I am truly unimpressed with this Power to Hydrogen #P2H2 "hybrid AEM electrolysis technology". P2H2 AEM patent US10844497B2 shows electrolyzer data stopping at 100 mA/cm2. Commercial PEM electrolyzers operate up to 3000mA/cm2-30x greater current density #H2 #hydrogen #GreeenHydrogen #electrolysis

Does anybody want to hazard a guess on what is hybrid about this "hybrid AEM electrolysis technology"? Perhaps it is their use of "hybrid power purchase agreements" that makes it "hybrid"? (I'm almost #ROFL with this "hybrid" claim...)
