Two approaches to developing hydrogen economies that extend to maritime transport were graphically highlighted in plans recently laid out by the UK and Germany.

The UK’s Hydrogen Plan for £4bn ($5.5bn) of investment in the fuel by 2030, most of which is envisaged to come from the private sector, pledged no new money to shipping.

The strategy repeated a past pledge to invest up to £20m in a Clean Maritime Demonstration Programme to develop green shipping technology and noted that the HySeas project to develop a hydrogen-powered ferry for the Orkney islands is in its final development stages.
