With the Transformative Power of Hydrogen on Demand
Diesel: The Workhorse Of Our Global Economy
Diesel is the workhorse of our global economy, packing more joules of energy per kilogram than any other carbon-based fuel. It moves more goods for less, so fleet operators make more money. That’s why 90% of all global goods are transported by diesel.
However, diesel exhaust accounts for 35% of global greenhouse gas emissions, putting fleet operators under increasing pressure to become cleaner and to transition to zero-emission fuel.

The Practical Pathway To Cleaner,
More Efficient Operations
Hydrogen On Demand Technologies is the worldwide original equipment manufacturer (OEM) of Diesel Hydrogen Assist Technology (D-HAT™) that equips diesel fleet operators with a practical pathway to cleaner, more efficient operations. D-HAT is a certified and warrantied aftermarket onboard hydrogen generator. Through electrolysis, using our patented PEM cell technology, it separates distilled water into hydrogen and oxygen, producing pure hydrogen on demand. The hydrogen is infused into the fuel-air mixture via the air intake of any large diesel engine’s combustion chamber to enhance the fuel burn.
By delivering the optimum amount of hydrogen into your engine at the right time, D-HAT increases its combustion efficiency from approximately 70% to 95% or higher. This not only makes your equipment run with greater fuel-efficiency and dramatically reduced emissions, but it also delivers significantly improved fleet operations.

Benefits That Add Up To A Triple Bottom Line Improvement
For diesel fleet operators up against razor-thin margins, D-HAT hydrogen generators are an effective way to contribute to operational efficiency and increased profitability. By squeezing out more energy per combustion event, D-HAT is proven to increase fuel mileage, decrease engine maintenance and reduce emissions, delivering a triple bottom line improvement to your operations.
