With the current push toward exploring the use of alternative fuel sources to power automobiles, research continues to be conducted to determine if hydrogen gas should be the alternative fuel of choice. Hydrogen gas can be used to power certain types of internal combustion engines, which are similar to gasoline-powered automobile engines. Hydrogen gas can also be used in fuel cell vehicles that run on electricity.

Reflect and discuss the pros and cons of hydrogen gas as an alternative fuel for automobiles. Would you consider purchasing a hydrogen-powered automobile for yourself or your family? Why, or why not?
