Show Summary
On this episode, chemical engineer Paul Martin joins The Great Simplification to talk about all things hydrogen. There are many ‘Fuels of the Future’ about which the media likes to create hopeful and seamless narratives, one of the currently popular of these being hydrogen. Where does hydrogen come from and what do we already depend on hydrogen for – is it as ‘clean’ as the media leads us to believe? How can we think about hydrogen from a systems perspective to determine if it is really an energy solution – or an energy problem? What does this mean for the design of global supply chains entering into a simplified material future?
About Paul Martin
Paul Martin is a Canadian chemical engineer with decades of experience making and using hydrogen and syngas. As a chemical process development specialist, Paul offers services to an international clientele via his private consultancy Spitfire Research. He is also co-founder of the Hydrogen Science Coalition, a nonprofit organization providing science-based information about hydrogen from a position free from commercial interest.
