Hydrogen-powered vehicles

Definition

Hydrogen-powered vehicles are types of transportation that utilize hydrogen as a primary fuel source, converting it into electricity through fuel cells to power electric motors. These vehicles are considered a promising solution for sustainable transportation, as they produce only water vapor as exhaust, making them environmentally friendly. The shift toward hydrogen-powered vehicles is part of a broader movement to reduce reliance on fossil fuels and minimize greenhouse gas emissions.
