Hydrogen (H2) is an important industrial chemical, produced at a global rate > 50 billion kg/year. Nearly all of this H2 is derived from fossil fuels using today’s conventional processes. Developing new pathways for the renewable production of H2 could play an important role in reaching sustainability goals for the globe.
Two particularly intriguing pathways to renewable H2 production include solar photoelectrochemical (PEC) water-splitting and PV-powered water electrolysis. This talk will describe advances in both areas, with a focus on the development of catalysts, semiconductors, and interfaces. Examples will include unassisted PEC water-splitting systems with different configurations, involving a range of semiconductor and catalyst materials, as well as non-precious metal catalyst development for PEM electrolysis.
