How electrochemical onsite generation works — and the HPGen® product range that delivers it.
HPNow's core technology is the direct electrochemical synthesis of hydrogen peroxide from only three inputs: water, electricity and air. The process takes place inside a compact electrolytic cell, where oxygen from air undergoes reduction at the cathode to form hydrogen peroxide in an aqueous solution.
The breakthrough lies in the electrode design and membrane architecture — a solid polymer electrolyte membrane replaces liquid electrolyte entirely, eliminating a major source of complexity, maintenance and contamination risk.
The HPGen® system integrates the full process chain — from commodity inputs to dosed, treated water — in a single compact unit.
The contrast with conventional industrial hydrogen peroxide procurement is stark — in cost, safety, sustainability and regulatory exposure.
A fully self-contained, compact unit generating Peroxide UltraPure™ on demand — from only electricity, water and air.
Designed for decentralised applications where space and simplicity are priorities. Minimal installation footprint, plug-and-play commissioning, and autonomous operation with remote cloud monitoring.

HPNow's proprietary cathode catalyst achieves record-high selectivity for the 2-electron oxygen reduction pathway — the specific reaction that produces hydrogen peroxide rather than water. This drives both efficiency (lower energy per kg H₂O₂) and product purity. The catalyst design is protected by HPNow's core patents and has been validated across thousands of operating hours in commercial deployments.
By using a membrane-form electrolyte instead of a liquid electrolyte solution, HPNow eliminates an entire category of system complexity. There is no electrolyte management, no contamination risk from electrolyte degradation, and no liquid-phase chemistry to control. The membrane architecture also enables a compact, sealed cell design with no moving parts in the electrochemical stack itself.
HPGen® produces hydrogen peroxide electrochemically at low concentration and on demand, minimizing the need for concentrated chemical inventory on site. This reduces handling and storage hazards while supporting a safer and more controlled treatment process.
