Hydrogen has been touted as one of the key components of a successful energy transition and, in advance of the summit, governments around the globe have pledged millions towards investment in the production of both its blue and green variants.
It has the potential to revolutionise our energy systems, with the capability of decarbonising everything from local bus services to heavy manufacturing. As a result, hydrogen demand is expected to rise to a record-breaking 140 million tonnes per year by 2030 – a 35% increase on current output – and in excess of 690 million tonnes by 2050.
