This is part two of our three-hour interview with Dr. Simon Evans of Carbon Brief about their extensive survey of the developing hydrogen economy. In part one of this interview, which we featured in Episode #142, we discussed the current expectations for the hydrogen economy, the various projections for hydrogen production and use; the different methods of producing hydrogen and the names we use to refer to them; the state of the global hydrogen business today; the potential roles that hydrogen might play in tackling climate change; and the questions around what hydrogen costs today and may cost in the future. In this second part, we’ll talk about the various potential applications of hydrogen sector by sector and by use, and attempt to start sorting out where hydrogen might really have an edge, and where it might be just a potential application that might never become a commercial reality.
