Bipolar Membrane Single Element Technology (BM)
thyssenkrupp nucera’s Bipolar Membrane Single Element technology (BM) operates on a single-cell basis, allowing easy maintenance of individual cells without disrupting the other installed cell elements. The latest iteration, BM 2.7v6 plus, features optimized design elements that surpass the 1,980 kWh per metric ton of NaOH barrier at 6 kA/m². Key highlights include an accessible active area of 2.85 m² and extended membrane life during high current density operation beyond 6 kA/m². Additional benefits include energy savings, leak-free operation and independently controlled contact pressure.
Bipolar Ion-Exchange Membrane Process Electrolyzer (BiTAC)
thyssenkrupp nucera’s renowned filter press Bipolar Ion Exchange Membrane Process Electrolyzer, BiTAC technology operates on a filter press basis, ensuring compatibility across all generations for seamless upgrades. The latest iteration, e-BiTAC v7, advancements have achieved a new record low energy consumption of 1979 kWh/t at 6 kA/m². BiTAC requires minimal maintenance space, and the entire electrolyzer can be re-membraned quickly and efficiently.
NaCl-Oxygen-Depolarized Cathode Electrolysis Technology (NaCl-ODC)
NaCl-Oxygen-Depolarized Cathode Electrolysis Technology, NaCl-ODC is based on oxygen-depolarized cathodes (ODCs) integrated into the single-element electrolysis technology (BM2.7 design). The oxygen introduced into the cathode compartment suppresses the formation of hydrogen. This in turn enables NaCl-ODC technology to cut power consumption by up to 25% compared with conventional membrane based technology. This well-proven, reliable technology minimizes power consumption and offers ecological benefits by reducing CO₂ emissions. BM and NaCl-ODC technologies combinable in a single plant thanks to full compatibility of electrolysis cells and brine cycle.
