2. 1. Modelling of Solid Oxide Fuel Cells Applied to the Analysis of Integrated Systems with Gas Turbines

   Author : Azra Selimovic; Kraftverksteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; statistical physics; plasma; plasmas; Gaser; fluiddynamik; Termisk teknik; termodynamik; Gases; fluid dynamics; applied thermodynamics; Thermal engineering; Hybrid Cycles; Gas Turbines; Mathematical Modelling; Electrochemistry; Fuel Cells; Solid Oxide Fuel Cells; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; kvantmekanik; relativitet; gravitation; statistisk fysik; Mathematical and general theoretical physics; classical mechanics; quantum mechanics; relativity;

   Abstract : Solid oxide fuel cells (SOFCs), working at high temperatures with an incomplete fuel oxidation process, have become an interesting candidate for combination with conventional power generation technology, such as gas turbines, in order to develop power plants that are both functional and efficient. An absolute condition for successful analysis and optimisation of such plants is the existence of reliable simulation tools. READ MORE

4. 2. Generation of synthesis gas for fuels and chemicals production

   Author : Per Tunå; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synthetic fuels and chemicals; gasification; gas conditioning; simulation; tar-cracking;

   Abstract : Many scientists believe that the oil production will peak in the near future, if the peak has not already occurred. Peak oil theories and uncertain future oil deliveries have stimulated interest in alternative sources of fuel and chemicals. READ MORE

5. 3. Thermal detector with integrated absorber structure for mid-IR gas detection

   Author : Shakeel Ashraf; Göran Thungström; Peter Enoksson; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal detectors; Thermopile detectors; Infrared absorbers; SU-8 epoxy; Interferometric and Multi-layered absorber; Seebeck coefficient; Molybdenum di-sulfide;

   Abstract : Measurement of the concentration of greenhouse gases, such as carbon dioxide(CO 2 ) and methane (CH 4 ), in the atmosphere has received significant attention in the last few decades. This work focusses on the development of high-performance thermopile detectors for use with the non-dispersive infrared (NDIR) measurements of such gases. READ MORE

6. 4. Cost-efficient integration of variable renewable electricity - Variation management and strategic localisation of new demand

   Author : Viktor Walter; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flexibility measures; Energy system modelling; smart energy systems; variation management strategies; variable renewable electricity;

   Abstract : The aim of this work was to improve our understanding of how wind power and solar photovoltaics (PV) can be integrated into the European electricity system in a cost-efficient manner. For this, a techno-economic, cost-minimising model of the electricity system is refined for a number of case studies. READ MORE

7. 5. European Energy Policy in Transition: Critical Aspects of Emissions Trading

   Author : Markus Wråke; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Energy policy; climate policy; carbon dioxide; climate change; emissions trading; EU ETS; efficiency; distributional effects; closures; new entrants; electricity; allocation; auctions; carbon leakage; competitiveness; peat; radiative forcing;

   Abstract : The overarching theme of the thesis is European energy and climate policy, with a particular focus on the role of emissions trading. The thesis consists of eight papers. Paper 1 outlines the origins and characteristics of the European Union’s Emissions Trading System (EU ETS), launched in January 2005. READ MORE
