Hydrogen production using renewable energy resources would not create such emissions, but the scale of renewable energy production would need to be expanded to be used in producing hydrogen for a significant part of transportation needs. [137] In a few countries, renewable sources are being used more widely to produce energy and hydrogen.
A vehicle fueled with pure hydrogen emits few pollutants at the tailpipe, producing mainly water and heat, along with trace amounts of NOx, SOx, NO2, SO2, CO, hydrocarbons and particulates; [131] the production of the hydrogen generally creates pollutants, except for the small amount that is made using only renewable energy. [132]
Creating pure hydrogen for vehicles requires using a great deal of energy to "crack" a compound like natural gas (CH4) into pure H2, with CO2 as a byproduct. (Most natural gas today is derived ...
This is a list of fuel cell vehicles (FCV), or fuel cell electric vehicles (FCEV), that use a fuel cell to power an electric drive system. For Hydrogen internal combustion engine vehicles (HICEV) see the List of hydrogen internal combustion engine vehicles .
In the light road vehicle segment, by the end of 2022, 70,200 hydrogen fuel cell electric vehicles had been sold worldwide, [87] compared with 26 million plug-in electric vehicles. [88] With the rapid rise of electric vehicles and associated battery technology and infrastructure, the global scope for hydrogen’s role in cars is shrinking ...

The hydrogen bus was manufactured in Caxias do Sul. The programme, called "Ônibus Brasileiro a Hidrogênio" (Brazilian Hydrogen Autobus), includes three additional buses. [34] In 2010, eight hydrogen buses were introduced into service in London, with a substantially larger range than the fuel cell buses used in the mid-2000s.
