Top 9 Alternative Fuels for Gasoline Cars
- 1. Top 9 Alternative Fuels GetElectricVehicle
- 2. What is the commonly used fuel in vehicles? • Petroleum is the most common fuels used in vehicles • Matured technologies for fuel extraction • Well developed combustion engines GetElectricVehicle.Com
- 3. Why do we need alternative fuels? • Depletion of fossil fuels • Environmental pollution from Carbon dioxide, Nitrogen dioxide, and carbon monoxide • 1 liter of Petrol emits 1kg of CO2 when it burnt • The green house gas emission increases the temperature • Global warming GetElectricVehicle.Com
- 4. Disadvantages of Fossil Fuels • They are non renewable source of energy • It takes very long to form the fossil fuel • They cause air pollution • They cause global warming • Some countries get economical benefits from the fossil fuel reserve GetElectricVehicle.Com
- 5. Alternative fuels for cars • They are tested and proven technologies • Some alternative fuel are commercially used GetElectricVehicle.Com
- 6. List of the Top 9 Alternative Fuels GetElectricVehicle.Com
- 7. #1 Biodiesel • Renewable source of energy produced from vegetable oil, animal fat, etc. • Produced by chemically reacting lipids with an alcohol producing fatty acid ester • Diesel engines cans use Biodiesel alone or blended with petroleum fuels GetElectricVehicle.Com
- 8. #2 Methanol • Less expensive to produce for internal combustion engine vehicles • Many counties use methanol as a fuel alternative in race cars • Similar to biodiesel, methanol can also be used alone and blended with petroleum fuels GetElectricVehicle.Com
- 9. #3 Ethanol • Ethanol (ethyl alcohol) is made up from sugarcane or corn • Relatively high energy density • Gasoline gallon equivalency of ethanol is approximately 1.5 • Ethanol blended fuels are widely used in Brazil, the United States, and Europe • Produced converting carbon-based agricultural feedstock such as sugar cane, bagasse, grain, barley, potatoes GetElectricVehicle.Com
- 10. #4 Compressed Air • The energy density of compressed air is low • A pneumatic motor that works on expanding compressed air is used to convert the energy to mechanical energy • Compressed air results no air pollution • Less efficient in energy conversion • Regenerative braking can be used in compressed air vehicle GetElectricVehicle.Com
- 11. #5 Hydrogen • Hydrogen is a fuel that can be used in two ways in a vehicle • Hydrogen can be either burned in an IC engine to power the car to move or it can be used with oxygen in a fuel cell to run an electric vehicle • Honda Clarity, Toyota Mirai are a few examples of hydrogen-powered vehicles • Hydrogen fuel is expensive and highly inflammable • They are not popular in the automotive industry GetElectricVehicle.Com
- 12. #6 Electricity • Electricity is considered as an alternative fuel under energy polity act of 1992 • The Electric vehicle has zero/low tailpipe emission • An electric vehicle converts electric energy stored in the battery to mechanical energy using electric motors • EVs are not limited to road transportation • Electric aircraft Solar Impulse 2 revolved around the earth only using electric energy GetElectricVehicle.Com
- 13. #7 Natural Gas • Compressed Natural Gas (CNG) and Liquefied Natural Gas (LPG) • Natural gas is a mixture of gases that are rich in hydrocarbon • Gasoline-powered vehicles may be converted to a natural gas vehicle or they can be used as bi-fuel (petrol and CNG) vehicle • Low emission of environmental polluting gases • CNG vehicles are popular in cities such as Delhi GetElectricVehicle.Com
- 14. #8 Propane • Liquefied Petroleum Gas (LPG) is a mixture of Propane and Butane • Some variants of natural gas are primarily propane • They are called propane fuel • Liquefied petroleum gas which is commonly called Autogas • It is the third most popular automotive fuel in the world • It is one of the alternative fuels for cars • Carbon dioxide emission of autogas is around 15% less than that of petrol GetElectricVehicle.Com
- 15. #9 Fuel Cell • A fuel cell is an electrochemical cell • Converts chemical energy from a fuel into electricity • A continuous supply of fuel is necessary for a fuel cell to generate electricity • The generated electricity is used for vehicle propulsion • Why fuel cells are important? • Fuel cells emit water as bi-product of energy conversion GetElectricVehicle.Com
- 16. Key Points • Alternative fuel vehicles are required to reduce environmental pollution and global warming • To tackle the reduction of non-renewable fossil fuels, fuel alternatives are necessary • Electricity is one of the best alternative fuels • Vehicle manufacturers go for the electric vehicles GetElectricVehicle.Com
- 17. Key Points • We would say, electric vehicles are super clean, at least at vehicle side • We expect a bright future for electric cars rather than other alternative fuel cars What would you think? GetElectricVehicle.Com
Editor's Notes
- That is 1.5 unit volume of ethanol can replace 1 unit volume of gasoline in terms of energy
- The energy density of compressed air is low and its pressure falls as air is taken from the tank A pneumatic motor which works on expanding compressed air is used to convert the energy to mechanical energy – either linear motion or rotation Even though compressed air results no air pollution, its inefficiency in conversion and low energy density make it less competitive Regenerative braking can be used in compressed air vehicle to recuperate the energy that would have dissipated as heat during braking
- A fuel cell is an electrochemical cell that converts chemical energy from a fuel into electricity through an electrochemical reaction of hydrogen fuel with oxygen or another oxidizing agent
- (keep aside the process of electricity generation)
