UK Battery Train Revolution: Turntide, Hitachi Rail & LFP Power

Turntide Technologies to Power UK Battery Train Revolution with Advanced LFP Batteries

In a significant leap forward for sustainable rail transport, Turntide Technologies will supply its next-generation lithium iron phosphate (LFP) battery systems to power nine new battery intercity (tri-mode) trains for Arriva’s Grand Central and Angel Trains in the UK. This landmark deal, announced on July 2, 2025, will see the delivery of advanced, more compact, and powerful battery technology developed by Turntide in collaboration with Hitachi Rail. The project, worth £10 million ($13.7 million), represents a major step towards electrifying the UK rail network and aligns with the 200th anniversary of rail, underscoring a commitment to innovation. This article will delve into the specifics of the LFP battery technology, the project’s impact, and the future outlook for battery-powered rail in the UK and beyond.

Advanced LFP Battery Technology: A New Era for Rail Electrification

The core of this project lies in Turntide Technologies’ Gen 2 LFP battery systems. Unlike traditional lithium-ion batteries, LFP batteries offer several advantages, including increased safety, extended lifespan, and greater thermal stability. These next-generation batteries are also designed to be more compact and powerful, critical for achieving the performance requirements of intercity trains. The LFP batteries, coupled with an advanced battery management system, meet the stringent safety and cybersecurity standards of IEC 61508 and IEC 62243. This is crucial for railway operators, ensuring reliable and secure operation. These batteries have been selected because they fit within the existing train infrastructure and can provide reliable performance for an extensive period.

Partnership and Regional Economic Impact

The collaborative effort between Turntide Technologies and Hitachi Rail, both based in the North East of England, is central to the project’s success. This strategic partnership not only supports technological advancement but also fosters regional economic growth. The North East region, celebrating the bicentennial of the railways, is poised to become a significant hub for battery technology development. This project exemplifies the region’s capacity for innovation in sustainable transport. The exclusive agreement signed in 2020 between Turntide and Hitachi Rail has already delivered the UK’s first intercity battery train trial, completed in 2024, showcasing the successful evolution of their collaboration.

The Significance of Tri-Mode Trains

The nine new trains involved are battery intercity (tri-mode) trains. These trains have been engineered with the capability to switch between different power sources. They can run on battery power, which is especially useful on routes that are not fully electrified. The tri-mode design offers operational flexibility, reduces reliance on diesel power, and contributes to decreased emissions. The tri-mode trains represent a key strategy in the transition towards a greener and more sustainable rail transport network. The design allows for the utilisation of vehicle-to-grid technology in the future, optimising energy usage.

Hitachi Rail’s Strategic Investment and Future Developments

Hitachi Rail has demonstrated its commitment to further innovations in the rail sector with an additional £10 million investment in Turntide Technologies, supporting the growth of battery innovation. The company is at the forefront of delivering greener, quieter rail journeys and creating advanced manufacturing opportunities while unlocking energy optimisation using vehicle-to-grid technology. In addition to the battery train project, Hitachi Rail is also involved in designing and implementing advanced signalling systems at Kapıkule Station in Türkiye, further showcasing its global presence and commitment to railway advancement.

Conclusion

The collaboration between Turntide Technologies and Hitachi Rail marks a pivotal moment for sustainable rail transport in the UK. By deploying advanced LFP battery technology in the new tri-mode trains, the project sets a new standard for efficiency, environmental responsibility, and regional economic impact. The successful integration of these technologies not only underscores the advancements in battery technology but also signifies a broader shift towards sustainable transport solutions across the globe. The project’s focus on innovation and collaborative partnerships provides a pathway toward a future where railway transport is greener, more efficient, and better integrated with sustainable energy systems. The potential for vehicle-to-grid technology further enhances the long-term viability of the project, promising not only a cleaner environment but also economic benefits through optimised energy management. The 200th anniversary of the railways is therefore celebrated by a focus on innovation and the use of cutting-edge technology to drive the industry’s future.
