2/9

Alternative Fuels

In recent years, the demand for vehicles with lower CO2 emission has

increased greatly.

New alternative fuels are being used to replace traditional petroleum.

The increased use of low-emission vehicles has become a common

sustainable issue.

There are many different types of alternative fuels currently available.

Some examples include alcohol/ethanol, vegetable oil, LPG and solar.

The most common type of alternative fuel is electricity.

Hybrid-electric vehicles use a separate electric motor which powers the

vehicle independently of the main internal combustion engine.


3/9

Hydrogen as a Fuel?

Hydrogen does not occur freely in nature, it can be produced by reforming

fossil fuels or by splitting up water components by means of electrolysis

Hydrogen could be used in two different ways to power a vehicle.

Either directly in an internal combustion engine, replacing petrol, or in

Fuel Cells used to create electricity to power an electric motor.

Currently the only hydrogen filling station in the UK is in Hornchurch, Essex

(Auto Trader, 2006, para. 9).


4/9

Advantages

Produces virtually near zero emission. Potential supply is unlimited.

Most abundant element on Earth.

Only by-product is water.

Expensive to turn into an energy carrier.

Has to be stored in extreme conditions.

If used in internal combustion engine rather than in fuel cells, efficiency isreduced.

Graph shows CO2 emission from different alternative fuel vehicles compared to

conventional petrol cars. The lower the better.

The H-7 does not compare too well relative to other fuel types. According to the

graph, using hydrogen in fuel cells is much more carbon friendly.

Again the H-7 has a relatively low reduction in carbon emission overall.


8/9

Conclusion

Hydrogen in theory sound like the best alternative fuel solution that will

lower carbon emission.

When used in an internal combustion engine is not efficient enough to

have a sustainable effect.

It is much more efficient and sustainable to use hydrogen in fuel cells. Alternative solutions to hydrogen provide less carbon emissions.

Internal combustion engines are not ready to cope with effectively

burning hydrogen.
