Specialist fire detection, suppression and security for BESS and grid-scale battery facilities — matched to the risk profile of the technology.
The Landscape
Lithium-ion battery energy storage brings fire risks that conventional systems weren't designed for — thermal runaway, toxic off-gassing and cascading cell failure among them.
The UK's clean energy build-out is accelerating, and so is the regulatory conversation around it. Getting fire protection right at design stage avoids expensive retrofit, insurance headaches and — worst case — losing the asset.
The Risk Profile
BESS fire protection starts with understanding why lithium-ion fires behave differently — and designing accordingly.
Once a cell starts, heat cascades to neighbours. Early, sensitive detection and containment buy the only time that matters.
Flammable and toxic gases appear before flame. Dedicated off-gas detection catches failures before they escalate.
Conventional gaseous suppression often can't control lithium fires. Watermist and hybrid approaches change the equation.
Fires can re-ignite hours after "extinguishment". Monitoring and cooling strategy extends well beyond the incident itself.
Technology Partner
Watermist cools lithium cells and suppresses flame in a way gaseous suppression can't. As Fogtec's UK partner, Photuris delivers container-level and facility-level BESS watermist to UK sites — engineered to the specific thermal profile of the battery technology involved.
Integrated Solution
We integrate aspirating smoke detection, off-gas sensors and Fogtec watermist into a single coordinated BESS fire system — with a clear escalation sequence and interlocks with HVAC and BMS.
Who We Work With
BESS developers, EPC contractors, O&M providers and investors — helping to manage fire risk across the asset lifecycle.
Our Approach
BESS projects reward early engagement — the design decisions made in the first weeks determine what's possible in the last.
01 Inception
We engage at the earliest stage to de-risk projects, influence design decisions and embed fire and security requirements from the ground up.
