Question

technician a says that hydrogen exists by itself in nature. technician b says that hydrogen has better specific energy than fossil fuels. which technician is correct?

Answer 1

Technician b says that hydrogen has better specific energy than fossil fuels. so technician b is correct.

Does hydrogen have the highest specific energy?

• Although hydrogen has the highest energy density per mass of any fuel, it has the lowest energy density per unit volume due to its low ambient temperature density, necessitating the development of new storage technologies with the potential for higher energy density.
• Hydrogen is utilized as a rocket fuel and in fuel cells to generate power on some spacecraft because it is beneficial as an energy source or fuel due to its high energy content per unit of weight.
• Since hydrogen has a significantly higher energy content than fossil fuels, less of it is required to carry out any given task.
