  1. 1. Water Purification : Research on the Energy Supply of Air Gap Membrane Distillation for Access to Clean Water

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik; KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Linda Yang; Robert Liao; [2020]
    Keywords : Air gap membrane distillation; water purification; energy system; Vattenrening; energisystem; luftspaltmembran;

    Abstract : Water stress is an ongoing problem in many places in the world, while the demand for clean and safe freshwater is growing due to the increasing population. In many developing countries, water supplies often are contaminated with arsenic, fluoride, etc. READ MORE

  2. 2. Renewable power generation for developing societies on a remote island in Fiji : A case study

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik; KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Erika Rebhan; Ellinor Wahnström; [2020]
    Keywords : Fiji; Moala Island; Renewable power generation; Remote electrification; HOMER software; Fiji; Moala; Förnybar kraftproduktion; Elektrifiering på avlägsna platser; HOMER-programvara;

    Abstract : Access to electricity is an important factor for rural development as many needs and services such as education, health care and water supply all have energy requirements. The aim of this study was to develop a sustainable electrification system based on renewable energy for the remote village Keteira on Moala Island, Fiji. READ MORE

  3. 3. Aerodynamic Design in Axial Turbine for Heavy Duty Applications

    University essay from Lunds universitet/Institutionen för Energivetenskaper

    Author : Eric Lennman; [2020]
    Keywords : Turbine design; MULTALL; Design methodology; Electric turbo compound turbine; Technology and Engineering;

    Abstract : Turbomachinery design is based on multiple physical thermodynamical relations and fluid mechanics. Software implementing these relations in computing fluid flows have been broadly accessible since the 1990’s and has also become more applied to turbomachinery design. READ MORE

  4. 4. Techno-economic analysis of Battery Energy Storage Systems and Demand Side Management for peak load shaving in Swedish industries

    University essay from KTH/Kraft- och värmeteknologi; KTH/Kraft- och värmeteknologi

    Author : Benjamin Skog Nestorovic; Douglas Lindén; [2020]
    Keywords : Peak load shaving; battery energy storage system; demand side management; Fast Frequency Reserve market; power tariff; Effektoppsreducering; batterilagringssystem; efterfrågeflexibilitet; Fast Frequency Reserve; effekttariffer;

    Abstract : The Swedish electrical grid has historically been robust and reliable, but with increased electrification in numerous sectors, out-phasing of nuclear power and a high market diffusion of wind power, the system is now facing challenges. The rotational energy in the system is expected to decrease as a result of higher shares of intermittent energy sources, which can affect the stability of the grid frequency negatively. READ MORE

  5. 5. Feasibility Study of the Decarbonisation and Electrification of a Commuter Ferry in Stockholm city

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Matilda Helgesson; [2020]
    Keywords : Fuel cells; Fuel cell hybrid; HVO; Li-ion battery; techno-economic analysis; Bränslecell; HVO; bränslecellshybrid; Li-jon batteri; teknoekonomisk analys;

    Abstract : There is a need for alternative marine fuels and propulsion techniques in order to reduce the environmental and climate impacts of the transport sector, and meet the new Swedish climate targets of net zero emissions by 2045. There are several projects and studies on full electric ferries, while the option of hydrogen fuel cell-battery hybrids are not as well explored. READ MORE
