Hydrogen is touted as a key component in energy transition, providing a carbon-free source of energy from transportation to heating our homes, while conveniently using existing oil & gas infrastructure and reserves. If so, why haven’t we built a hydrogen economy already? Is the hydrogen economy more hype than hope? What are its challenges from the immutable laws of thermodynamics, to technology, to safety and cost that have limited it to date?  And as the commodity community begins to focus on its, what questions need to be asked. Our guest is Paul Martin, a chemical process engineer with a long association with hydrogen and its uses. Paul, a well-known thinker and writer on energy transition, walks us through the science and why hydrogen might continue to play a minimal, even negative, role in the energy transition story. To find out more about HC and our talent advisory services in the energy & commodities sector visit www.hcgroup.global/hc-insider To connect with our host Paul Chapman, you can find him at www.linkedin.com/in/paulchapmanhc/
