Ethanol fuel specifications worldwide traditionally dictate use of anhydrous ethanol (less than 1% water) for gasoline blending. This results in additional costs, energy usage and environmental impacts associated with the extra processing step required to dehydrate the hydrous ethanol produced via distillation (3.5-4.9 vol.% water) to meet the ...
The fraction of water that an ethanol-gasoline fuel can contain without phase separation increases with the percentage of ethanol. [29] For example, E30 can have up to about 2% water. If there is more than about 71% ethanol, the remainder can be any proportion of water or gasoline and phase separation does not occur.
Methanol (CH 3 OH) is less expensive to sustainably produce than ethanol fuel, although it is more toxic than ethanol and has a lower energy density than gasoline. Methanol is safer for the environment than gasoline, is an anti-freeze agent, prevents dirt and grime buildup within the engine, has a higher ignition temperature and can withstand ...

Picture showing E0 100% gasoline at $1/gallon more than E10 Regular Unleaded. At this same Saugatuck, MI Shell station, E85 was an additional $1/gallon below regular ($2/gallon below ethanol-free Rec-90). As debate has ensued over ethanol blending in gasolines, ethanol-free has popped up in a number of states marketed as Rec-90 Recreational ...
Little to no ethanol will qualify for U.S. sustainable aviation fuel (SAF) subsidies under a new pilot program by President Joe Biden's administration, which toughened climate requirements at the ...
It can be made from renewable electricity, and having half the density of petrol or diesel can be readily carried in sufficient quantities in vehicles. On complete combustion it has no emissions other than nitrogen and water vapour. The combustion chemical formula is 4 NH 3 + 3 O 2 → 2 N 2 + 6 H 2 O, 75% water is the result.
Butanol better tolerates water contamination and is less corrosive than ethanol and more suitable for distribution through existing pipelines for gasoline. [15] In blends with diesel or gasoline, butanol is less likely to separate from this fuel than ethanol if the fuel is contaminated with water. [15]
