Hydrogen has been proven to be a reliable source of fuel, which can be used to power cars with top speeds of over 100mph
Hydrogen cars in crash tests have been proven to be as safe as conventionally fuelled cars
How suitable is hydrogen as a fuel
So far hydrogen cars have reached a maximum range of 217 miles per tank of fuel
Hydrogen fuel cells are around a third the size of a average conventional engine
Hydrogen filling stations currently only exist in an extremely limited number of places currently, however there are plans for there to be 1 in every European capital by 2005
Hydrogen cars are expected to cost under £20 000 when they first go on sale to the general public
Availability and cost
Maintenance cost of hydrogen fuelled cars are very low as the fuel cell itself contains no moving parts
Hydrogen cars could cost as little as 1p per mile to run if water is used as the hydrogen source
Hydrogen is burnt in fuel cells producing water and heat. It is practically useful because it produces no other waste products so does no damage to the environment.
Hydrogen is also the most plentiful substance in the universe. A major source on earth is water which is nearly inexhaustible unlike many traditional fuels.
Practicality and Range
Hydrogen cells have an efficiency of around 60% in comparison to the 20% of combustion engines.
The most common hydrogen cells (the PEM) can be used in cold weather conditions as well as in extremes heats.
Hydrogen can simply be obtained through electrolysis of water.
New methods of storing hydrogen allow up to 7 gallons of hydrogen to be stored in a single gram of material.
Hydrogen fuel cells are compact and light weight. Hydrogen cars can be filled in as little as 5 minutes.
Refrigerated and pressurized tanks could allow hydrogen powered cars to go 5000 miles on a single tank. (weighing less than 200lb)
Although it would be difficult to adapt existing cars to used hydrogen systems many major car companies are investing heavily in the development of hydrogen cars.
New methods of storing the hydrogen and more advanced fuel cells are reducing the need for the fuel to be held at such low temperatures.
Hydrogen Has to be stored at low temperature and under high pressure for use in cars.
Storage and Distribution
Many Hydrogen filling stations are already in existence although these are mostly in remote areas it is hoped that this technology could easily be adapted for larger scale use.
It is hoped that within Twenty years there will be hydrogen filling stations in all major cities and car companies will be producing affordable and efficient hydrogen powered cars.
Environmentally friendly hydrogen can only be achieved if the production of the hydrogen does not involve the emission of greenhouse gases.
