Evaluation Of Solar Energy Solution For Egyptian Remote Areas, Tarek Ihab Abdelsalam, Tarek M. Hatem Jan 2014

Evaluation Of Solar Energy Solution For Egyptian Remote Areas, Tarek Ihab Abdelsalam, Tarek M. Hatem

Mechanical Engineering

Egypt is currently suffering the symptoms of the energy crises, such as electricity outage and high deficit as a result of constant increase in fossil foils through the last decades. On the other hand, Egypt has a high solar availability of more than 18.5 MJ annually. Additionally, Egypt has large uninhabited deserts on both sides of the Nile valley and in Sinai Peninsula, which represent more than 96.5% of the nation’s total land area. Therefore, solar energy is one of the prospective solutions for energy shortage in Egypt. Furthermore, these vast lands are advantageous for commissioning huge solar power generation …


Modelling Of Biomass Gasification Integrated With A Solid Oxide Fuel Cell System, Wayne Doherty Jan 2014

Modelling Of Biomass Gasification Integrated With A Solid Oxide Fuel Cell System, Wayne Doherty

Doctoral

Biomass is of major interest as a renewable energy source in the context of climate change and energy security. Traditional biomass conversion technologies achieve low electrical efficiencies. Biomass gasification (BG) coupled with fuel cells offer higher efficiencies. Gasification is a process in which a carbonaceous fuel is converted to a combustible gas. It occurs when a controlled amount of oxidant is reacted at high temperatures with available carbon in a fuel within a gasifier. Two technologies (circulating fluidised bed air gasification and dual fluidised bed steam gasification) were modelled. Solid oxide fuel cells (SOFCs) are well suited to integration with …
