Description
Summary:Energy is the most important issues of social and economic life in countries either developed or just developing. It is very well known that hydrogen energy, which is the most advanced energy carrier; environmental friendly and sustainable, can compensate the increasing energy requirements. The generation of hydrogen through electrolysis possessed several advantages, such as high efficiency, low pollutant emissions and flexible fueling strategies. This research aims to create an efficient, effective and multi-disciplinary solution package to produce hydrogen evaluating the waste heat. The main goal of this research was to increase the efficiency of hydrogen production by operating the Solid Oxide Electrolysis Cell (SOEC) at an optimum combination of operating conditions. Number of electrolysis cell, the number of stacks and cell area which are the parameters that affect the high temperature electrolysis are determined on the basis of previous studies. Steam temperature and steam flow rate that are calculated parametrically for the system. •To create an effective solution package to produce hydrogen.•Improve hydrogen production efficiency through a SOEC.•Effects of ASR and SU are analyzed for flue gas temperature vs. hydrogen production, electrolysis voltage and current density.
