The hydrogen production efficiency of anion exchange membrane (AEM) high-pressure electrolyzers surpasses that of conventional alkaline electrolysis technology, and its material costs are more favorable than proton exchange membrane (PEM) technology. This technology offers advantages such as reduced usage of precious metals, high-pressure output, and adaptability to fluctuations in renewable energy. The hydrogen production efficiency of this technology can reach 65%, and it can operate at low alkaline concentrations (<1M KOH), providing operational and maintenance advantages. Additionally, the ability to directly generate hydrogen at 30 bar pressure reduces pipeline transportation costs or lowers the energy consumption for high-pressure storage on the back end.
