  1. 1. Integrating Waste Heat from Hydrogen Production Into District Heating

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Fawzi Kayali; [2023]
    Nyckelord :Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

    Sammanfattning : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. LÄS MER

  3. 2. Unlocking the Potential of Solar-Hydro Hybrid Solutions: Feasibility and Economic Analysis

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Måns Rosberg; [2023]
    Nyckelord :Hydropower; Solarpower; Hybrid power production; Solar-hydro hybrid power; Reservoir storage; Energy storage; Pumped hydro power; Floating PV; PV; Photovoltaics; Technology and Engineering;

    Sammanfattning : Hybrid solutions that combine multiple renewable energy sources, such as solar power and hydro power, are gaining popularity as a means of meeting the growing energy demands while minimising environmental impacts, but also as an opportunity of connecting solar power plants to the grid in areas where this might not be possible unless large investments are made. This master thesis aims to evaluate the feasibility and economic viability of integrating solar panels with an existing grid connection point at a hydro power plant, along with the introduction of an energy storage solution using a hydro power plant reservoir.

  4. 3. Goncharov and Collaborative Storytelling : How Tumblr Invented a Fake Martin Scorsese Movie

    Master-uppsats, Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

    Författare :Anna Birna Turner; [2023]
    Nyckelord :goncharov; tumblr; transmedia; storytelling; ARG; social media; fandom;

    Sammanfattning : Online fandoms are capable of various feats; from influencing the TV shows they watch to funding half-baked convention scams, Tumblr fandoms in particular are infamous across the internet. Their chaotic and intense nature simultaneously leads to intense bouts of creative activity, pumping hundreds of thousands of fan works into the Tumblr ecosystem every year. LÄS MER

  5. 4. Trimning av öppet pumphjul mot insatsring

    M1-uppsats, KTH/Produktionsutveckling

    Författare :Amina Mehmedovic; Ehsan Nabizade; [2023]
    Nyckelord :Water pump; open impeller; insert ring; trimming; Vattenpump; öppet pumphjul; insatsring; trimning;

    Sammanfattning : En lämplig pumpanordning är avgörande för hantering av stora mängder vatten. I det här arbetet kommer fokus ligga på pumpar som består av öppna pumphjul. Vid montering av pumpen bildas en spalt mellan insatsring och pumphjul, som bör ligga inom intervallet 0,5–0,8 mm för optimal effekt. LÄS MER

  7. 5. Barium in the O horizon of soils near Sundsvall, northern Sweden : From local minerals or from anthropogenic emissions?

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Mattias Åsberg Gencturk; [2023]
    Nyckelord :Barium; soil; organic horizon;

    Sammanfattning : Concentrations of potentially toxic metals in surface soils are important to investigate before building new residential areas. Prior to development of a residential area in Sundsvall, northern Sweden, it was observed that barium (Ba) concentrations in the soil at the site exceeded the guideline value of 200 mg kg-1 outlined by the Swedish Environmental Protection Agency.
