Battery electric vehicles, (BEVs) & hydrogen fuel cell electric vehicles, (FCEVs) don't produce any pollution at the tailpipe however, both have the potential to produce pollution when their "fuel" is created.
Are (FCEVs) greener than (BEVs)?
Hydrogen Fuel Cell
How does the Hydrogen Fuel Cell work?
Where does the electricity and hydrogen come from?
Today, electricity is sourced from a range of power sources; renewables, nuclear, and in the majority of cases electricity is still produced by the burning fossil fuels, coal and gas.
In the case of hydrogen, this fuel is mainly produced by the steam reformation of fossil fuels such as natural gas. With the emerging hydrogen economy “green hydrogen” using the electrolysis of water from wind, hydro or solar photovoltaic energy are viable alternatives that offer zero emission hydrogen energy.
(BEVs) and (FCEVs) both have the potential to offer non-polluting forms of transportation, but we do need to quickly move away from producing electricity by burning fossil fuels. Instead, we need to embrace wind, solar and hydro-electric generation.
“Hydrogen has higher energy storage density than lithium ion batteries, both in terms of energy stored per unit weight and energy stored per unit volume”.o edit.
