Rolls-Royce Power Systems has completed a laboratory fuel assessment of INERATEC’s synthetic MATERA e-Diesel. This joint technical evaluation examines the compatibility of renewable synthetic fuels within digital infrastructure and mission-critical backup power sectors, aiming to substitute fossil diesel in stationary generator fleets.
Technical challenges in fuel transition
Data centers, hospitals, and transport hubs rely on stationary diesel generators to maintain operational continuity during power outages. Transitioning these systems to lower-carbon alternatives introduces substantial engineering challenges regarding fuel stability, system reliability, and component degradation.
While complete system replacement involves high capital expenditure, utilizing drop-in synthetic fuels requires precise verification of chemical and physical properties to prevent mechanical failures. To address this, the cooperation leverages the fuel synthesis technology of INERATEC and the powertrain testing infrastructure of Rolls-Royce Power Systems to establish an empirical baseline for synthetic fuel performance.
Evaluation parameters and technical division
The laboratory assessment focused on specific fuel quality, lubricity, and material compatibility parameters. The technical properties were benchmarked against the EN 15940 standard for paraffinic diesel fuels and the proprietary mtu Fluids and Lubricants Specification A001061/46.
The division of technical responsibilities during this phase includes:
- INERATEC: Supplied the synthetic fuel produced via modular chemical synthesis, utilizing renewable hydrogen and carbon dioxide to formulate the hydrocarbon chains.
- Rolls-Royce Power Systems: Conducted the analytical laboratory testing, focusing on elastomer compatibility, chemical degradation tracking, and physical property indexing.
The laboratory testing yielded specific quantifiable parameters:
- Sulphur Content: Measured below 5 mg/kg, falling beneath the maximum thresholds defined by the EN 15940 standard.
- Energy Density: The net calorific value of the synthetic fuel was recorded at approximately 44.0 MJ/kg.
- Storage Stability: The medium remained stable over a minimum evaluation window of three months, showing no critical variance in neutralization number, oxidation stability, or lubricity under controlled laboratory storage conditions.
- Material Compatibility: Testing of exposed elastomer parameters revealed no significant physical or structural differences when compared to conventional petroleum-based reference fuels.
Operational deployment and scope
The current phase of the cooperation remains constrained to laboratory-level verification of chemical mechanics. Engine performance, exhaust emissions behavior, and application-specific operational variables were not included in this testing scope.
The integration of the fuel into existing critical infrastructure networks is designed as a drop-in solution, meaning it utilizes existing storage tanks and fuel delivery lines without modification. However, deployment in specific engine applications remains subject to further series-specific validation, operating conditions, and official fuel releases by the manufacturer. Long-term chemical stability analyses are ongoing to determine extended aging characteristics before field implementation begins.
