoid other fires exposing themselves to the batteries causing worse problems.
