Abstract

In this project, we address the issues of using petroleum products to fuel vehicles and talk about other alternative fuel options. The main problem with using petroleum is the CO2 emission, which cause global warming, an effect that can have devastating impact on every life form on this planet. Another issue with dependence on petroleum is the economic and political instability it causes. Many alternatives are proposed, some are being carried out; but they have strengths and weaknesses. Hydrogen fuel cells, while can power car without releasing greenhouse gases, are hard to produced efficiently without using fossil fuels. Electricity is very efficient in powering vehicles but it faces major difficulties in making batteries at substantial quality. Ethanol is an energy carrier for the Sun, theoretically it can be carbon neutral but the production of ethanol is not efficient, making it a less viable choice. Natural gas is an abundant energy source but nonetheless limited and not carbon neutral. Algal biofuel, on the other hand can be carbon neutral and also very efficient to produce. Hence, we conclude that algal biofuel is the most promising fuel for vehicles in the near future. However, further research is necessary before algae can be used to replace petroleum. To promote algae researches, we want to ask the coal industry to use algae to reduce their CO2 emission. If this is carried out, it will direct more attention toward algae and also helps reduce CO2 emission. (VN)
