The hydrogen used is stored in compressed tanks, either on the roof or the back of the bus. Battery electric buses, on the other hand, operate solely on electricity stored in large batteries, which are charged from an external power source.
With the push for sustainable transportation, battery electric and hydrogen buses are becoming central to discussions on public transit innovation. Cities across the globe, from Europe to Asia, are exploring how these zero-emission vehicles can replace traditional diesel buses and reduce greenhouse gas emissions.
Both battery electric and hydrogen fuel cell buses contribute significantly to reducing carbon dioxide and other harmful emissions in urban areas, making them essential to achieving net zero emissions goals. Their zero emissions operation not only benefits air quality but also reduces noise pollution.
As of 2020, 5,648 hydrogen fuel cell buses are in use around the world, with 93.7% of them in China. A wide variety of companies are currently producing hydrogen fuel cell buses. Bus manufacturers usually work with a provider of hydrogen fuel cells to power the bus, such as Ballard Power Systems or Toyota.
Hydrogen is a fuel that is ideal for powering heavy-duty, large-scale vehicles, including buses, which are essential for urban transport. Bus manufacturers like Solaris use hydrogen to produce electricity, enabling buses to travel even greater distances with absolutely no emissions and low noise and vibration.
Hydrogen fuel cell buses generate electricity through a process that combines hydrogen and oxygen within a fuel cell. During this reaction, hydrogen molecules split into protons and electrons, producing an electric current that powers the bus.
