What you frame in your request resists some simple conclusions re: the purpose of your paper. I get that you are either trying a clean sheet proposal, or are seeking to collect data from work that has already been done. Hundreds of times.
All design flows from a goal of some description.
Is your goal to capture strictly a "Green Design"? Or does it also have something to do with SFC, meaning fiscal drivers, and requisite financial limits??
Aviation is always a compromise of hundreds of "Important" considerations. If you want semi clean sheet, PM Keesje. He has some remarkable concepts going on at any given moment.
If you want Fuel specifics re: design engineering of Turbine powerplants, PM Turbine D. Fuel tankering and logistics: Pinkman.
Your first task, and perhaps the simplest, is to index your two salient parameters in your proposal.
CO2, and SFC. Where you position the one or the other in your Title drives the discussion, No??
Oxygenated Fuels, there's the ticket..........
best of luck,
