1. 1. Design of a Sustainable Energy System for a Community Center in rural Mozambique : A Minor Field Study in Mozambique

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

   Author : Emilia Säll Magnusson; Melchior Hahn; [2023]
   Keywords : Sustainable energy system; Solar PV system; off-grid; Community center; Rural Mozambique; Minor Field Study; Project Vita; Hållbart energisystem; Solcellssystem; off-grid; kultur- och fritidscentrum; Mozambiques landsbygd; Minor Field Study; Project Vita;

   Abstract : Access to energy is an important part in the development of most countries and societies, linked to both social and economic growth. Nevertheless, 70% of the population in sub-Saharan Africa does not have access to electricity, which brings consequences to several of these areas. READ MORE

3. 2. Mechanical properties of SiC nanowires with polytypes

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Anders Vesti; [2019]
   Keywords : atomistic modeling; nanowires; molecular dynamics; simulation; SiC; silicon carbide; fracture behavior; nanomechanics; Physics and Astronomy;

   Abstract : In this report, we model the mechanical properties and fracture behavior of SiC nanowires with different polytypes using Molecular Dynamics (MD) simulations. The mechanical properties investigated are the Young’s modulus, the maximum tensile stress and the fracture strain. The three polytype tested are SiC (3C), (2H) and (4H). READ MORE

4. 3. Grid impact study of frequency regulation with EVs

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Emma Blomgren; [2018]
   Keywords : Electric vehicles EVs ; grid impact; ancillary services; frequency regulation; FCR-N; vehicle-to-grid V2G ; voltage; reactive power; load profile; Technology and Engineering;

   Abstract : The ongoing grid paradigm shift has resulted in synchronous generators currently being phased out. As the generators have been providing ancillary services, such as frequency control regulation, this means that new technologies to perform ancillary services need to be developed and evaluated.

5. 4. Orust : en klimat- och energineutral ö? : möjligheter och hinder

   University essay from SLU/Dept. of Energy and Technology

   Author : Saga Palmquist; [2016]
   Keywords : klimatneutralt samhälle; energineutralt samhälle; Orust kommun; energiomställning; CO2-beräkningar;

   Abstract : Idag handlar en av de största globala debatterna om klimatförändringar. Sveriges regering har satt upp målet att Sverige år 2050 ska vara ett klimatneutralt land. För att kunna nå målet ett klimatneutralt Sverige är det viktigt att kommuner och invånare tillsammans arbetar för ett samhälle med minskade växthusgasutsläpp. READ MORE

6. 5. Fabrication of a light-weight SOFC using ceramic fibre paper as substrate

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Philip Löfkvist; [2015]
   Keywords : inorganic chemistry; solid oxide fuel cell; unmanned aerial vehicle; high temperature heat treatment; yttria stabilized zirconia; ceramic fibre paper; catator; nickel oxide; impregnation; paste manufacturing; ultra-sonication; ball-milling; optical microscopy; materials chemistry; scanning electron microscopy; materialkemi; Technology and Engineering;

   Abstract : A novel method for the fabrication of a light-weight solid oxide fuel cell (SOFC) has been evaluated at Catator. This was conducted in order to lower the weight and thus cost of an unmanned aerial vehicle. The main aim for this thesis was to achieve a thin, dense and crack-free electrolyte using a ceramic fibre paper as substrate. READ MORE
