Methane is used as fuel for heating devices, engines, fuel cells, and gas turbines that generate electrical energy, as well as in many industrial chemical processes. It has also been regarded both as a fossil fuel and as a renewable energy source. Although it shows high potential to become an environmentally safe motor fuel, given its cleaner exhaust and abundant occurrence, it is also a potent greenhouse gas (GHG) 25 times more powerful than carbon dioxide in effecting climate change.
