Hydrogen (H ₂) has been deployed as an industrial gas for over one hundred years and large volumes are used across the widest range of applications every day. Hydrogen is also set to play a defining role in the much-publicised third, 'green' industrial revolution. It is the most commonly occurring element in nature and – unlike fossil fuels such as crude oil or natural gas – will never run out. Like electricity, hydrogen is an energy carrier – not a source of energy. It must therefore be produced. Yet hydrogen offers several key benefits that increase its potential to replace fossil fuels. Stored hydrogen, for example, can be used directly as a fuel or to generate electricity.

Hydrogen will open up regenerative, sustainable mobility choices in our everyday lives. Hydrogen-powered vehicles have a long-distance range and can be rapidly fuelled. Decades of research, development and testing have shown that hydrogen technology is a workable, economically viable alternative suited to mass deployment.
