1. East Japan Railway Company Hydrogen-hybrid Train (FV-E991 Series)
Decarbonization efforts are accelerating worldwide to achieve a sustainable society.
As part of these efforts, East Japan Railway Company developed the FV-E991 series (HYBARI: hydrogen-hybrid advanced rail vehicle for innovation), a hydrogen-hybrid train that uses fuel cells, with the goal of diversifying energy sources.
Hitachi greatly contributed to the project. It was contracted to develop the main circuit*1 system of the FV-E991 series; produced the power conversion equipment*2, main circuit battery, and traction motor; and managed the hybrid system including the fuel cell system. The main circuit system of the FV-E991 series covers various functions such as vehicle driving control, charge and discharge control of the main circuit battery, and output control of the fuel cell system. Hitachi collaborated with East Japan Railway Company, who manages the entire project, and Toyota Motor Corporation, the fuel cell manufacturer, to implement and operate the vehicles on the main line.
Since March 2022, it has been conducting verification tests (e.g., vehicle performance evaluations) on the Nambu Line (between Kawasaki and Noborito), the Tsurumi Line, and the Nambu Line Shitte Branch Line, and continues to work with East Japan Railway Company to promote the practical use of hydrogen-hybrid trains.
