Hydrogen fuel cell trucks are vehicles that use hydrogen gas to generate electricity, which powers an electric motor. These trucks convert hydrogen and oxygen from the air into electricity through a chemical reaction, producing only water vapor as a byproduct. This makes them an environmentally friendly alternative to traditional diesel trucks. These trucks are designed for long-haul transportation, offering a longer range and faster refueling times compared to battery electric trucks. As the demand for cleaner transportation grows, hydrogen fuel cell technology is being explored as a viable solution to reduce greenhouse gas emissions in the trucking industry.
