OptiFuel Systems is a solution provider designing and manufacturing zero emission products and services in the hard-to-abate transportation and industrial markets, specifically in rail, marine and power generation.

An industry choking for change.

If the railroads want to eliminate their carbon footprint, they must decarbonize line haul locomotives that emit 85% of all criteria and greenhouse gas emissions.

38,000

Diesel-powered locomotives in the U.S. alone

4.2 billion

gallons of diesel fuel burned by U.S. trains every year

43 million

tons of greenhouse gas emissions produced annually in the U.S.

Over 50%

of diesel locomotives are beyond end-of-life, with many over 50 years old

“I believe the decarbonizing of the global economy is going to create the greatest investment opportunity of our lifetime…The next 1,000 unicorns won’t be search engines or social media companies, they’ll be sustainable, scalable innovators — startups that help the world decarbonize and make the energy transition affordable for all consumers.”

Larry Fink, CEO, Blackrock

Our Solutions

OptiFuel delivers deep impact.

We design and build locomotives powered by renewable natural gas (RNG) and hydrogen, with a mission to decarbonize the world’s 124,000 diesel locomotives by 2050.



Cost-effective modular deployment drives value — making it efficient to produce, operate, and maintain.



Reduces fuel usage by an estimated 20-30% over diesel, saving US railroads approximately $1.7 billion in annual fuel expense.



Eliminates 925,000 short tons of annual criteria emissions and 43 million metric tons of annual CO2 emissions in the US.
