Alternative fuels

Fuel prices are very high at the moment. Took in 2000, a liter of gasoline ?? 1.05, now you pay for the same liter of gasoline about ?? 1.35. As a result, the cost of a car ride of course very much. So it is really expensive to go by car ride and this also leads to a search for alternative fuels. Our oil fields are running out. Oil companies expect around 2008-2009 to almost all stocks worldwide map. And then the countdown ..... 20 ... 50 .... 150 years? Nobody knows exactly, but it will be once ........ that everyone agrees on! Alternative fuels are fuels such as biodiesel, bioethanol, pure vegetable oil, hydrogen, natural gas and electricity.

Why will people alternative fuels?

The first we have already mentioned: the outrageous, but there are more reasons. Our oil reserves are limited and we consume so much oil that the earth about 100 years altogether. In addition, you obviously have the pollution. As more and more cars come ?? s on earth, the air is even more polluted. High time for action so!
We distinguish between two groups of alternative fuels:
  • biofuels
  • hydrogen and electricity

What are biofuels?

Biofuels are fuels produced from grass, plants, trees or waste materials. This means that the supply is virtually inexhaustible because you just grow more plants to extract fuel if necessary. This is in contrast to the oil fields, which touch at one time. Biofuels can fossil fuels such as petrol and diesel substitute.
First I want to tell you about bioethanol. Bioethanol is alcohol which is made from suikkerriet, corn, wheat or sugar beet. Also cereals like barley and byproducts of these are suitable. The main advantage of bioethanol is of course that it is inexhaustible; you just turn plant trees shrubs as bio-ethanol, and that gives you Mathews fuel from there. Sweden already ?? many cars and buses on bioethanol. A disadvantage is at this point that the cost of this fuel are higher than gasoline and diesel.
Then we have biodiesel. This is similar in characteristics very similar to ordinary diesel. Biodiesel is made from rapeseed oil and sunflower oil. Today, biodiesel is often made from algae. Algae have the advantage that they consume a lot of CO2 and they grow fast. This fuel is on the rise and especially abroad is already driven by this fuel. It is a good alternative to regular diesel because fewer pollutants are emitted as CO2. It is also better for the engine because biodiesel is oilier than ordinary diesel, this engine is also lubricated.
Vegetable oil
Furthermore we have pure vegetable oil, also referred to as PPO. Pure vegetable oil as biodiesel made from sunflower seeds, palm nuts, canola and soy. Here are the nuts squeezed so that the oil comes out. The difference with biodiesel is that PPO needs to be processed as far. Unlike the pure rapeseed oil biodiesel is not a diesel. In order to use this product in an internal combustion engine, the engine must be adjusted. This entails significant costs. We speak after the cultivation no longer a diesel engine but with a vegetable oil engine. The advantage of this is that the price per liter ?? 0.20 is lower than with conventional diesel. As a further disadvantage you can call the greenhouse that gives a PPO. In the Netherlands, you only have a limited number of stations where you can refuel PPO. If you still find too expensive, you can buy a bottle of cooking oil in the supermarket, which empty into the tank. Unfortunately, this is not legal because there is in fact no tax payable on.
As we face the future with biofuels. In many countries in the world and especially Europe as they drive partly on biofuels, and the Netherlands is a maverick; We can hardly fill up biofuels. For pleasure boats can biodiesel into Sneek because they sell do it. Shell, however, does or biofuel with petrol, but this is only 2%. Here, e and ordinary diesel vehicles not affected and as a driver you do not notice here.
What does it mean to run on biofuels?
Is it cheaper to run on biofuels? In order to make your car to run on biofuel have to let you convert him; it costs 800 euros. But there are car manufacturers such as Ford, Volvo and Saab that fit the engines for all types of fuel: a sensor in the engine detects the fuel is inside and automatically adapts. It is important that we start driving on biofuels because it is much better for the environment and the fuel is easy to produce. In addition, it is also good for the engine and the engine performance will be better. The expensive end of the run on biofuel, the one-time conversion of the engine, but the price per liter is lower than for fossil fuels.

Hydrogen and electricity

Then, the second group of alternative fuels, hydrogen and electricity. It is currently busy developing the hydrogen engine. There are two types of hydrogen engines: a hydrogen internal combustion engine and a fuel cell. A fuel cell means that hydrogen is converted into electricity.
First hydrogen must be made, this is done in special circumstances and there is much need electricity to make hydrogen. In addition, the hydrogen under low pressure and extreme cold is to be stored. If the auto fill up hydrogen, it is stored in a special tank. When you start driving, the hydrogen engine burns hydrogen and goes forward.
Advantages of this fuel is that there is only water vapor comes out of the exhaust, it is 100% clean. The hydrogen car emits no foul substances, except water then. The performance of a fuel car are also higher, this is because hydrogen much harder blows than for example gasoline. There are hydrogen car ?? s in 3.5 seconds down on 100 km / h. But you can do more with hydrogen: Amsterdam is a boat made using hydrogen to sail.
Furthermore, you have the fuel cell. This is a hydrogen engine that makes use of electricity. By which power the electric motor to rotate and put the vehicle in motion. So here comes to pass with no combustion. However, there are drawbacks to hydrogen: it is difficult to transport, and it is very dangerous and flammable.
To achieve it, however, that car ?? s driving on hydrogen?
Yes, but look at our neighbor Germany. There are already driving BMW 7-series around on hydrogen. However, the fuel is not yet readily available. Only near Munich and Berlin, there are few hydrogen filling stations. This is obviously a disadvantage to the purchaser of this BMW. You can not get too far away from Berlin or Munich, or else you stand on the side of the road. But once there are enough hydrogen fuel stations, this is very interesting. Unfortunately, the price per liter of hydrogen very high and therefore not have to pay for the average motorist.
Furthermore we have the normal electric motor. You load the battery at home and you can drive. This is of course very good for the environment; emissions is also 0. A drawback of electric cars is that the battery you home for a while on the charger should explain, this of course takes a lot of power.
It is difficult to choose which is better: on hydrogen or just a battery. Hydrogen can be as fuel, a battery must explain your long time in a charger. There is also something important: to make hydrogen, you need a lot of electricity. And a power plant to use nuclear energy to make that electricity, which is also not clean. The best course would be that you can charge the battery of your car through solar panels; it is environmentally friendly.
It would also be very nice if we car ?? s solar panels could let it ride. The disadvantage is that this is detrimental to the appearance of the car and you need a huge stretch of solar panels to generate additional electricity.
In any case, it is clear that we must move on to other fuels. There are a lot of developments in the field of alternative fuels but it will be some time before all the service stations which have fuel. Also, many automakers reluctant to really bring it through development. It's obviously not nothing that many new gas stations to come and that of course the consumer dares to buy a car on a fuel other than petrol or diesel. The government wants is 5.75% share of biofuels in 2010. But one thing is clear: this is much better for the environment and moreover we draw not from our oil resources and limiting environmental pollution. And if we all switch to alternative fuels, they are also much cheaper.

Is it possible, as with the hybrid cars to create a hybrid of electricity and hydrogen, if the hydrogen still running out accidentally that you can step and continue as electricity over?
