Hydrogen is often slated as a solution that could deliver zero-emission benefits without the substantial changes to operations and widespread infrastructure of electrified alternatives. But just as the energy carrier’s properties make it suitable for some applications, they make it notoriously difficult to store and handle.
The majority of the existing (grey) hydrogen is consumed near to where it is used. However, this looks to change as regions look to harness its zero-emissions benefits when produced from renewable sources. The Hydrogen Council’s Global Hydrogen Flows report said that 400 million tonnes – of the 660 million needed for Net Zero in 2050 – could be transported over long distances1.
But with a low volumetric density, unless compressed or liquefied, hydrogen uses a huge amount of space and can leak easily.
