Hydrogen Gas
The Pros and Cons
The Pros
Hydrogen is rich in origin like natural gas and water
Hydrogen is very gentle to the environment, unlike fossil fuels and it’s actually free of pollen
Hydrogen fuel cells in a car doesn’t produces zero discharge; the only thing coming out of the exhaust of the car is heat and water vapor
Making hydrogen fuel cells doesn’t release pollution, made with renewable sources like water and solar energy that are used in the production of fuel cells
Hydrogen fuel is almost 3 times productive as gasoline
Hydrogen could be made domestically from several sources, making our dependence on petroleum imports much smaller
Hydrogen makes no air pollutants or greenhouse gases when it’s used in fuel cells - it produces only nitrogen oxides when burned in the internal combustion engines of the passenger cars
The Cons
Hydrogen isn’t always as clean to make
It’s very expensive to extract hydrogen from water
The non-renewable sources of hydrogen, being natural gas and oil, are inexpensive, but using them drains our fossil fuel supply
The Carbon Dioxide that is released in the production process of hydrogen from the fossil fuels neutralizes any good thing to the environment
Hydrogen that escapes during the making process could break down the ozone layer even more than it already is and inflame global warming
Scientists are still trying to find ways to store hydrogen
Because of it’s low energy density, hydrogen needs to be stored and moved under high pressure in the process making it bulky and impractical
Just like gasoline, hydrogen is very flammable, but unlike gasoline, it doesn’t have an odor
Since it doesn’t have an odor, sensors would be the only way to find out if there was a leak before the hydrogen could combust into flames
There is also an issue on the need to provide enough hydrogen fuel stations for cars all over the country.
