Case Study

2023 Locomotive Client Trial

The D-HAT™ 6000 delivered a 24% fuel consumption reduction.

Reduce Fuel Consumption

Reduce Emissions

Reduce Maintenance Costs

In 2023, we tested our D-HAT™ technology on a large locomotive diesel engine in a normal operations study. The first field tested engine was the 2 stroke EMD 645/GP38.

The D-HAT™ 6000 delivered an average of 24% fuel consumption reduction. The pilot study also delivered a massive reduction in green house gas and particulate matter emissions.

After 6 months of use, you can see the difference our Diesel-Hydrogen Assist Technology (D-HAT™) made on this engine.

Locomotive D-HAT™ 6000 Test 2023 Trial: 2 Stroke Diesel EMD 645/GP38

During the 100-day normal operations study, our D-HAT™ 6000 on-board hydrogen-infusion system led to fuel usage decreases of 10 to 30%, with an average 24% reduction.

In addition to the fuel savings, the study also found a reduction in harmful exhaust emissions. CO2 (Carbon Dioxide) up to 24%, NOx (Nitrogen Oxides) up to 40%, CO (Carbon Monoxide) up to 89%, THC (Total Hydrocarbons) up to 73%.

Along with prolonged engine life, the D-HAT™ 6000 system significantly reduces the frequency of engine maintenance, such as diesel particulate filter (if required) maintenance and replacement.

HoD Tec D-HAT™ 6000 units deliver an off-the-shelf, fleet-wide solution for dramatic reductions in fuel consumption and engine emissions, with the lowest cost of transition of any alternative optimization ROI.

D-HAT™ 6000 systems afford a no-risk, significant increase in operational efficiency. With D-HAT™, fuel and maintenance savings per diesel engine are often in excess of 20% per year, based on average operating hours. The ROI is typically only 12 to 18 months, while lease to buy options usually deliver immediate positive impact to the customer’s bottom line.
