How immersion cooling works
The whole battery module — cells, busbars, interconnects — sits directly in a dielectric (electrically insulating) fluid. The fluid absorbs heat, physically blocks oxygen at the cell surface, and acts as a barrier against thermal-runaway propagation.
Single-phase
Cells submerged in a liquid that never boils — synthetic esters or PAO-based dielectric fluids (e.g., Shell Certified Battery Dielectric Fluid). Heat is carried away by circulation through a heat exchanger.
- Simpler, cheaper, biodegradable fluids available
- Used in EticaAG Fortis data-center racks and most early commercial BESS
Two-phase
Cells in a low-boiling fluorocarbon that evaporates at the cell surface and condenses in an external condenser — extremely flat temperature distribution.
- Best thermal performance, higher fluid cost
- Proven in HPC/server racks; emerging for high-C-rate BESS
Why it beats air & cold-plate cooling
- Heat removal 10–20× more effective than air; uniform <3°C cell delta
- No hot spots → slower aging, longer cycle life, no derating at high C-rates
- Thermal runaway containment: fluid absorbs the failing cell's energy and excludes oxygen — adjacent cells stayed below ~50°C in 2025 experiments while a failing cell reached ~500°C
- No thermal-runaway propagation in UL 9540A testing (EticaAG Fortis) — the benchmark for BESS fire safety and bankability
1 · Commercial applications
Data centers (AI load buffering, UPS augmentation, peak shaving) and commercial facilities (demand-charge management, solar self-consumption, backup).
Typical immersion-cooled deployments: in-rack batteries for AI data centers (millisecond GPU load swings, e.g. EticaAG Fortis 400: ~224 kWh, 1.74 MW continuous per rack); UPS companion systems (Fortis Sidecar: 233 kWh, 600 kW peak, 30-min runtime); urban/substation-adjacent BESS where fire risk cannot be accepted; commercial peak shaving.
2 · Industrial applications
Manufacturing plants, mining and remote industrial sites: peak shaving, demand-charge reduction, renewable integration, and backup for precision processes (semiconductor, pharma, automotive).
Typical immersion-cooled deployments: high-C-rate load leveling in enclosed plant spaces (no derating, no fire exposure to production lines); substations and basements near production; remote mines and oil/gas platforms where there is no firefighting infrastructure and safety certification is the gating factor; microgrid firming for industrial parks.
3 · Other applications
Microgrids, telecom base stations, EV charging infrastructure, defense/mobile power, and community/residential resilience.
Typical immersion-cooled deployments: island-mode microgrids (campuses, islands, remote communities) where a battery fire would destroy the only power source; 5G/6G base stations in weather-exposed cabinets; fast-charging stations with high-C-rate buffers; military and emergency-response mobile power; residential/community backup in fire-prone areas.
