The rapid decline of fossil fuels and their constantly increasing prices have led to growing interest and search in the area of alternative options for these fuels.
Methanol and ethanol are good substitutes for petroleum fuels, and can be made readily from non-petroleum sources and by fermentation of carbohydrates and starch found in biomass and other natural products like sugarcane, potatoes and corn.
Biodiesel is a form of diesel fuel manufactured from natural oils, animal fats or recycled restaurant greases.
Ammonia and hydrogen are also being researched as fuels for S.I. engines offering a carbon free fuel solution.
Compressed natural gas (CNG) is a clean burning alternative fuel. It can be used in compressed or liquefied form to fuel vehicles.
Many vegetable oils can be used in diesel engines like peanut oil, linseed oil, and sunflower oil.
Cold pressed rapeseed oil (KRO) has been investigated for use as fuel in light duty vehicles.
Biogas is also being researched and increasingly adopted as a sustainable fuel for I.C. engines.
Algae-based biofuels and liquid nitrogen are also seen as promising options for future research.
