    A research on hydrogen production from industrial waste heat by thermal water splitting
    (Pergamon-Elsevier Science Ltd, 2016) Toklu, Ethem; Avcı, Arzu Coşkun; Kaygusuz, Kamil; Gür, Mahmut
    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. (C) 2016 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.

    Sustainable Agriculture and the Production of Biomass for Energy Use
    (Taylor & Francis Inc, 2011) Durusoy, I.; Türker, Mustafa Fehmi; Keleş, Sedat; Kaygusuz, Kamil
    Modern bioenergy is seen as a promising option to curb greenhouse gas emissions. There is, however, a potential competition for land and water between bioenergy and food crops. Another question is whether biomass for energy use can be produced in a sustainable manner given the current conventional agricultural production practices. Other than the land and water competition, this question is often neglected in scenarios to meet a significant part of global energy demand with bioenergy. There are sustainable alternatives, for example organic agriculture, to avoid the negative environmental effects of conventional agriculture. Yet, meeting a significant part of global energy demand with biomass grown sustainably may not be possible, as burning significant quantities of organic matter is likely to be incompatible with the principles of such alternatives, which often rely on biomass input for nutrient balance. There may, therefore, be a trade-off between policies and practices to increase bioenergy and those to increase sustainability in agriculture via practices, such as organic farming. This is not a general critique of bioenergy but it points to additional potential dangers of modern bioenergy as a strategy to meet significant parts of world energy demand.
