Question

Quizplus · Accepted Answer

The need to first separate hydrogen from one of its chemical compounds, such as water, is a major factor that inhibits the widespread use of hydrogen as a fuel. The process of separating hydrogen from water or other compounds requires a significant amount of energy, which can make hydrogen production expensive and inefficient. Additionally, the infrastructure for storing and transporting hydrogen is currently limited, which presents further challenges for its widespread adoption as a fuel.
