Green hydrogen may well be the power source of the future. If its use is still contested by detractors in some areas of transport, it would be objectively difficult to refute its potential for industry at large. The real question then is, and will be for some time, where do we get it from in quantities sufficient for current and future demands?

Put differently: 1) is there enough of it now? 2) can and will there be enough of it tomorrow? 3) how do we get it from current and future production sites to the places where it is required?
