  1. 1. A Techno-Economic Framework for the Analysis of Concentrating Solar Power Plants with Storage

    Author : Rafael Guédez; Björn Laumert; Zhor Hassar; Viktoria Martin; Alberto Traverso; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concentrating solar power; thermal energy storage; techno-economic analysis; Termisk solkraft; termisk energilagring; techno-eknomiska analys; Energiteknik; Energy Technology;

    Abstract : Concentrating solar power plants can integrate cost-effective thermal energy storage systems and thereby supply controllable power on demand, an advantage against other renewable technologies. Storage integration allows a solar thermal power plant to increase its load factor and to shift production to periods of peak demand. READ MORE

  2. 2. Novel cycles using carbon dioxide as working fluid : new ways to utilize energy from low-grade heat sources

    Author : Yang Chen; Per Gunnar Lundqvist; Mats Westermark; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal energy engineering; Termisk energiteknik;

    Abstract : This licentiate thesis proposes and analyzes three carbon dioxide novel cycles, namely: the carbon dioxide transcritical power cycle, the carbon dioxide Brayton cycle and the carbon dioxide cooling and power combined cycle. Due to the different characteristics of each cycle, the three cycles are suitable for different applications. READ MORE

  3. 3. Enhanced boiling heat transfer from a novel nanodendritic micro-porous copper structure

    Author : Richard Furberg; Björn Palm; Mats Strömblad; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal energy engineering; Termisk energiteknik;

    Abstract : Following licentiate thesis is a summary of the advances made within the research project - Micro- and nano structured surfaces for enhanced boiling heat transfer – which is a collaboration effort between the Divi-sion of Applied Thermodynamics and Refrigeration and the Division of Materials Chemistry at the Royal Institute of Technology (KTH). The main objectives with this research project has been to: develop methods for producing highly efficient boiling surfaces with well defined micro- and nano-structured porous surfaces by the use of micro- and nano-manufacturing techniques.

    Abstract : While biomass utilization for energy conversion in the industrialized nations is being largely developed, highly efficient and environmentally friendly, many tropical countries still use biomass at low efficiencies and high emission levels. The main reasons for these gaps are both political and technological: the energy markets are different, the Gross National Product (GDP) differs widely, and the feedstock differs in form and conversion behaviour.
