Hydrogen Fuel-cell Trucks (Hydrogen Trucks)
Hydrogen Fuel-cell Trucks (Hydrogen Trucks)


A hydrogen fuel cell truck is a commercial, municipal, military or personal heavy duty work vehicle of any size, weight or purpose that uses an all-electric propulsion system that uses a hydrogen fuel cell as its primary energy source. Because hydrogen burns cleanly with no carbon emissions, the main benefits of using hydrogen fuel cell technology are better for truck drivers and owners than diesel or compressed natural gas (CNG) trucks or buses while keeping the air cleaner and reducing potential risks to lung health. .

All fuel cell electric vehicles (FCEVs) run on electricity produced by hydrogen-powered fuel cells. A set of proton exchange membrane electrodes that produce electricity by mixing hydrogen and oxygen. Some of that electricity is used immediately and some is stored in batteries. The electricity generated by recovering brake energy is also stored in the battery. The size and/or number of electric motors required for a truck or bus will depend on the type of work being performed: construction, transportation, cargo handling, or garbage collection. Because the amount of energy stored in the system is determined by its size, a hydrogen fuel cell truck or bus in a non-battery hydrogen tank could have a much smaller battery than a fully electric truck or bus. Hydrogen can also be recharged very quickly to maximize productivity.

Hydrogen fuel cell systems are a relatively new technology and their development and upfront costs tend to be higher than traditional fossil fuel internal combustion engines (ICEs) and many battery electric trucks (BETs). However, this is no longer the case, and the day-to-day operating costs of hydrogen fuel cell systems are lower than ICE and all-battery powered and propulsion systems, especially on heavy duty trucks and municipal buses. It is also important to note that the cost of hydrogen fuel for operators is already low, especially given that the cost of hydrogen fuel is much more efficient when compared to diesel or natural gas systems. This will improve as more hydrogen refueling stations become available in key markets. So, while exact price estimates for hydrogen fuel cells and electric propulsion systems will vary, they are now comparable to traditional systems, and costs continue to fall.
