Example Question #2 : Other Energy Sources
Which of the following is NOT a drawback of utilizing hydrogen as a fuel source?
Possible Answers:
Hydrogen has a low energy density by volume.
Existing infrastructure for manufacturing and transporting hydrogen is minimal to nonexistent.
Hydrogen is very challenging and dangerous to transport.
The input of energy to produce hydrogen is often greater than the energy of the resulting hydrogen.
Hydrogen has a low energy density by weight.
Correct answer:
Hydrogen has a low energy density by weight.
Explanation:
Hydrogen is very challenging to transport and it requires a large energy investment to produce it. While hydrogen has a low energy density by volume, it actually has a very high energy density by weight. This has to do with the fact that hydrogen, discussed in this context, is a gas.
