The emergence of hydrogen and fuel cell technologies offers the world important and potentially transformative economic and energy security benefits.  In recent years, research supported by the U.S. Department of Energy’s (DOE) Fuel Cell Technologies Office has contributed substantially to the development of these technologies.  The research investments to reduce costs in fuel cell stacks over the past 15 years have clearly paid off, as commercial fuel-cell electric vehicles (FCEVs) are being rolled out by major car manufacturers today.  With increasing market penetration of FCEVs, enabling technologies for the affordable and widespread production of hydrogen are becoming increasingly important.  Long term commercial viability of large-scale hydrogen production in the commercial marketplace will rely on continued materials research on several important fronts. Examples include the discovery and development of efficient and durable materials, devices and systems for photoelectrochemical water splitting powered by sunlight and high-temperature solar thermochemical water splitting.   Research innovations to advance the state-of-the-art in these areas are being facilitated by the DOE Energy Materials Network (EMN) initiative which aims to accelerate materials research and development for clean energy applications through the streamlined utilization of advanced scientific resources in theory, computation, experimentation, analysis, and data informatics.  Progress to date in “HydroGEN” EMN consortium research and development on advanced water splitting materials for industrial-scale hydrogen production will be described and discussed.
