Everyone seems to be excited about hydrogen lately, pointing out its many potential applications and claiming that a global hydrogen economy is a key strategy in energy transition. But how much of what we’re hearing is real, and how much of it is hype? What are all the ways that hydrogen is being produced, what is the global capacity for producing it now, what kind of investment would be needed to its production up to the needed levels, and where does hydrogen have a clear and tangible edge over competing technologies or energy sources?
In this episode, we present part one of a two-part, three-hour interview with Dr. Simon Evans, the deputy editor and policy editor for Carbon Brief, in which he shares their findings from dozens of interviews they conducted with experts who are knowledgeable about hydrogen’s potential, as well as from dozens of research reports and other resources.
In this first part of the interview, we’ll talk about the expectations for Hydrogen Economy 2.0; 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 part 2 of this interview, which will run as Episode #143, we’ll talk about the various potential applications of hydrogen sector by sector and use 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. So stay tuned for that!
Dr. Simon Evans is the deputy editor and senior policy editor of CarbonBrief, where he covers climate and energy policy. He holds a PhD in biochemistry from Bristol University and previously studied chemistry at Oxford University. He worked for environment journal The ENDS Report for six years, covering topics including climate science and air pollution.
