Science: why are hydrogen fuel cells and biofuels better for the environment that fossil fuels?
I have to write a 500 word essay for my science homework about why hydrogen fuel cells and biofuels could be better for the environment than fossil fuels and it due tomorrow!
Please help me, I have no idea!
Thanks, georgia x
When you burn fossil fuels, you release carbon dioxide into the atmosphere that has been locked away for millions of years. Biofuels are preferable because they capture carbon dioxide during their production, so do not release extra carbon dioxide. They have their disadvantages though, as they use land that should otherwise be used for food.
Hydrogen fuel cells only release water, and not carbon dioxide. While water is also a greenhouse gas, it is less damaging than carbon dioxide. Unlike fossil fuels, a hydrogen fuel cell does not release the other by-products such as nitrogen dioxide which are also very damaging to the environment.
