The Seaside Business Promotion Department, Seaside International Strategy Division, Kawasaki City has been working on this project since FY2017. As part of a comprehensive partnership agreement with JR East concluded in January 2015, Kawasaki and JR East have been promoting “Ecoste (Eco-station)” at JR Musashi-Mizonokuchi Station. The introduction of the hydrogen-based autonomous energy supply system (H2One) has made JR East the first railway company to use hydrogen from renewable energy (CO2-free hydrogen).
