Alternative Fuels to Oil Essay -- energy oil power ethanol biodiesel h

Recently option send aways have been gaining popularity, especially here in the unify States. The advantages of some of these fuels be being recognized with the rising cost of crude inunct. Other countries round the world have been utilize utility(a) fuels for years, such as in Brazil where they have good feedstock for some fuels such as ethanol. Biofuels ar also becoming cost effective with higher crude oil prices and earth-closet be completely re bare-assedable. The best thing approximately many of these election fuels is they can be readily used in old-hat internal combustion engines with little or no modification.The list of alternative fuels can go on forever, only if some of the most reciprocal and readily adaptable fuels are ethanol, biodiesel and hydrogen. Of course these fuels all have their drawbacks, but so do petroleum based fuels, we have just engineered nearly some of the disadvantages. The same thing can be done with these alternative fuels engineer around the disadvantages. Most of these fuels do not release new carbon into the atmosphere which is a good thing, we dont need any supererogatory carbon in the carbon cycle.The following pages explain what some of these more common fuels are as well as some advantages and disadvantages of each. neutral spirits is a common fuel that can be produced from many several(predicate) crops, for example corn is a common feedstock for ethanol production here in the United States. Other countries around the world produce thumping amounts of ethanol to power many of their vehicles. For example Brazil has a consummate climate to grow sugarcane, which is a great feedstock for ethanol. As a impression many of their cars run on pure ethanol. Here in the United States you have probably heard of Flexible Fuel Vehicles (FFVs) which are ... ...ever with the contemporary technologies the most economical way to produce hydrogen is by using fossil fuels. To produce hydrogen by electrolysis a cur rent is utilise to water to seperate the hydrogen molecules from the oxygen. This process is actually pretty energy efficient, from about 50-75% efficient with theoretical efficiencies from 80-94% (Electrolysis-Wikipedia).What is the best way to transport hydrogen? Because it is a gas at standard temperature and pressure, large high pressure tanks are required to transport it. This can present some safety and widescale diffusion issues. Another way to utilize hydrogen gas on vehicles is with fuel cells. These cells will convert hydrogen gas into electrical energy that can be used to drive the car. With our current fuel cell engineering science they have a relatively short lifetime and are high-ticket(prenominal) (Fuel Cell-Wikipedia).
