Green hydrogen is a clean energy carrier produced by splitting water into hydrogen and oxygen using electricity from renewable sources such as wind or solar power.
This process, called electrolysis, involves passing an electric current through water in an electrolyser, where hydrogen is released at the cathode and oxygen at the anode. Because the electricity comes from renewables, the entire process generates little to no greenhouse gas emissions.
Once produced, green hydrogen can be stored, transported, and used in a variety of applications. It serves as a fuel for transportation (especially in fuel cell vehicles), a feedstock in industrial processes such as steel and ammonia production, and a means of storing excess renewable energy for later use. As a versatile and low-carbon solution, green hydrogen is considered a key component in the transition toward a more sustainable energy system.
