A hydrogen fuel cell truck, also known as a hydrogen fuel cell electric vehicle (FCEV), uses hydrogen gas as the fuel to generate electricity in the fuel cell, which in-turn powers an electric drive motor that propels the vehicle. This offers a clean and efficient alternative to gas and diesel-powered trucks while retaining a diesel-like fueling experience, meaning a full fill in 15 to 20 minutes. ​
​In commercial transportation applications, Class 8 included, electric drive motors offer significant power and torque benefits for handling heavy loads and navigating varying terrain. Electric drive motors, designed with high torque capability, provide necessary pulling power, delivering instantaneous torque from the start. This is advantageous in hauling heavy loads. In addition, electric drive systems can recover energy through regenerative braking, where the vehicle's kinetic energy can be captured as electrical energy during deceleration and braking. This energy is captured and stored in a battery, increasing overall efficiency, and extending the vehicle's range. ​
