Construction of a simple HHO generator, made of stainless steel washers and a water bottle.An hydrogen generator, like this one, uses electricity from your a battery to split water into hydrogen and oxygen gasses.
Methods to produce hydrogen without the use of fossil fuels involve the process of water splitting, or splitting the water molecule H2O into its components oxygen and hydrogen. When the source of energy for water splitting is renewable or low-carbon, the hydrogen produced is sometimes referred to as green hydrogen. This video shows step-by-step how to make one.
Electrolysis consists of using electricity to split water into hydrogen and oxygen. Electrolysis of water is 70–80% efficient (a 20–30% conversion loss) while steam reforming of natural gas has a thermal efficiency between 70–85%. The electrical efficiency of electrolysis is expected to reach 82–86% before 2030, while also maintaining durability as progress in this area continues at a pace.
By placing two electrodes (metal plates) into water we can create an electric field between them by connecting them to the terminals of a battery or power supply. The positive electrode is known as the anode, while the negative one is the cathode. Pure water actually does not conduct electricity so it is not suitable to be used without adding something to the water.Disclaimer: Dont try this at home.
