Aenert news. Invention analysisProton exchange membrane (PEM) electrolysis is a promising method for producing hydrogen. In PEM electrolysis of water, water is separated into oxygen, hydrogen protons, and electrons at the anode, and recombination of protons and electrons occurs at the cathode to form water. Relatively thin polymer electrolyte membranes allow high pressures while providing...
Aenert news. Invention analysisWater electrolysis using a Proton exchange membrane (PEM) is the most promising method for producing high-purity hydrogen and oxygen without carbon oxide emissions. The fundamental difference between this technology and other electrolysis methods is the use of a solid polymer electrolyte (SPE) as a separating membrane, which provides electrical insulation of the...
Aenert news. Invention analysisCurrently, technology of hydrogen production through electrolysisis not competitive with the traditional steam reforming method in terms of either product price or performance. However, the use of steam reforming results in huge emissions of carbon dioxide and requires its subsequent disposal, which is not an easy task. In addition, this option uses fossil fuel –...

Aenert news. Invention analysisHydrogen production through electrolysis is the main hope of renewable energy in creating a full cycle of electricity generation through wind turbines and photovoltaic stations and its intermediate storage. This is necessary to compensate for forced downtime of these generating capacities due to natural cycles. At the same time, additional generation of electricity...
Aenert news. Invention analysisElectrolysis is one of the main technologies for producing green hydrogen. However, to date, hopes for achieving acceptable competitiveness of this technology compared, for example, with steam reforming, have not been justified. The cost of hydrogen produced by electrolysis remains too high for mass production. In addition, another important problem for electrolysis...
