BMWi project ”Solare Kraftstoffe“ - Technical Fuel Assessment

Sustainably produced drop-in fuels offer great potential for reducing greenhouse gases in the transport sector, and the possibility of using existing infrastructures facilitates a quick implementation into the transportation system. Hence, drop-in fuels are the only option that can address the existing vehicle fleet. Nevertheless, renewable fuels have to be economically competitive and comply with technical specifications. An intriguing concept are solar-thermal produced renewable drop-in fuel components for gasoline engine with time horizon up to 2030. The techno-economic consideration and the studies of technical fuel assessment for selected solar fuels are activities embedded in the BMWi funded project “Solare Kraftstoffe”. The goal is the identification of optimized, low-pollutant, synthetic fuel components as well as the evaluation of the engine performance including pollutant behavior. Therefore, chemical analytic experiments, engine tests and the development of a digital platform for the model-based assessment and optimization of fuels are carried out and presented here.
