“…NH 4 Methane,p roduced using the Sabatier reaction, [71] is the simplest carbon-based fuel (i.e., the smallest molecule with the smallest functional groups). Thesimplest oxidant variant of methane,m ethanol, is also aw ell-studied and important alternative fuel, and it is the simplest carbon-based fuel that is liquid at standard conditions.F urthermore,D ME is the simplest ether derived from MeOH.…”
