The presentation will cover selected advanced process technologies for production of renewable low-carbon fuels, including hydrogen, methanol, ammonia and DME for use in modern propulsion systems. Several commercially proven Feed & Waste Conversion Systems (4-6) to produce the low carbon fuels will be identified and characterized regarding key technical & commercial attributes, including relative economics, efficiency and raw material use of each. Additionally, an analysis of the various fuels for current and future applications with propulsion systems, including land transport, marine, aircraft and space vehicles will be addressed.
