Lower Diesel Use and Carbon Intensity Using Your Existing Fleet
ESSNA™’s hydrogen diesel blending system retrofits to existing heavy-duty engines to reduce diesel consumption and carbon intensity without fleet replacement.
Hydrogen is blended into the combustion process for a cleaner, more efficient burn — delivering immediate impact and providing a practical bridge toward lower-carbon fleet operations.
Designed for Heavy-Duty Fleet Operations
ESSNA™’s hydrogen-diesel blending service is intended for organizations operating diesel-powered vehicles or equipment where fuel consumption and carbon intensity are operational priorities.
Long-haul and regional trucking fleets
Heavy-duty industrial and construction equipment
Energy and resource operations
Fleets under ESG or carbon-intensity pressure
Hydrogen–Diesel Blending at a System Level
ESSNA™’s hydrogen-diesel blending system integrates with existing heavy-duty engines to introduce hydrogen into the combustion process in a controlled, autonomous manner — without replacing engines or altering normal vehicle operation.
Onboard Generation
Hydrogen is generated on board as part of ESSNA™’s turnkey blending system while the vehicle is in operation, eliminating the need for external refuelling or new infrastructure.
Precision Blending
The H59-D™ autonomous blending module injects hydrogen into the diesel combustion process using precision controls, supplementing diesel without altering engine design or performance.
Cleaner Combustion
Blended hydrogen enables a cleaner, more efficient diesel burn, delivering measurable reductions in diesel consumption and carbon intensity while maintaining engine uptime.
Autonomous Operation
The system operates autonomously during normal driving conditions, requiring no driver input and no changes to existing vehicle operation or workflows.

Retrofit-based approach designed to integrate with current diesel engines and equipment, extending asset life.
Achieve measurable reductions in carbon intensity as part of a practical, near-term decarbonization pathway.
Deliver results without long transition timelines, new vehicle procurement, or infrastructure overhauls.
Operate under normal driving conditions while maintaining engine performance and fleet availability.
Reduce diesel use across existing heavy-duty vehicles by supplementing combustion with hydrogen during normal operation.
Our Process
ESSNA™ manages deployment end-to-end to ensure the hydrogen-diesel blending system integrates into existing vehicles and operations with minimal disruption.
Get Started1. Fleet Assessment
ESSNA™ reviews vehicle types, duty cycles, and operating conditions to confirm suitability.
2. Retrofit Installation
The blending system is installed on existing vehicles by ESSNA™ without requiring engine replacement.
Commissioning & Validation
Systems are commissioned and validated to ensure proper operation before entering service.
4. Ongoing Operation
ESSNA™ manages system operation and performance as part of the ongoing service.

FAQ's
No. Our hydrogen-diesel blend works with your existing diesel engines, so there’s no need to invest in new vehicles to start reducing emissions and fuel costs.
Nothing upfront. ESSNA™ covers the cost of installation and setup. You only pay for the hydrogen fuel you use.
Our units generate hydrogen using electrolysis or natural gas reforming, depending on your site setup. The system is fully self-contained and optimized for fleet yard operations.
Our system includes 24-hour fuel reserve storage and real-time monitoring — we guarantee uptime and handle all maintenance.
Yes. Using a hydrogen-diesel blend or switching to hydrogen can significantly lower your fleet's carbon intensity, making you eligible for government incentives or carbon credits.
