A technology company built on breakthrough science — making onsite hydrogen peroxide generation a practical reality for industries worldwide.
HPNow was founded on breakthrough research conducted at the Technical University of Denmark (DTU). The core insight was simple but profound: hydrogen peroxide — one of the most useful and versatile oxidants in water treatment — could be generated electrochemically, on-site, from nothing more than water, electricity and air.
What began as academic research has since been translated into a commercially deployed technology with installations in Europe, North America and beyond. HPNow holds patents on the core electrochemical process and the HPGen® product platform.
The incumbent approach to water treatment relies on synthetic chemicals manufactured in centralised factories, transported in concentrated and hazardous form, and dosed on-site. HPNow eliminates every step of that chain.
HPNow's sole focus is the development, manufacture and deployment of systems that generate hydrogen peroxide electrochemically, at the point of use.
Record-high electrochemical efficiencies achieved through HPNow's proprietary oxygen reduction reaction (ORR) cell design — the result of years of material science research and process engineering.
Unlike industrial-grade peroxide (typically 35–70% concentration), HPGen® produces hydrogen peroxide at safe, low concentrations. There is no classification as a hazardous substance — no special handling, no PPE requirements for operators.
Peroxide UltraPure™ decomposes to water and oxygen after treatment — leaving zero chemical residuals in the treated water or discharge. A genuinely closed-loop oxidation process.
HPNow's technology has been deployed in real commercial installations in Europe, North America and beyond — in greenhouses, cooling towers, pharmaceutical facilities, and municipal systems.
Our case studies document measured outcomes: reduced maintenance, eliminated pathogens, regulatory compliance, cost savings. This is not laboratory promise — it is operational proof.
