Green Hydrogen – Is it a Buzz or a Breakthrough?

Hydrogen is the lightest and simplest element in the periodic table (Atomic number 1). It is also the most abundant element in the universe. The main problem with Hydrogen is that it seldom exists alone in pure form. The element is highly reactive and can form bonds with many elements forming compounds like water (H2O) or methane (CH4). 
Now, here’s where the intrigue begins – hydrogen is not a plug-and-play fuel, it is an energy carrier which means it needs to be extracted first unlike petroleum which can be used directly as a fuel. To use Hydrogen as a fuel, it needs to be obtained in pure form, this is done by splitting molecules of water or methane.
