First liquid hydrogen carrier ship launched in Japan paves the way for a clean hydrogen export industry for Australia

With Australia having lots of potential for solar and wind electricity it is looking to a future of making renewable/clean hydrogen (H₂) from the electrolysis of water (H₂O). Hydrogen is a powerful energy source that can be stored, transported and used for electric cars, heavy transport, industry and even steelmaking. It will also be possible to repurpose natural gas power stations to burn clean hydrogen to make electricity (Dr Alan Finkel, Australian Chief Scientist, National Press Club Address).

The technology is now here for the safe storage of liquid hydrogen and the ability to ship it around the globe. So much so, the first liquid hydrogen carrier ship has been launched in Japan and will be used to take hydrogen from Victoria, Australia, to Japan starting in 2021. The hydrogen will be cooled to –253^oC, to reduce volume, and stored it in a vacuum-insulated, double-shelled tank. This ship is powered by diesel, but it is hoped that ships in the future will be driven by fuel cells powered by clean hydrogen. 

Although the first shipments will be carrying hydrogen made by heating water by burning coal (and capturing and storing the carbon dioxide), this ship will pave the way for more ships to carry renewable hydrogen from Australia to Japan, South Korea and possibly Europe. Other Australian businesses are looking to make hydrogen from renewable electricity, particularly solar. It is predicted that there will be near a $2 trillion market for clean hydrogen by 2050 (Dr Alan Finkel, Australian Chief Scientist, National Press Club Address).

Post script: Export of blue hydrogen project starts in Victoria. It makes hydrogen from coal and plans to capture the CO2 in empty natural gas caverns in Bass Strait. The project will not be commercialised if the carbon capture is not feasible. Hydrogen project fuels Latrobe Valley job hopes as coal plants close. The Sydney Morning Herald, March 12, 2021.
