Electrolyzers are critical for green hydrogen production, splitting water into hydrogen and oxygen via electricity from renewables. As of early 2026, the global market is dominated by alkaline (AWE) and proton exchange membrane (PEM) technologies, with anion exchange membrane (AEM) and solid oxide electrolysis cells (SOEC) emerging. Key efficiencies (based on higher heating value, HHV, system level) vary: AWE (~65-75%, mature and cost-effective for large-scale), PEM (~60-70%,

Have you heard about green hydrogen and wondered how it's actually made? At the heart of it all is something called an electrolyzer. It's like a magical machine that turns water and electricity into clean fuel. In this article, we'll break down electrolyzer technology in simple terms – no engineering degree required! We'll cover what it is, how it works, the different types, their pros and cons, where they're used, and what the future looks like. By the end, you'll understand
