What is the primary environmental benefit of using hydrogen as a fuel?

Step 1: Understand what hydrogen fuel is. Hydrogen is a clean energy source that can be used for power.
Step 2: Learn how hydrogen is used as fuel. When hydrogen is burned or used in fuel cells, it reacts with oxygen.
Step 3: Identify the byproducts of burning hydrogen. The main byproduct of this reaction is water vapor.
Step 4: Compare hydrogen fuel to traditional fuels. Traditional fuels like gasoline produce carbon dioxide and other pollutants when burned.
Step 5: Conclude the environmental benefit. Since hydrogen only produces water vapor and no carbon emissions, it is better for the environment.
