NesoBus – Polish hydrogen bus
NesoBus represents a pioneering achievement in Poland—a zero-emission hydrogen city bus developed entirely by Polish designers and engineers. The project involved collaboration with partners from Europe and around the globe during its design and development stages.
“Does not emit exhaust fumes and cleans”
NesoBus addresses the significant air pollution caused by constant operation of public transport, which adversely affects residents’ health. As a city bus powered by green hydrogen, it stands out as one of the most environmentally friendly options on Polish streets today. This 12-meter-long vehicle accommodates up to 93 passengers, including 37 seated, and boasts an impressive range of approximately 450 km.
According to its manufacturer’s website, NesoBus operates without emitting harmful exhaust gases, producing only water vapor. In fact, it contributes to air purification—an integral feature reflected in its name. “Neso” signifies its role: “Does not emit exhaust gases and purifies” the air, highlighting its commitment to environmental sustainability.
NesoBus is an ideal solution for city dwellers – it eliminates the emission of toxic substances – apart from CO2, it mainly includes nitrogen oxides and dust, in particular fine PM 2.5 dust.

Hydrogen bus – how it works
NesoBus operates as an electric vehicle, utilizing an electric motor powered by a fuel cell that generates electricity through an ongoing chemical reaction between hydrogen and oxygen. This innovative design ensures that the bus does not rely on internal combustion for propulsion. Instead, hydrogen stored in tanks on board reacts with oxygen from the air within the fuel cell. This process produces electricity directly, which in turn powers the electric motor to drive the bus.
One of the significant environmental benefits of NesoBus is its emission-free operation. Unlike traditional combustion engines, which emit pollutants through exhaust gases, NesoBus only releases water vapor from its exhaust pipe. This makes it a zero-emission vehicle, contributing positively to urban air quality and sustainability goals. The integration of hydrogen fuel cell technology into its design marks NesoBus as a pioneering solution in the realm of clean and efficient public transportation.
NesoBus generates electricity on an ongoing basis by taking oxygen from the air and combining it with hydrogen from tanks using a fuel cell. There is no combustion process. The intake air must be fully purified by special filters so that the fuel cell receives pure oxygen. Oxygen then combines with hydrogen to create energy that powers the electric motor. A Nesobus powered by green hydrogen does not emit exhaust gases and purifies the air.
Planned series production
The NesoBus hydrogen bus, developed by the Polsat Plus Group and ZE PAK, underwent testing on the streets of Gdynia and Wrocław between June and July this year. These tests represent the initial phase of introducing zero-emission hydrogen vehicles to Polish cities, paving the way for their potential permanent inclusion in urban fleets. This move mirrors similar deployments already seen in various European cities, indicating a growing trend towards adopting sustainable public transportation solutions.
NesoBus, the manufacturer, has also announced plans to commence mass production starting in 2023. This production will take place at a newly constructed factory located in Świdnik, underscoring the commitment to scaling up production of these environmentally friendly buses. This development marks a significant step forward in promoting cleaner air quality and reducing emissions in urban environments, aligning with global efforts towards sustainable mobility solutions.
