This webinar introduces a refined and updated view of the concept of the colours of hydrogen based on a survey of many recent reports and roadmaps on hydrogen. As a versatile, colourless molecular energy carrier with great potential to decarbonize multiple sectors and help reach net-zero emissions, there has been a renewed interest in improving and expanding hydrogen production with minimal or zero impact to the environment.

The conventional wisdom to categorize hydrogen production methods relies on colours that are associated with the technology pathways and their net carbon-emission impact. Despite some confusion arising from ill-defined associations, the concept of hydrogen colours has been gaining popularity due to the simplicity of such associations. This talk aims to de- mystify these colours by embodying an expanded palette that reflects both existing and emerging (advanced) pathways to contribute to the ongoing conversation, and efforts toward promoting and supporting the research, policy and regulations on realizing the clean hydrogen vision.

Dr Ahmet Kusoglu is a staff scientist at Lawrence Berkeley National Laboratory (LBNL), working on polymeric and functional materials for hydrogen and clean energy applications. His research focuses on the characterization of ion-conductive polymers and solid-electrolyte interfaces for energy conversion and storage devices, and related electrochemical-mechanical phenomena. He received his PhD from the University of Delaware and did his postdoctoral research at LBNL on fuel-cell membranes. He has published more than 70 peer-reviewed journal papers and two book chapters, and given more than 30 invited talks and tutorials at international meetings, academic and industry forums. He is the recipient of the 2017–2018 ECS Toyota Young Investigator Fellowship and 2016 ECS Srinivasan Young Investigator Award. He participated in Department of Energy Consortia on Hydrogen including HydroGEN, FC-PAD, and H2NEW. Kusoglu served as the thrust co-ordinator in the Fuel Cell Performance and Durability Consortium, and is currently communications director of the Million Mile Fuel Cell Truck (M2FCT) Consortium. His interests include data-driven material design, decarbonization of transportation and data visualization.
