HYDROGEN FUEL CELL ELECTRIC VEHICLES (FCEVs)
What is hydrogen and where does it occur?
Hydrogen is the first and most important element in the universe. Under normal or standard conditions, hydrogen is a colorless and odorless gas.
Can hydrogen be used as a fuel for vehicles?
Hydrogen can be stored and transported in liquid or gaseous form. It has high energy density, making it an ideal fuel source in transport or industry feedstock.
Hydrogen fuel cell electric vehicles (FCEVs), are powered by electricity and produce only water vapor as a tailpipe emission. In these vehicles, energy is stored in the form compressed hydrogen fuel, rather than in a battery.
The hydrogen fuel-cells convert compressed hydrogen from their fuel tanks into electricity that powers the electric motor in the vehicle, providing a similar range to vehicles powered by internal combustion engines using diesel.
Hydrogen-powered trucks can cover long distances, and only take a few minutes to refuel.
How hydrogen is produced?
Hydrogen is abundant but is rarely found in its pure form. It has to be produced through chemical reactions. Most of hydrogen today is produced through fossil-fuel reforming, a process that produces a reaction between natural gas and steam. Hydrogen can also be produced from renewable sources, for example through electrolysis using electricity generated by renewable sources.
How is hydrogen made and where does it come from?
GREEN HYDROGEN
Hydrogen produced via electrolysis, by splitting water into oxygen and hydrogen, using electricity from renewable sources is sometimes called green or decarbonized hydrogen.
BLUE HYDROGEN
Hydrogen produced from natural gas and later decarbonized by using carbon capture and storage to store any carbon emissions safely back underground.
GREY HYDROGEN
Hydrogen produced using energy from hydrocarbons, particularly natural gas.
