The global push for cleaner energy and reduced emissions has put industries that rely heavily on diesel engines under significant pressure to adopt greener technologies. Diesel engines, while powerful and essential for heavy-duty applications, are notorious for their high emissions of greenhouse gases and pollutants. Transitioning to cleaner solutions, however, can be costly and technically challenging, especially for industries that rely on diesel’s durability and power.

Enter Hydrogen on Demand technology, specifically Diesel-Hydrogen Assist Technology (D-HAT™), a revolutionary approach that combines the power of hydrogen with the reliability of diesel engines. By injecting hydrogen into the combustion process, D-HAT™ enhances diesel efficiency, reduces emissions, and improves engine performance—all without the need for major engine modifications or storage of hydrogen. This blog explores how Hydrogen on Demand works, why it’s a safe and efficient solution, and how it paves the way for cleaner diesel engines.

The Need for Cleaner Diesel Solutions

Diesel engines are critical to the global economy, powering industries like transportation, shipping, construction, mining, and agriculture. Diesel’s high energy density makes it the go-to fuel for heavy-duty applications, enabling vehicles and machinery to haul large loads over long distances or operate continuously for extended periods. However, the environmental drawbacks of diesel are significant:

• High emissions: Diesel engines emit large amounts of carbon dioxide (CO2), nitrogen oxides (NOx), particulate matter (PM), and other pollutants that contribute to air pollution and climate change.
• Fuel inefficiency: Traditional diesel engines achieve only about 70% combustion efficiency, meaning a significant portion of the fuel remains unburned and wasted.
• Carbon buildup: Incomplete combustion leaves behind carbon deposits inside the engine, reducing performance and increasing maintenance costs.

As industries face tightening environmental regulations and rising fuel costs, finding ways to improve diesel efficiency and reduce emissions is critical for maintaining profitability and sustainability. Hydrogen on Demand technology offers a promising solution.

What is Hydrogen on Demand?

Hydrogen on Demand refers to the real-time generation and injection of hydrogen into a diesel engine’s air intake system, where it mixes with diesel fuel to enhance combustion. Unlike traditional hydrogen fuel cell technologies, which require hydrogen to be stored under pressure in large tanks, Hydrogen on Demand systems like D-HAT™ produce hydrogen on-site and on-demand using an electrolysis process.

Key Components of Hydrogen on Demand Technology:

1. Proton Exchange Membrane (PEM) Cell: The core of the D-HAT™ system, the PEM cell generates pure hydrogen gas by splitting distilled water into hydrogen and oxygen using electricity from the engine’s alternator. This hydrogen is produced only when the engine is running, ensuring no hydrogen is stored onboard.
2. Hydrogen Injection: The hydrogen gas is injected directly into the engine’s air intake manifold, where it mixes with the diesel fuel. Hydrogen burns faster and more completely than diesel, promoting a more efficient combustion process.
3. Real-Time Hydrogen Generation: The D-HAT™ system produces hydrogen in real time, ensuring that hydrogen is only generated as needed, making it both safe and efficient.

The ability to produce hydrogen on-site and on-demand eliminates the need for high-pressure hydrogen storage tanks, which are often costly and come with safety risks. This makes Hydrogen on Demand a more practical and scalable solution for diesel engines.

How Hydrogen on Demand Improves Diesel Engine Efficiency

The addition of hydrogen into the diesel combustion process enhances fuel efficiency in several key ways:

• Faster combustion: Hydrogen burns around 10 times faster than diesel fuel. By injecting hydrogen into the engine, the diesel fuel ignites and burns more quickly and completely, improving overall combustion efficiency.
• More complete combustion: Traditional diesel engines waste a significant portion of the fuel due to incomplete combustion, resulting in unburned hydrocarbons and carbon deposits. With hydrogen assisting the burn, D-HAT™ improves combustion efficiency from around 70% to as high as 93%.
• Increased torque and power: By burning fuel more completely, hydrogen-assisted combustion delivers greater power output per combustion cycle, resulting in increased torque and improved performance without requiring additional fuel.

Fuel Savings and Reduced Emissions

One of the most immediate benefits of Hydrogen on Demand technology is fuel savings. By optimizing the combustion process, D-HAT™ can reduce fuel consumption by up to 10%, allowing fleet operators to go further on less fuel. These savings are especially significant for industries that rely on diesel engines for heavy-duty applications, where fuel costs represent a major portion of operating expenses.

Moreover, the cleaner, more efficient burn enabled by hydrogen injection leads to a dramatic reduction in harmful emissions, including:

• CO2 (Carbon Dioxide): A primary contributor to global warming, CO2 emissions are reduced as less diesel is burned per mile traveled.
• NOx (Nitrogen Oxides): Hydrogen reduces the peak combustion temperature, which helps limit the formation of NOx, a major pollutant responsible for smog and acid rain.
• Particulate Matter (PM): The more complete combustion process reduces the production of soot and particulate matter, leading to cleaner exhaust and improved air quality.

The Safety of Hydrogen on Demand

One of the key concerns with any hydrogen-based technology is safety, particularly the storage and handling of hydrogen gas. Hydrogen, while extremely energy-efficient, is also highly flammable, and traditional hydrogen fuel cell systems require large tanks to store the gas under high pressure. This creates significant safety challenges, particularly in transportation and industrial settings.

Hydrogen on Demand technology addresses these concerns by producing hydrogen only as needed. The D-HAT™ system generates hydrogen on-site using water and electricity from the engine’s alternator, eliminating the need for hydrogen storage. Here’s why Hydrogen on Demand is a safer alternative:

• No hydrogen storage: Because hydrogen is produced in real time and immediately injected into the engine, there is no need for tanks or high-pressure storage. This minimizes the risk of leaks or explosions.
• Low hydrogen volume: The amount of hydrogen produced by the D-HAT™ system is small—typically just a few liters per minute—making it safer to handle and easier to control.
• Fully consumed hydrogen: All hydrogen produced by the system is consumed in the combustion process, ensuring there is no residual hydrogen left in the engine or exhaust system.

With its real-time generation and direct injection, Hydrogen on Demand offers a safe, controlled method of improving diesel engine performance without introducing the risks associated with hydrogen storage.

Why Hydrogen on Demand is Ideal for Diesel Engines

For industries that rely on diesel engines, switching to cleaner alternatives like electric or fuel cell-powered engines may not be practical or affordable in the short term. Diesel engines have decades of proven reliability, particularly in applications requiring heavy loads and long operating hours. Hydrogen on Demand technology allows diesel engines to continue delivering the performance they are known for, while significantly reducing emissions and fuel consumption.

Key Advantages for Fleet Operators:

1. No Major Engine Modifications: The D-HAT™ system can be installed on most diesel engines with minimal modifications. Unlike other clean technologies that require significant changes to the engine or fuel system, D-HAT™ integrates seamlessly with existing diesel engines, making it a cost-effective option for fleet operators.
2. Lower Operating Costs: By improving fuel efficiency and reducing maintenance needs, Hydrogen on Demand can deliver immediate cost savings. Fleet operators can save up to 10% on fuel costs and reduce maintenance expenses by cutting carbon buildup inside the engine.
3. Compliance with Emissions Standards: With stricter environmental regulations being enforced worldwide, Hydrogen on Demand helps diesel engines meet or exceed EPA and CARB emissions standards without sacrificing power or reliability. This ensures that fleet operators remain compliant while reducing their environmental footprint.
