Solar hydrogen production by photovoltaic near Cairo, Egypt from theoretical and experimental point of view

There is a common understanding, between many scientists and engineers, that solar hydrogen is one of most suitable carriers, for the technological and environmental problems of the earth, and knowing the limitation of the seen, to satisfy the world energy needs of future. Most studies on solar hydrogen systems have concentrated on the development of advanced electrolysers for solar operation and on the optimal coupling of a PV-array to electrolyser to maximize the annual H-2 production. In this paper, it has been shown that, the development of equivalent electrical and thermal models for solar hydrogen subsystems to get a closer insight into the transient response behavior of these elegants, and to estimate the overall system performance.
