Japan's First Hydrogen Hybrid Train Takes to the Tracks
On February 28th, 2023, the media witnessed the test run of Japan's first hydrogen hybrid train, the Hybari, on the JR Tsurumi Line in Kanagawa Prefecture. This innovative train, powered by electricity generated from hydrogen, represents a significant step towards East Japan Railway Co.'s (JR East) goal of decarbonizing railroads by 2030.
The Hybari boasts a fuel cell that generates electricity through the reaction of hydrogen and oxygen, alongside storage batteries. This technology, developed in collaboration with Toyota Motor Corp. and Hitachi, aims to replace diesel trains currently operating on non-electrified lines.
During the test run between Tsurumi and Ogimachi stations, a monitor inside the two-car train displayed the real-time power source for motors and lighting, switching between the fuel cell and battery depending on acceleration and deceleration.
With a current range of 140 kilometers, the Hybari faces the challenge of extending its reach. However, its development marks a promising advancement in the pursuit of environmentally friendly rail transportation.
Meanwhile, Central Japan Railway Co. (JR Tokai) is exploring an alternative approach to railcar decarbonization. They are developing trains with hydrogen engines that directly power the motors, eliminating the need for diesel engines.
The race towards a greener future for Japan's railroads is on, with both hydrogen hybrid and hydrogen engine technologies vying for the lead. The Hybari's test run signifies a crucial step in this journey, paving the way for a cleaner and more sustainable transportation system.
