Hydrogen is a very clean fuel that is increasingly being used as vehicle fuel and to generate electricity. The problem is how to produce it efficiently without generating significant carbon emissions and at a competitive cost. A team of researchers at Imperial College is currently looking at the problem and think they know how to do it.
Fuel Cell vehicles
Vehicles can be fitted with a hydrogen fuel cell which converts the chemical energy of hydrogen to mechanical energy. Fuel cells do this through a chemical reaction between hydrogen and oxygen which in turn runs an electric motor.
