Gasoline-ethanol-methanol Tri-fuel Vehicle Development And Its Role In

ABSTRACT

Proposed long-term options for de-carbonizing transport are assessed. Various

shortcomings of electrification or molecular hydrogen as an energy carrier are discussed

which may prevent their widespread adoption. The development of a Tri-Fuel vehicle,

capable of operating on any combination of gasoline, ethanol, and methanol, using a

single fuel system is described, demonstrating that compatible, affordable transport can

be developed, supplied by sustainable organic fuels. Low-carbon-number alcohols and,

where necessary, synthetic hydrocarbons, can be supplied from the biosphere up to the

biomass limit from biofuels, and beyond the biomass limit from the atmosphere and

oceans using captured CO2 and hydrogen electrolysed from water.
