Diesel Applications
COBALT H₂ technology is designed for diesel engines used in commercial transport, industrial operations, agriculture and specialized equipment.
The HOD (Hydroxy On Demand) system generates a hydrogen-oxygen gas mixture on demand while the engine is running and supplies it to the engine’s air intake system. Potential changes in fuel consumption and operating performance must be evaluated against a documented baseline; no outcome is guaranteed.
Each application is evaluated according to engine specifications, operating conditions, load profile and installation requirements.

THE STARTING POINT / OPERATING DATA
Different applications. Comparable evidence.
For every application, start with engine details, equipment quantity, location and maintenance condition. The operating data below helps define a meaningful baseline. Incomplete records are a starting point for discussion—not a reason to invent an estimate.

Operating context: Distance, payload and typical routes
Baseline to review: Litres per distance under comparable conditions
Agriculture
Operating context: Task, seasonal hours and workload
Baseline to review: Fuel use by operating hour or representative task

Oil & Gas
Operating context: Running hours, documented loads and continuous or variable duty cycles.
Baseline to review: Fuel use at comparable operating conditions, supported by generator-level fuel records where available.
Industrial Diesel Equipment
Operating context: driven machinery, workload, engine hours and installation environment. Baseline to review: documented fuel use at comparable loads and duty cycles, with maintenance records where available.
Railway Engines
Operating context: locomotive configuration, traction load, running hours and duty cycle. Baseline to review: fuel use under comparable railway operating conditions and application-specific installation requirements.
Any fuel savings, cost or emissions outcome must be verified through an agreed testing method. No application is assumed to deliver a guaranteed result.
INDUSTRY QUESTIONS
A practical assessment starts with clear answers.
Can a mixed fleet be evaluated together?
How are seasonal agricultural workloads compared?
What data matters most for diesel generators?
What additional review is needed for marine applications?
Can mining equipment be assessed in demanding site conditions?
What if our fuel records are incomplete?
Are fuel savings guaranteed for any industry?
How are remote oil and gas generator installations assessed?
For an individual assessment, prepare the equipment type, engine make and model, displacement and power, year of manufacture, operating hours or mileage, typical workload, fuel consumption, installation environment and available operating records. Incomplete records can be discussed; they are not a reason to invent an estimate.
