Guardian Hydrogen
Diesel System

Reduce your carbon footprint with your existing fleet today!

Cleans Emissions Systems

Hydrogen Acts as a catalyst much like the DEF fluid we use today. The Cleaner combustion that hydrogen creates also actively reduces the amount of unburnt fuel entering the emission system.

Cost Effective Solution

Allows you to retro fit the existing tier 4 diesel engines in your fleet, thus reducing your GHGs.

Retrofit For
Existing Engines

The Guardian Hydrogen Diesel system is very non-invasive to the factory engine and allows for you to retain all factory components of the engine and emission systems.

Injecting Hydrogen Intelligently

As the world transitions to low-carbon energy sources, the headwinds facing the trucking industry are numerous and significant. At the top of the list are the regulations to lower the emission of CO2, NOx, SOx, and Particulate Matter. In addition to the lower emission requirements, fleets must also ensure they maximize their existing fleet capital before looking at replacing either engines or trucks. By ensuring low emissions and high capital efficiency, innovative and environmentally conscious trucking fleets can build a competitive advantage during bidding and procurement processes with their clients.
