2. 1. Hybrid Solar Gas-Turbine Power Plants : A Thermoeconomic Analysis

   Author : James Spelling; Andrew Martin; Björn Laumert; David Tomas Sanchez Martinez; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar thermal power; hybrid gas-turbine; thermoeconomics; koncentrerad solenergi; gas-turbiner; ekonomisk analys;

   Abstract : The provision of a sustainable energy supply is one of the most importantissues facing humanity at the current time, and solar thermal power hasestablished itself as one of the more viable sources of renewable energy. Thedispatchable nature of this technology makes it ideally suited to forming thebackbone of a future low-carbon electricity system. READ MORE

4. 2. A Thermoeconomic Evaluation of CO2 Capture with Focus on Gas Turbine-Based Power Plants

   Author : Björn Fredriksson Möller; Kraftverksteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; climate change; optimisation; genetic algorithms; applied thermodynamics; Thermal engineering; AZEP; GTPOM; gas turbine; CO2 capture; thermoeconomy; termodynamik;

   Abstract : The increasing emissions of carbon dioxide from fossil fuel burning are today thought to be one of the main contributors to global warming. At the same time, developing countries are striving for an increased welfare and burning more fossil fuel, which in turn is augmenting the greenhouse gas effect. READ MORE

5. 3. Reducing Carbon Emissions From Natural Gas-fired Power Plants – Biomass, Concentrated Solar and Carbon Capture

   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
