  2. 6. Electricity access for human development in the Brazilian Amazon

    Author : Maria F Gómez; Semida Silveira; Elisabeth Ilskog; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electricity access; human development; Amazon region; SRA - Energy; SRA - Energi;

    Abstract : Electricity access is widely recognized as a driver of development. The Brazilian government has incorporated this principle into its national rural electrification program, Luz Para Todos (LPT – Light for all), which has already benefited more than 14 million people in the country since its inception in 2003.

  4. 7. Atomistic Modelling of Materials for Clean Energy Applications : hydrogen generation, hydrogen storage, and Li-ion battery

    Author : Zhao Qian; Rajeev Ahuja; Börje Johansson; Antonio Ferreira da Silva; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Renewable energy; Materials science; Hydrogen production; Hydrogen storage; Li-ion battery; Density functional theory; SRA - Energy; SRA - Energi; SRA - E-Science SeRC ; SRA - E-vetenskap SeRC ;

    Abstract : In this thesis, a number of clean-energy materials for hydrogen generation, hydrogen storage, and Li-ion battery energy storage applications have been investigated through state-of-the-art density functional theory.As an alternative fuel, hydrogen has been regarded as one of the promising clean energies with the advantage of abundance (generated through water splitting) and pollution-free emission if used in fuel cell systems.

  5. 8. Thermodynamic and Kinetic Investigation of the Fe-Cr-Ni System Driven by Engineering Applications

    Author : Wei Xiong; Malin Selleby; John Ågren; Byeong-Joo Lee; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase transformation; magnetism; spinodal decomposition; stainless steel; low temperature CALPHAD; phase field; ab initio; atom probe tomography; calorimetry; SRA - E-vetenskap SeRC ; SRA - E-Science SeRC ; SRA - Energy; SRA - Energi;

    Abstract : This work is a thermodynamic and kinetic study of the Fe-Cr-Ni system as the core of stainless steels. The Fe-Cr, Fe-Ni and Cr-Ni systems were studied intensively using both computational and experimental techniques, including CALPHAD (CALculation of PHAse Diagrams), phase field simulation, ab initio modeling, calorimetry, and atom probe tomography.

  6. 9. Enhancing the Treatment of Systems Integration in Long-term Energy Models

    Author : Manuel Welsch; Mark Howells; Erik Ahlgren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system models; Energy system models; Resource system models; Smart Grids; Operating reserve; Biofuels; Sub-Saharan Africa; Ireland; Mauritius; ; kraftsystemmodeller; energisystemmodeller; resursmodeller; smarta elnät; operativ reservkapacitet; biobränslen; Afrika söder om Sahara; Irland; Mauritius; ; SRA - Energy; SRA - Energi;

    Abstract : Securing access to affordable energy services is of central importance to our societies. To do this sustainably, energy systems design should be – amongst other things – environmentally compliant and reconcile with the integrated management of potentially limiting resources. READ MORE

  7. 10. Design of Internal Cooling Passages: Investigation of Thermal Performance of Serpentine Passages

    Author : Waseem Siddique; Torsten Fransson; Bengt Sundén; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas turbine; heat transfer; CFD; Serpentine passages; SRA - Energy; SRA - Energi;

    Abstract : Gas turbines are used to convert thermal energy into mechanical energy. The thermal efficiency of the gas turbine is directly related to the turbine inlet temperature. READ MORE
