OptiFuel Systems to begin testing RNG locomotive prototypes in 2025

In South Carolina, OptiFuel Systems announced that it will begin testing a prototype 5600 hp Total-Zero Renewable Natural Gas (RNG) Line Haul Locomotive and 2500 hp Total-Zero Powered Tender with 7,500 DGE (diesel gallon equivalent) capacity, in January 2025. The RNG-powered line haul locomotive produces 5100 hp of continuous power from zero emission Cummins RNG engines using OptiFuel’s Quick-Power technology with a peak power of 5600 hp with the standard LFP battery pack. Focused on sustainability, OptiFuel’s near-term, low risk, affordable Total-Zero RNG-Electric Line Haul Locomotive will have ZERO Well-to-Wheel (WTW) nitrogen oxides (NOx) and particulate matter (PM) criteria emissions and Negative Carbon Intensity (CI) while simultaneously improving fuel cost and operating range by 25%.
