Question

Fuel cell cars that use hydrogen as fuel have the potential to be quiet, produce low emissions, and require less maintenance than gasoline cars. What negative effect might hydrogen fuel have on the environment?

Answer 1

Advocates for the use of hydrogen fuel cells posit that unlike other sources of power, these fuel cells do not emit harmful carbon emissions in the air that cause pollution and affect global warming. Although the chemical process involves burning hydrogen, it emits water, heat and other emissions but not carbon.

I hope my answer has come to your help. God bless and have a nice day ahead!

Answer 2

Answer:

The production of hydrogen releases CO₂.

Explanation:

Hydrogen is not a primary fuel, it means that it is not available to be used directly, it must be produced. The production generally uses fossil fuels, and in that case, CO₂ is produced, which is a greenhouse gas (GHG).

So, to obtain that fuel, CO₂ is released, which has a negative effect on the environment because it intensifies the greenhouse effect and global warming.
