Hydrogen, like electricity, is an energy vector and it can be extracted from water or organic compounds using external energy sources. There are now over 220 hydrogen refuelling sites worldwide and most of the major automobile manufacturers are working on hydrogen fuelled vehicles. Hydrogen is at present mainly produced from fossil fuels, particularly from natural gas by steam methane reforming but must ultimately be produced from renewable resources to minimise CO2 emissions.
