28 март 2022 г. - (JAPAN) JR East trials H2 Locomotive from Tokyo to Kawasaki

Описание:

Rail operator JR East has commenced trials of a hydrogen-powered train in Japan, the first such locomotive in the country. The trial will test the safety and performance characteristics of the new train and will involve a series of studies to be carried out on the Nanbu Line, running between Tokyo and Kawasaki.

JR East is aiming to diversify its energy sources. Promoting the use of hydrogen is part of this effort. We have been proceeding with development of a fuel cell vehicle that uses hydrogen as an energy source,” a spokesperson for JR East commented. The 45-kilometer Nanbu Line connects Tokyo with Kanagawa Prefecture and runs from Tachikawa Station to Kawasaki Station.

The complex fuel cell system that powers the new locomotive has been jointly developed by JR East and technology partners Hitachi and Toyota. Building on Toyota’s previous experience creating fuel cell electric road vehicles, the partners have sought to fine tune its proton exchange membrane (PEM) fuel cell technology for use in rail operations.

A part of the proposed FV-E991 series, the new locomotive will be equipped with a hybrid system that uses a hydrogen fuel cell and a storage battery as its power sources. Instead of combusting fuel in air, the fuel cell system instead reacts hydrogen and oxygen within an electrolyte solution to generate electricity and produce water.

“The main circuit storage battery is charged by electric power from the fuel cell device and by capturing and converting energy to electric power using regenerative braking,” a spokesperson for Toyota explains. “The hybrid drive system supplies the electric power to the traction motors from both the fuel cell device and the main circuit storage battery, controlling the movement of the wheels.”
