While hydrogen is mainly used in fertilisers and explosives at present, the push to lower emissions may see hydrogen fuel cells become a more common energy producing resource.
The chemical element hydrogen is found in water and organic compounds like methane and can be stored as a liquid or a gas and used as a powerful source of energy.
Liquid hydrogen rocket fuel launches astronauts into space and hydrogen fuel cells power cars, trucks, trams and shifts.
However, costs will have to be brought down to and production increased for hydrogen power to become a more viable option for a broader range of people.
