OptiFuel Systems Introduces New Zero-Emission Locomotives
OptiFuel Systems has unveiled an innovative line of Total-Zero™ Diesel Hybrid and Total-Zero™ Diesel-RNG Dual Fuel Hybrid Series locomotives. Production and delivery of these groundbreaking systems are expected by 2026, with options available for retrofitting onto existing switchers or line haul platforms.
Transforming Locomotive Power and Emissions
The newly developed locomotives are designed for optimal continuous and peak power while maximizing fuel efficiency and uptime. These advancements allow railroads to meet stringent emissions standards and enhance reliability, safety, and profitability. By minimizing the infrastructural costs and operational constraints that typically accompany zero-emission technology, the solution promotes a seamless transition while maintaining diesel as the primary fuel source.
Key Features of Total-Zero™ Diesel-RNG Dual Fuel Series
One standout feature of the dual fuel series is its ability to utilize up to 33% renewable natural gas (RNG), significantly contributing to greenhouse gas (GHG) elimination alongside reductions in NOx and particulate matter (PM). This model allows railroads to adjust GHG emissions in real-time through flexible blending of RNG and diesel. Such adaptability is crucial for Class 1 railroads striving to meet science-based targets for GHG reductions, making the expected performance of the Dual Fuel Series particularly promising:
- NOx emissions: <0.035 to >0.02 g/bhp-hr
- PM emissions: <0.005 g/bhp-hr
- GHG emissions: Zero (0) gCO2eq/MJ
These criteria emissions demonstrate an impressive 88% cleaner performance compared to the initially proposed CARB Tier 5 standards.
Significant Advantages for Railroads
OptiFuel's Total-Zero™ Diesel Series locomotives offer numerous advantages, including:
- The ability to travel up to 1,500 miles between refuels without needing a tender
- A projected reduction of diesel usage by up to 20% compared to Tier 4 Diesel
- Robust power backup, ensuring reliability with a total peak output of 6,000 hp
- AC traction and regenerative braking capabilities for consistent performance
- A lifespan of 30 years, designed for easy upgrading and adaptation for future technologies
- 95% operational uptime, exceeding the diesel locomotive industry average of 81%
- Quick module replacements minimize disruption, allowing a one-hour engine change
- Lower lifetime operating and maintenance costs
Elimination of the Fuel Tender
According to OptiFuel’s CEO, Scott Myers, the new Diesel-RNG dual fuel system revolutionizes operations by removing the necessity of a fuel tender for zero-emission line haul services. This elimination reduces risk and costs linked to infrastructure that depends on hazardous materials. Given recent concerns about safety in light of industrial accidents, he believes that regulators will advocate for such innovations over traditional options like hydrogen or lithium battery tenders in urban areas.
Cost-efficient Refueling Infrastructure
The dual fuel system also enhances the efficiency of refueling operations. Each RNG dispenser can refill locomotives with an impressive 2,500 diesel gallon equivalents (DGE) of RNG every 30 minutes, equating to the daily replenishment of 48 locomotives at a refueling site. Establishing the necessary infrastructure to support this model is estimated at approximately $1.2 billion, a significantly more economical option compared to transitioning to hydrogen or electric systems.
Commitment to Reliability and Safety
OptiFuel Systems has a history of success in alternative fuel solutions. The company has pioneered various dual fuel power systems, leading the industry in integrating RNG and hydrogen into locomotive technologies. Their extensive effort culminated in FRA concurrence for a CNG/RNG onboard storage system in freight locomotives, alongside the establishment of the world’s inaugural CNG/RNG fuel station for locomotives.
This strategic innovation in the rail sector allows dual fuel locomotives to refuel using diesel and CNG simultaneously. With its modular locomotive and fuel storage designs, OptiFuel promotes agility in integrating components and testing new solutions while ensuring safety and efficacy.
