How and why is hydrogen fuel more efficient than regular gasoline?
assistant
Hydrogen fuel is more efficient than regular gasoline due to its higher energy density per unit volume. This means that a given volume of hydrogen fuel stores more energy than an equivalent volume of gasoline. Furthermore, when hydrogen fuel is burned, it produces fewer emissions than gasoline, resulting in a cleaner burn and less pollution. Additionally, hydrogen fuel is easy to obtain and can be used as an alternative energy source to reduce a vehicle’s impact on the environment.
