The production of green hydrogen through electrolysis is seen as a promising solution for the global energy transition. Green hydrogen is favored as it has the potential to decarbonize entire industries. To push the "green transformation," reliable electrolysis processes as well as hydrogen testing solutions are required. HORIBA FuelCon's testing and production solutions help various industries, such as the energy and automotive sector, shipping, aviation, environment and science, to realize the transition to new energies.
Electrolysis describes the process of a chemical cleavage in which a redox reaction is forced by electric current. Electrolyzers are used in a wide variety of technical substance separations - including the production of hydrogen. An electrolyzer splits water into oxygen and hydrogen. If only electricity from renewable energies such as solar, wind or hydroelectric plants is used to produce both components, the product is called green hydrogen.
The technology of electrolysis corresponds to the operating principle of a fuel cell - only in reverse. In a fuel cell, hydrogen and oxygen react to water vapor, where during electron transfer electrical energy is also converted.
Germany is making a major contribution to global hydrogen research and is steadily expanding its activities in the field of electrolysis. The number of electrolyzers and their test stations, which are used to test functionalities and operating strategies, is increasing at the same time. Each of the different electrolyzer technologies requires a customized test and production solution. HORIBA FuelCon is your reliable partner for your hydrogen test solution needs.
There are three main types of water electrolyzers, which differ mainly in the electrolyte used, the operating temperature or the design of the electrolysis cell:
Pure water is fed into the anode of the electrolyzer, where it is split by a catalyst. Oxygen is produced directly on the anode side, whereas the hydrogen ions are passed through a solid polymer membrane and react on the cathode side to form hydrogen.
Water vapor is electrolyzed at high temperatures of around 900 °C. The additional thermal energy reduces the power requirement of the reaction and enables very high efficiencies.
Pure water is fed into the cathode of the electrolyzer, where it is split by a catalyst. Hydrogen is produced directly on the cathode side, whereas the oxygen ions are passed through an alkaline solution and react to form oxygen on the anode side.
