NREL and Giner ELX Test Operation of High-Current-Density Megawatt-Scale Electrolyzer

NREL is validating the stack efficiency, membrane lifetime, catalyst performance, and cell component durability of Giner ELX's new megawatt (MW)-scale Polymer Electrolyte Membrane-based electrolyzer stack design.

Megawatt-scale PEM-based electrolyzer stack

Successful operation of Giner ELX's new electrolyzer stack design will signal a significant scale-up in electrolyzer technology, enabling multimegawatt energy storage solutions. Where previous PEM-based electrolyzer designs were limited to 150-kilowatt energy generation applications, Giner ELX's design will permit platforms at a scale of 15 MW.
