Technical Fuel Assessment
We focus on the carbon-neutral utilization of novel chemical energy carriers (“fuels”) for the reconversion to electric power, in ground transportation or in aviation. The overall goals are the assessment and optimization of the synthesized fuels from the various production paths considered in the Subtopic Power-based Fuels and Chemicals. For a global assessment and optimization of these fuels, it is key to determine the technical performance, pollutant reduction potential, drop-in capability (compatibility), availability and cost. Finally, an iterative co-optimization of fuel, combustion engine technology, and subsequent exhaust gas treatment will synergistically exploit the full potential of the fuel utilization system.
The technical fuel assessment with regard to “real world application scenarios” is of major importance to deliver feedback information to the fuel synthesis topics as fuel composition impacts combustion and emission behavior significantly. Real driving emission (RDE) legislation and low-temperature testing conditions also bring further hallenges with regard to both severe engine pollutant formation conditions and highly transient exhaust gas conditions for exhaust gas aftertreatment devices.
