The point is both Natural Gas and Hydrogen - are Gases at atmosphere temp and pressure and thanks to the cryogenic technology by which it is possible to store both gases at liquid form @ - 160 to -260 degree C and thus both can be transported in Cryogenic tanks…
Ammonia as a Hydrogen carrier is only an alternate option which in fact is easier as storage and handling of Ammonia is already in place since Ages…Ammonia itself can be used directly as a fuel-technology for which is already available- and it serves the same purpose as of Hydrogen as fuel emitting Zero carbon. But to get pure hydrogen out of ammonia for electricity generation , it needs to dehydrogenated for which multiple options of technogy being explored keeping cost in mind.
India is in a better position to produce hydrogen due to the obvious reasons as discussed in the thread and whether we would like to accelerate our production capacity and export a part of it or not - it entirely would depend upon Govt decision- but the market for Green hydrogen will always be there from many other countries like Europe and Japan who are keen to switch to Green hydrogen and they donot have the advantages like India for producing Green hydrogen in a massive scale.
Let us look at how EV is getting introduced in spite of being more Expensive than diesel petrol engine vehicles…CNG vehicles were costlier than diesel/ petrol vehicles …CNG price has also gone up to Rs76 a kg as against Rs 35 a kg a decade back… but still we are now adopting the CNG technogy extensively…and today every Auto manufacturer is making CNG vehicles in large numbers- whether it is a car or a Bus or a three wheeler.
…when the entire world is working unanimously and wanting to switch to Green hydrogen…everything could be possible…cost…transport …technology…
…though all this are not going to happen tomorrow or day after tomorrow… it would be a gradual process…all alternate sources of energy may coexist for a decade …until economy of scales develops with advancement of technology.
But the journey towards carbon free world has already started !
