H59-D Autonomous™ Features

Multi-Engine Support

Connects and manages hydrogen blending across multiple diesel engines from a single system.

Autonomous Blending Control

Automatically adjusts hydrogen flow based on engine load and operating conditions.

Engine-Safe Operation

Designed to operate within engine-safe parameters without requiring engine replacement or modification.

Low Impact Integration

Installs alongside existing diesel engines with minimal downtime or infrastructure changes.

Advanced Safety Systems

Integrated leak detection, pressure controls, and automatic shutdown protocols.

Remote Monitoring & Control

Real-time system visibility, performance tracking, and adjustments from anywhere.

Applications

Tractor Trucks & Fleet Operations

H59-D Autonomous™ enables hydrogen–diesel blending on existing tractor trucks to reduce fuel consumption and emissions without taking vehicles out of service or requiring fleet replacement.

Drilling & Industrial Diesel Engines

H59-D Autonomous™ supports hydrogen–diesel blending for drilling rigs and industrial engines, delivering cleaner combustion and reduced carbon intensity without disrupting critical operations.

Mining & Heavy Construction Equipment

For mining and heavy construction, H59-D Autonomous™ integrates directly with large diesel engines to improve combustion efficiency and lower operating costs while maintaining full-duty cycle performance.

Generators & Stationary Power

For prime and backup power generation, H59-D Autonomous™ reduces diesel dependency and emissions while preserving reliability, runtime, and existing generator infrastructure.
