Nel Hydrogen leads the industry in compact PEM water electrolysis technology that transforms how businesses access hydrogen. Our C, H, and S Series eliminate the costs, logistics, and safety concerns of bulk delivery and cylinder management—producing ultra-high purity hydrogen on-demand, exactly when and where you need it. With outputs from 0.27 to 30 Nm³/h, our systems scale to your application while delivering consistent purity and pressure that bulk suppliers can't guarantee. Designed for rapid deployment with a minimal footprint, most installations are complete in hours, not months. Lower your hydrogen costs by up to 50%, eliminate supply disruptions, reduce your facility's safety profile, and gain the operational flexibility to grow without infrastructure constraints.
