Green hydrogen is produced using clean electricity and water

Green hydrogen is produced via electrolysis, a process that uses electricity to split water (H2O) into hydrogen (H2) and oxygen (O2). 1 This method involves passing an electric current through water in an electrolyzer, which separates the hydrogen and oxygen molecules. The electricity required for this process is generated from clean energy sources and thus is free from carbon emissions. 2
