What colour name is commonly given to hydrogen produced from renewable electricity by the electrolysis of water?

Answer and explanation

Correct answer: A. Green hydrogen

  1. Step 1: Green hydrogen is usually understood to be produced from renewable electricity via electrolysis of water. Most hydrogen is gray hydrogen made through steam methane reforming, and blue hydrogen is made using steam methane reforming with carbon capture and storage. Answer: Green hydrogen. Why not the others: Grey hydrogen is made through steam methane reforming, not electrolysis with renewable power; blue hydrogen is made using steam methane reforming with carbon capture, not renewable electrolysis; hydrogen peroxide is a different chemical compound and not a colour name for hydrogen fuel.
