Fleets
Slash Harmful Engine Emissions & Reduce Costs Faster Than Any Other Available Technology
ClearFlame is empowering fleets and class 8 semi-trucks with a new engine technology that unlocks heavy-duty diesel engines to run on 100% renewable plant-based fuels.

Now you can reduce engine emissions and save money, all without compromising engine performance.
Break free from diesel fuel price swings and continue saving. When implemented in long-haul Class 8 trucks, ClearFlame’s technology has the lowest Total Cost of Ownership (TCO) of any current technologies, including diesel, natural gas, electric, and hydrogen, and is more rapidly implemented than any available alternative.
By the Numbers
ClearFlame’s heavy-duty emissions reductions and savings
160,000
Pounds of carbon emissions removed from the atmosphere each year, on average
$32,000
Annual fuel cost savings for one truck running 100K miles per year
3,300
Equivalent number of trees planted each year
300
Annual reduction in barrels of fossil fuels
We’re driving towards a goal of 1 million miles across America.
ClearFlame’s truck, with an engine modified with our patented technology, is making stops across the United States. It’s the only class 8 truck to run on 100% clean, renewable ethanol fuel, without any additives and without any diesel fuel.

Keep on trucking
You don’t need to completely disrupt your operations to meet your sustainability goals. Keep leveraging your existing liquid fueling and maintenance infrastructure. Any mechanic who can service a diesel engine today can service one with our technology.
Enjoy the Drive
ClearFlame modifies engines to break free from diesel fuel, without changing everything you love about compression-ignition engines. Enjoy the same power, run times and torque curve you expect.
A sustainability win for hard-to-electrify, heavy-duty transportation
ClearFlame provides scalable, measurable emissions reductions and air quality benefits, quickly reducing harmful greenhouse gas (GHG) and tailpipe emissions. Trucks equipped with ClearFlame’s technology reduce CO2 emissions significantly while lowering air quality emissions – particulate matter (soot) and nitrogen oxide (smog) – to nearly zero levels.
How Does ClearFlame Compare to Other Engine Technology for Fleets?
Other Technology | The Challenge | The ClearFlame Solution |
---|---|---|
Electric battery power | Electric batteries require charging stations in different locations than drivers are used to. Run times may be reduced. | ClearFlame lets you keep the same refueling infrastructure and the same reliable run times. 100% renewable ethanol is already widely produced and distributed. |
Electric battery power | Electric battery engines are heavy and may require different maintenance. | ClearFlame lets you keep your same engines and diesel mechanics. |
Hydrogen | Challenging and costly to store and dispense, especially in mobile applications. | ClearFlame lets you keep your same refueling infrastructure. Drivers can refuel as they normally would. |
Spark-Ignited Engines Using Alternative Fuels | Sacrifice efficiency and torque. | ClearFlame maintains all the characteristics of an internal combustion, compression ignition diesel engine, including scaling to any engine size or bore diameter. |
