Ann: WAH2 Project - Low Emissions Ammonia Investor Briefing, page-6

i think the cold, hard facts of hydrogen smacked Twiggy in the face. Splitting water isn't as easy or cheap as he thought. And tgen splitting H from gas is a capital intensive operation. Storing the co2 underground is a very expensive and technically challenging task. All these processes waste massive amounts of energy, which sort of sucks when it is meant to save the planet. Then, to be able to ship.it you need to combine it with nitrogen, ship it, and then separate the nitrogen at the other end to get hydrogen. And doing all those processes economically against Japan just buying gas is a monumental task.
