The report explores different alternative fuels to replace petrol, diesel, and liquid petroleum gas in transportation. It compares ethanol, methanol, hydrogen, biodiesel, and dimethyl ether. Dimethyl ether is the best short-term alternative to diesel due to its environmental impact and cost. Liquid petroleum gas is the best short-term alternative to petrol. In the long term, no single fuel can meet demand sustainably, but dimethyl ether could be the best option with improved biomass production.
