Technology & Product

How electrochemical onsite generation works — and the HPGen® product range that delivers it.

Direct Electrochemical Synthesis of Hâ‚‚Oâ‚‚

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.

  • No liquid electrolyte — solid membrane electrolyte only
  • No gaseous hydrogen produced as a by-product
  • No vaporized water inputs required
  • Record electrochemical efficiency via proprietary ORR catalyst
  • Produces low-concentration, high-purity Peroxide UltraPureâ„¢

From Three Inputs to Treatment

The HPGen® system integrates the full process chain — from commodity inputs to dosed, treated water — in a single compact unit.

Onsite vs. Conventional Chemical Treatment

The contrast with conventional industrial hydrogen peroxide procurement is stark — in cost, safety, sustainability and regulatory exposure.

âš  Conventional Chemical Procurement

  • High-concentration Hâ‚‚Oâ‚‚ (35–70%) classified as hazardous
  • Requires specialist transport and storage infrastructure
  • Significant supply chain emissions and logistics cost
  • Strict PPE and handling protocols for operators
  • Dependent on third-party supply — price and availability risk
  • Chemical residuals in discharge raise regulatory concerns
  • Multiple synthetic chemical additives often required

✓ HPNow Onsite Generation

  • Low-concentration Peroxide UltraPureâ„¢ — not classified hazardous
  • Generated on demand at point of use — no storage tanks
  • Zero transport emissions — only electricity, water and air needed
  • No specialist handling — safe for standard operators
  • Complete supply independence — no procurement risk
  • Breaks down to water and oxygen — zero residual discharge
  • Single autonomous system replaces multiple chemical programmes

Three Core Technology Advantages

1

Breakthrough Oxygen Reduction Reaction (ORR)

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.

2

Solid Polymer Electrolyte Membrane

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.

3

Engineered for Low-Concentration Operation

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.
