ENERGY ON THE GO

Modular, High-Voltage Energy Storage Systems

Rail operators need battery systems that scale by route and drive cycle—without forcing a ground-up redesign. Turntide’s modular high-voltage architecture lets OEMs right-size energy and power using repeatable building blocks, then expand as requirements evolve.

Rail Applications

Intercity Tri-Mode Trains (Battery | Electric | Diesel)

Extend battery operation to locations where overhead electrification is unavailable or prohibitively costly to implement (particularly tunnels and bridges), reduce engine run time, and improve station-area air quality through battery-only arrivals and departures. Turntide's modular high-voltage battery systems are already being deployed with Hitachi Rail to enable cleaner, quieter intercity service.

Retrofit Battery-Hybrid Conversions

Upgrade existing fleets faster than full infrastructure buildouts, using scalable battery modules to replace or downsize diesel generation while maintaining range and timetable performance. Turntide’s modular architecture supports rapid deployment and serviceability—designed to minimize downtime during conversion.

Regional & Commuter Operations

High stop frequency and variable loads demand robust thermal management, predictable power delivery, and long lifecycles. Battery capability can reduce noise and emissions in dense population corridors while improving operational flexibility. The Turntide battery system’s design is informed by duty-cycle simulation and rail standards to support real-world reliability.

Geofenced & Sensitive-Zone Operation

Battery-only operation in stations, city centers, and tunnels helps operators meet local requirements without compromising network coverage. Turntide high-voltage battery systems are engineered for safe, controlled transitions between power modes and repeatable deployment across routes.

Leading the Hybrid Era with Proof, Not Predictions

Easily Retrofit

Modular design is ideal for retrofits—it causes minimal disruption, so trains can be updated and returned to service quickly.

Charge on the Move

Battery enables about 90-km to 100-km battery operation and can recharge via overhead wires and from regenerative braking while in motion.

View case study

Environmental

Expected impacts include about 20% to 30% carbon savings and up to a 30% fuel cost reduction plus documented trial claims of 30% to 50% fuel cost reduction in 2024 intercity trial messaging.
