Clean Hydrogen Energy Systems for Better Environment and Sustainability
by Ibrahim Dincer
As we face great challenges about three primary Es (such as Energy, Environment and Economy), we need a critical solution to move into a non-carbon based economy which is impossible to achieve it without hydrogen. Of course, hydrogen is not a freely available element, and we essentially need disassociate it from water, although there numerous other hydrogen sources which are potentially considered by many. In this presentation, a focus is made on renewable energy based hydrogen production systems, particularly on thermochemical cycles and photoelectrochemical processes, and their developments, assessments and performance evaluations for various applications. Numerous cases studies and project results are presented to highlight the importance of innovative hydrogen production methods for better sustainability. Comprehensive life cycle assessment results are also presented to discuss the spectrums of various applications and implications.
