Application of Fuel Cell and Green Hydrogen Technology in Buses for Public Urban Transport Passengers

Abstract

The system of public urban passenger transport is one of the most important functions of any city. The bus subsystem is still the most prevalent in most cities of the world. In addition to the proven advantages in use, the main demands placed on the bus subsystem are environmental suitability and neutrality, through the increasing use of buses with zero and low emission of harmful exhaust gases. Fuel cell-powered buses using green hydrogen are currently a technology with great potential with the goal of completely decarbonizing carbon dioxide (CO2) emissions originating from the bus subsystem. The paper will present the basic characteristics of fuel cell buses, legal frameworks for application in the countries of the European Union, and experiences in the application of this drive concept in some cities.
