Heavy-duty vehicles play a critical role in transportation, construction, and industry, but they are also a significant source of greenhouse gas emissions. Many fleets rely on diesel equipment with long lifespans, and replacing these vehicles with low-emission alternatives can be costly and slow, creating a barrier to immediate emissions reductions.
Diesel Tech Industries is addressing this challenge through its Guardian Hydrogen Diesel System, a retrofit technology that allows existing diesel engines to operate using a blend of hydrogen and diesel. The system integrates advanced controls and safety features, enabling fleets to reduce diesel use while maintaining performance and reliability in demanding operating conditions.
Testing has shown diesel consumption reductions of up to 60 percent, alongside significant decreases in greenhouse gas emissions and nitrogen oxides, improving air quality and reducing the environmental impact of heavy-duty transportation.
