When Natural Gas /CNG/Methane was introduced as a fuel, Science faced similar issues pertaining to storage and transportation.
Then science developed Cryogenic tanks / containers which can transport the Gas in form of LNG through ships from one country to the other. By the way, during 2021-22, India imported 32 Billion Cubic meters of Natural Gas from other countries.
In a similar way , Hydrogen can also be liquified and transported through cryogenic tanks. Apart from this Hydrogen can also be transported as Ammonia as a hydrogen carrier.
And Hydrogen is already being shipped through ships from Australia to Japan.
And the point that if the ship runs in fossil fuel , it is no longer green… is correct …but then if A car or a Bus can run on hydrogen , trains can run on hydrogen , why not ships ???
Yes , ships can too run on hydrogen and it is already running .
Cheers !
