Process Simulation Of Biomass Gasification Integrated With A Solid Oxide Fuel Cell Stack, Wayne Doherty, Anthony Reynolds, David Kennedy
Process Simulation Of Biomass Gasification Integrated With A Solid Oxide Fuel Cell Stack, Wayne Doherty, Anthony Reynolds, David Kennedy
Articles
Biomass gasification-solid oxide fuel cell (BG-SOFC) combined heat and power (CHP) systems are of major interest in the context of climate change mitigation, energy security and increasing energy efficiency. Aspen Plus is employed to simulate various BG-SOFC CHP systems. The aim of the research work is to investigate the technical feasibility of these systems and to study the influence of important operating parameters and examine integration options. Systems based on dual fluidised bed steam gasification and tubular SOFC technologies are modelled. The cathode recycle and electric heater integration options are not attractive in comparison to the base case anode recycle …
Optimised Integration Of Grid-Connected Renewable Energy Technologies For Domestic Application In Ireland, Zhe Li
Doctoral
The utilisation of renewable energy resources for electricity and thermal generation is extremely important in Ireland due to the lack of indigenous fossil fuel resources and the high dependence on imported fossil fuels. The release of environmentally-damaging greenhouse gases in the combustion of fossil fuels in electricity and thermal generation is also a major issue. In Ireland, the domestic dwelling is recognised as one of the biggest energy consumers. The use of renewable energy technologies to provide electricity, heating and hotwater can effectively offset the usage of fossil fuels. The aim of this research study was to develop a novel …
A Collagen‐Glycosaminoglycan‐Fibrin Scaffold For Heart Valve Tissue Engineering Applications, Claire Brougham, Stefan Jockenhoevel, Thomas Flanagan, Fergal O'Brien
A Collagen‐Glycosaminoglycan‐Fibrin Scaffold For Heart Valve Tissue Engineering Applications, Claire Brougham, Stefan Jockenhoevel, Thomas Flanagan, Fergal O'Brien
Conference Papers
The field of heart valve biology and tissue engineering a heart valve continue to expand. The presentatio ns at this meeting reflect the advances made in both areas due to the multi-disciplinary approach taken by many laboratories.
Sustainable Business Development: An Irish Perspective, Tony Kealy
Sustainable Business Development: An Irish Perspective, Tony Kealy
Conference Papers
This research investigates the current status of sustainable business development practises in Ireland using qualitative analysis on data obtained from semi-structured interviews. The thirteen interviewees were chosen to represent a wide spectrum of influential organisations in Irish society and included private businesses, charity organisations, faith-based organisations, farmer associations, and government representatives. Analysis of the findings confirmed that the three well established key elements that must be considered if businesses are to be developed in a sustainable way, namely Profit, People, and Planet are still valid. However, this research also found that there were other elements important for developing sustainable business. …
Applied Energy Systems - Rudimentary Thermodynamics, Jim Mcgovern
Applied Energy Systems - Rudimentary Thermodynamics, Jim Mcgovern
Book/Book Chapters
This is a compact textbook for a module addressing rudimentary thermodynamics within the context of applied energy systems. It is at an introductory level for engineers or technologists. The book does not attempt to cover the principles of thermodynamics comprehensively. Rather, it provides a practical but theoretically sound foundation, linked to some key areas. Energy, heat and work are all introduced, as are units and dimensions. Ideal gases and properties of liquids and vapours are treated. Non-flow and steady flow processes are described. Simple theory is provided for pumps and for the reciprocating compressor. Rudimentary steam and refrigeration or heat …
Economic, Energy And Ghg Emissions Performance Evaluation Of A Whispergen Mk Iv Stirling Engine Μ-Chp Unit In A Domestic Dwelling, Gerry Conroy, Aidan Duffy, Lacour Ayompe
Economic, Energy And Ghg Emissions Performance Evaluation Of A Whispergen Mk Iv Stirling Engine Μ-Chp Unit In A Domestic Dwelling, Gerry Conroy, Aidan Duffy, Lacour Ayompe
Articles
This paper presents an assessment of the energy, economic and greenhouse gas emissions performances of a WhisperGen Mk IV Stirling engine μ-CHP unit for use in a conventional house in the Republic of Ireland. The energy performance data used in this study was obtained from a field trial carried out in Belfast, Northern Ireland during the period June 2004 - July 2005 by Northern Ireland Electricity and Phoenix Gas working in collaboration with Whispertech UK. A comparative performance analysis between the µ-CHP unit and a condensing gas boiler revealed that the µ-CHP unit resulted in an annual cost saving of …
Modelling Of Biomass Gasification Integrated With A Solid Oxide Fuel Cell System, Wayne Doherty
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 …
Educational Programmes For Spatial Information Sciences In The Technological University Of Dublin, William Prendergast, Eamonn Murphy, Audrey Martin, Avril Behan
Educational Programmes For Spatial Information Sciences In The Technological University Of Dublin, William Prendergast, Eamonn Murphy, Audrey Martin, Avril Behan
Conference papers
The ever increasing spatial information needs of society, the rapid development of new surveying technologies, and the global demand for appropriately qualified surveyors, have triggered a radical re-evaluation of geomatics education worldwide. Significant enhancements have been made to the educational programmes in the spatial information science discipline in the Technological University of Dublin’s (DIT) during the last decade including the provision of a BSc in Geomatics and various masters’ programmes to cater for the increasingly specialised needs of the Geographic Information sector in Ireland.
