From my limited capacity to fully understand it all, HYSR's tech is not simple, but it appears simple to implement, and it is scalable for more industrial apps. Compression and storage of the resulting H2 is another tech already here, but to try and answer your question, seems to me that this tech is the best suited for small scale applications. The world has first to decide to switch horses, or at least begin slipping off this hydrocarbon hay ride. H2 revolution would solve so many problems at the same time, it's hard to know where to begin. The first being the big existential challenge of our time, but not to be discounted is the enormous benefits to economies as they begin and then accelerate the conversion to a H2 economy and infrastructure. With much localized production, the need for the kind of infrastructure associated with extraction, transport, refinement and storage of fossil fuels simply isn't there, but fresh technologies, all much cleaner the old, will be required and fresh infrastructure to go with them. We encounter gasoline when we fill up, that's all most of us know of the filthy journey those 50 litres made to get there.
