The reduced size of the liquid-cooled storage container has many beneficial ripple effects. For example, reduced size translates into easier, more efficient, and lower-cost installations. “You can deliver your battery unit fully populated on a big truck. That means you don't have to load the battery modules on-site,” Bradshaw says.

Are liquid cooled battery energy storage systems better than air cooled?

Liquid-cooled battery energy storage systems provide better protection against thermal runaway than air-cooled systems. “If you have a thermal runaway of a cell, you've got this massive heat sink for the energy be sucked away into. The liquid is an extra layer of protection,” Bradshaw says.
