Similarly to solar energy, wind energy is a regenerative form of
energy. It differs in that it has been used by man for centuries,
for example, in windmills, in which it is converted to mechanical
energy. In recent times, wind power plants have been brought to use
for the generation of electric energy. As with solar energy,
however, such plants cannot produce it for use when it is required,
as generation is wind-dependent. This makes energy storage
necessary. A present possibility for this is to convert the energy
to hydrogen. The total process is then as follows. The wind energy
generates a voltage by means of a generator and the voltage then
used to decompose water to hydrogen and oxygen. These can be
relatively easily stored and can be converted back to electric
energy and water by a fuel cell when energy is required.
In this experiment, the hydrogen system is to be driven by wind
energy.
An examination is to be made on to which extent the hydrogen
generated can be used to supply the fuel cell and drive the
connected motor.
