United Kingdom- A groundbreaking collaboration between Hitachi Rail and key partners is set to transform commuter and suburban trains with cutting-edge battery technology. The partnership, which includes Sunderland-based Turntide Technologies, DB ESG, and the Birmingham Centre for Railway Research and Education (BCRRE), aims to develop smaller, lighter batteries that will boost performance, improve accessibility, and reduce the UK rail sector’s environmental impact.
At the core of this innovation is a next-generation battery pack, 40% smaller with 22% more energy density, thanks to Lithium Iron Phosphate (LFP) chemistry. This efficiency not only enhances performance but also makes trains more inclusive, allowing for lower floors that provide level access at platforms—especially beneficial for passengers with mobility challenges.
Turntide Technologies brings its automotive expertise to help develop the new batteries, while DB ESG focuses on designing the battery enclosures, ensuring features like fire protection, cooling, and electrical integration are in place. These advances are expected to simplify maintenance and retrofit processes for existing train fleets.
Building on battery trials already running on the Transpennine route, this project aims to apply battery solutions to both regional and intercity trains, aligning with Hitachi Rail’s global ambitions for battery-powered rail transport.
One of the major advantages of this development is the potential to decarbonize the UK’s rail network, particularly in non-electrified areas currently dependent on diesel engines. Professor Pietro Tricoli of BCRRE is leading efforts to optimize battery performance through simulations on UK routes, helping identify where battery trains can best replace diesel. This work will also provide future engineers with crucial skills in railway innovation.
The £1.4 million initiative, co-funded by the public and private sectors, with Innovate UK offering match funding, is fast-tracking battery innovation for the rail industry. Koji Agatsuma, Chief Technology Officer for Vehicles at Hitachi Rail, highlighted the project’s significance, noting how it draws on expertise from the UK, Italy, and Japan to advance battery technology, with the goal of applying these solutions globally.
This pioneering effort represents a major leap toward cleaner, more efficient rail transport. By potentially eliminating the need for costly electrification or diesel engines, it points to a future of greener, more accessible rail travel in the UK and beyond.
