H59-D Autonomous™ Hydrogen–Diesel Blending for Heavy Equipment and Earthwork Environments
Cut Operating Costs. Lower Carbon Intensity. Hydrogen Supplied. No Capital Risk.
Heavy equipment and earthworks operations rely on diesel for a simple reason: it works. It delivers the power, reliability, and flexibility required in demanding environments. At the same time, diesel represents one of the largest controllable operating costs on site and a major contributor to carbon intensity.
Hydrogen–diesel blending offers a practical way to address both challenges—without replacing engines, altering operating practices, or requiring upfront capital investment.
For operators focused on performance, cost control, and near-term carbon-intensity improvement, ESSNA™ blending via the H59-D Autonomous™ system provides a commercially deployable solution built specifically for heavy-duty applications.
Improving Diesel Performance Without Replacing Diesel
Hydrogen–diesel blending is not a fuel switch. It is a combustion-efficiency solution maintaining your operational model with a number of benefits. The outcome is straightforward: less diesel is required to perform the same work. This efficiency gain directly reduces operating costs while lowering carbon intensity per operating hour.
ESSNA™ systems are engineered to deliver this improvement consistently in real operating conditions—not just under ideal test scenarios.
Guaranteed Diesel Reduction and Measurable Results
ESSNA™ blending solutions are designed around outcomes that matter to operators. The system delivers a minimum guaranteed 10% reduction in diesel consumption, achieved through improved combustion efficiency rather than fuel displacement. This guarantee is critical. It ensures operators are not paying for theoretical gains or best-case scenarios, but for measurable, repeatable performance improvements that translate directly into cost savings.
In addition to reduced diesel consumption, operators benefit from smoother engine operation under load and a more consistent combustion process, which supports overall equipment performance.
No Upfront Capital Expenditure. Hydrogen Is Supplied.
One of the most significant barriers to hydrogen adoption in heavy equipment environments has been capital risk. ESSNA™ eliminates this barrier entirely.
The blending solution requires no upfront capital investment from the operator. Hydrogen is supplied by ESSNA™ as part of the service removing the need for storage tanks, delivery logistics, or hydrogen supply contracts.
This approach shifts blending from a capital decision to an operating decision. Operators avoid long payback periods and infrastructure commitments while gaining immediate access to hydrogen-enabled efficiency improvements.
Designed for Heavy Equipment and Earthworks Environments
ESSNA™ blending systems are purpose-built for heavy-duty use. They are compact, robust, and designed to operate reliably in environments characterized by dust, vibration, temperature variation, and sustained high loads.
The systems integrate with existing diesel equipment with minimal disruption and include modern safety features such as automated shutdowns, leak detection, and intelligent control logic. This ensures safe, reliable operation across both on-road and off-road applications.
As a result, hydrogen–diesel blending is suitable for a wide range of use cases, including earthmoving fleets, construction equipment, mining and quarry operations, and heavy generators operating in remote or challenging conditions.
Immediate Value, Not a Long-Term Wait
For many operators, full fuel switching or equipment replacement is neither practical nor economically justified in the near term. Hydrogen–diesel blending offers an immediate, low-risk pathway to improved efficiency and reduced carbon intensity using existing assets.
By combining guaranteed diesel reduction, supplied hydrogen, and a no-CapEx deployment model, ESSNA™ enables operators to capture tangible benefits today while maintaining flexibility for future energy transitions.
A Practical Step Toward Lower Carbon Intensity
Hydrogen–diesel blending is no longer an experimental concept or a niche technology. When implemented with the right system design and commercial model, it becomes a practical tool for reducing diesel consumption, lowering carbon intensity, and improving operating economics.
Through its blending solutions and broader Energy Modelling and Advanced Planning™ (EMAP™) platform, ESSNA™ helps operators quantify performance improvements, manage energy risk, and make informed decisions about how and when to adopt hydrogen across their operations.
For heavy equipment and earthworks operators, hydrogen–diesel blending represents one of the most immediate and commercially viable efficiency gains available today.
