Although hydrogen is the most abundant molecule in the universe, it only exists combined with other elements, for example in water (H2O). Not only does it have to be extracted using energy-intensive processes, 98 per cent of hydrogen produced today is extracted from fossil fuels. All this results in a large carbon footprint.
