  1. 16. Life cycle assessment of coal based direct-reduced iron production in India

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : SABARISH ELANGO; [2020]
    Keywords : ;

    Abstract : The production of iron through direct reduction (Direct-Reduced Iron; DRI) involves the use of natural gas or coal to reduce iron ore to iron through carbothermic reactions at a temperature below its melting point, negating the need for a blast furnace as otherwise required. In India, around 25% of iron is produced through direct reduction. READ MORE

  3. 17. Detailed chemical abundances of neutron-capture elements - from 523 local giant stars

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Rebecca Forsberg; [2019]
    Keywords : The Milky Way galaxy; Abundances; High-resolution spectroscopy; Neutron-capture elements; Physics and Astronomy;

    Abstract : Purpose: The purpose of this work is to determine the abundances of neutron-capture elements in solar neighborhood giant stars. This enables constraints to be put on the the cosmic origin of these elements. READ MORE

  4. 18. OPTIMAL ENERGY DESIGN FOR A SYSTEM OF PUMPED HYDRO-WIND POWER PLANTS

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : LAKSHMI NAGA SWETHA YANAMANDRA; [2018]
    Keywords : Pumped Hydro; Wind farm; Energy Storage; Renewable Energy.;

    Abstract : SAMMANFATTNING Medvetenhet och oro kring miljöeffekter från utsläpp av växthusgaser och de minskande resurserna av icke förnybara energikällor har ökat de senaste årtiondena. Utvecklingen av ny teknologi för förnybar energi har drivits fram globalt som ett svar på denna oro. READ MORE

  5. 19. Investigation of the properties of thin films grown via sputtering and resistive thermal evaporation : an Ion Beam Analysis (IBA) study

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Markus Back; [2015]
    Keywords : Thin film; sputtering; evaporation; RBS; ERDA;

    Abstract : In this project, thin films are being manufactured by different methods in a thin film deposition set-up and subsequently characterized. This is done in order to determine if the set-up is capable of producing films of sufficient quality to be used for research purposes in the ion physics group of the division of applied nuclear physics at Uppsala University.

  6. 20. Energy flow in a Hybrid Wind/ Hydrogen System for Kampala and Tororo towns in Uganda

    University essay from KTH/Energiteknik

    Author : GODFREY SSAJJA SSALI; [2015]
    Keywords : ;

    Abstract : This report presents modeling for energy flow of a distributed renewable energy system based on an integrated wind power and hydrogen production system supplying a local electric load connected to an electric grid. The system consists of a 200kW wind generator, an Electrolyzer with a maximum production capacity of 5kg of hydrogen per 24h and a 3. READ MORE
