"Japan ... will also import hydrogen, with Australia the seeming front-runner, using its plentiful coal supplies to make hydrogen and capturing the resulting carbon dioxide emissions."

This sounds highly unlikely in the foreseeable future given the Australian governments record and attitude to green issues -

from Wikipedia
"There are no currently-operating large-scale CCS projects in Australia, although the Gorgon gas project will qualify when it is fully operational. Despite multiple CCS demonstration projects at Australian coal-fired power stations, none of Australia's coal plants are currently capturing CO2 or have a time frame for doing so. Australian Treasury modelling finds that CCS is not expected to be commercially viable until the 2030s.[1] The Intergovernmental Panel on Climate Change (IPCC) estimates that the economic potential of CCS could be between 10% and 55% of the total carbon mitigation effort until 2100.[2]

In the 2017 budget, the Turnbull Government announced the cessation of the Low Emissions Technology Demonstration Fund in the 2017 financial year and the cessation of business case funding for the Carbon Capture and Storage Flagships program in financial year 2019.[3] This is on top of the 2015 budget, where the Abbott Government cut $460m from CCS research projects leaving $191.7m to continue existing projects for the next seven years. The program had already been cut by the previous Labor government and much of the funding remained unallocated.[4] "

So...let's make hydrogen by burning coal .... greenwash........
