Unlike batteries, fuel cells should not be replaced. Fuel cells convert chemical energy into electrical and then, namely, not to replace the fuel element, but also a source of chemical energy, in this case, hydrogen can be stored on board. For more information about the fuel cell, click here

Properties
The liquid, non-toxic and biodegradable

Manufacturing
Most of the electricity produced at power plants using fossil fuels, despite the small number of results from wind and solar energy.

Emissions of CO2
Zero
Most of the electricity produced at power plants using fossil fuels, despite the small number of results from wind and solar energy.

The fuel mixtures
No
Biodiesel can be used with conventional diesel in any proportion, either at the factory or in a tank. Nevertheless, it is usually mixed about 2% (B2) 20% (B20). Mixtures B5 do more to the user requirements, changes and demands special treatment.

Infrastructure
In its place.
With BEVs requires only electrical outlet to recharge a car battery, the infrastructure already exists in the network utilities. A small number of U.S. states now have one or two recharge electric stations, but this figure is expected to increase.

Advantages

• Power has the highest efficiency of any distribution of fuel, including gasoline. Distribution is to determine how much energy is lost effectiveness of the entire chain, from production to transportation to end-users. The distribution of fuel efficiency is about 80%, while the power of 95%.
• new, even an overview of the infrastructure is not necessary

Disadvantages
• Currently BEVs not very good, and if they do not, remain unattractive to consumers

In the future…
… Over the use of electricity is very bright. Electricity consumption in most BEVS created by power plants with fossil fuel energy. I hope, is the use of renewable sources (excluding oil) of fuel to create that energy prices.

In addition, recent advances in the wheels, storage and nanotechnology indicate that the car batteries, a bit distant future may be much more effective than the current batteries. Please read our new technology to get more information about this incredible battery.

Renewable fuels
Biodiesel is one of the most studied alternative fuels in the world and has a number of promises for cars with diesel engine compression igniton.

Properties
The liquid, non-toxic and biodegradable

Manufacturing
Biodiesel begins with fresh vegetable oil (such as soybean, rapeseed, palm or coconut oil), animal fats and oils fish or recycled cooking oil. Using the producers of chemical reaction called “transesterification” chemically react acids in vegetable oils with methanol () and adding catalytic converter. Fat molecules in the oil in a fatty acid methyl esters (FAM) or alkyl esters.

Emissions of CO₂
Net of zero emissions
Only CO2 released by burning biodiesel is the beginning of CO2 absorption of biological material (plants, etc.) during their development. However, fossil fuels are currently used in production.

The fuel mixtures
Yes.
Biodiesel can be used with conventional diesel in any proportion, either at the factory or in a tank. Nevertheless, it is usually mixed about 2% (B2) 20% (B20). Mixtures B5 do more to the user requirements, changes and demands special treatment.

Infrastructure
In its place.
Order. You can take advantage of the current road system of conventional diesel fuel, but also their ability destructive problematic for the pipeline system.

Compared with diesel
She higher density, lower calorific value, lower sulphur content, falling oxidation stability, and is about 92% as efficient as conventional diesel fuel (that is 8% less energy per unit volume).

Advantages

• Biodiesel is already largely compatible with existing conventional diesel engines, and some of its infrastructure.
• The burning does not contribute more CO2 in the atmosphere.

Disadvantages

• Recording B100 (100% biodiesel), may be exempt from nitrogen oxides.
• Some corrosion of metals can be in contact with biodiesel, the creation of deposits and fuel system. It can also be used in respect of certain types of plastic and paint industries.
• Currently, the total cost associated with biodiesel are inaccessible.

In the future…
… This is brilliant for biodiesel. Throughout the world, this rapidly growing industry, and is considered one of the most promising new fuel during this period. In the U.S. alone, there are currently more than 140 biodiesel plants in operation and another 96 in accordance with construction
