Discover LeefH2™ Technology in Action

How It Works

The LeefH2 hydrogen enhanced combustion cycle how trace on demand hydrogen accelerates flame propagation.

Combustion Engines: Environmental Impact

Why clean combustion is critical for industrial, trucking, and marine logistics in the coming decades.

Core LeefH2™ Technology

Efficient PEM Hydrolysis

Splits pure/distilled water into highly pure hydrogen (99.99%) and oxygen on demand.

Safe & Dry Operation

Generates gas instantly as needed. No chemical storage, pressurized hydrogen tanks, or risk of deflation.

Chemical-Free

Functions strictly on pure water. Eliminates highly corrosive strong acids or alkaline (KOH/NaOH) additives.

OBD-II Smart Control

High precision 7nm U.S. control chip integrates seamlessly with the engine’s onboard OBD port.

Microsecond Ignition Algorithm

Reads engine injection, ignition, and shift timing to release trace hydrogen at the precise microsecond.

Ultra-Low Draw

Minimizes battery load to just 2W for computer processing lowering thermal and electrical stress.
