This paper discusses new hydrogen production methods that have been actively investigated both theoretically and experimentally at UOIT and some recent findings through experimental measurements and analysis. A major cluster of activities at UOIT has developed novel hydrogen production systems from electrolysis to thermochemical cycles and from integrated cycles to solar-light based hydrogen production processes. The results confirm that both thermochemical cycles and photochemical processes offer promising potential for sustainable hydrogen production. Copyright (C) 2014, Hydrogen Energy Publications, LLC.
