How is Green Hydrogen Produced? 


Hydrogen is the element that is most prevalent in the Earth, however, it is not pure and requires energy to be separated.  

The most common technique is steam methane reforming. Heat and chemical reactions release hydrogen from organic materials such as fossil fuels (mostly methane). However, this is incredibly polluting.   

Green Hydrogen Production

The cleaner technique is to extract hydrogen from water, which is two parts hydrogen and one part oxygen (hence H2O). A strong electrical current passed through a tank of water splits the molecule into its two constituent elements. This is called electrolysis. Electrolysis involves using an electrical current to break down the water molecule into oxygen and hydrogen by electrodes. Green hydrogen is achieved through this electrolysis process powered by renewable energies, such as wind or solar. Thus, no greenhouse gases are released during the creation of hydrogen in this way.
