  1. 1. If Trees Could Talk - Dendrochemistry, a Promising Method for Understanding Pollution History

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Jonatan Uusitalo; [2023-08-17]
    Nyckelord :;

    Sammanfattning : Heavy metal pollution presents a significant environmental challenge in the Anthropocene era, and understanding pollution history is crucial to address historical pollution and implementing effective mitigation measures. This study stands among a few comprehensive dendrochemical investigations that utilized an extensive dataset and energy dispersive X-ray fluorescence (EDXRF) technique to reconstruct the contamination history of As, Cd, Cu, Ni, Pb, and Zn, with a focus on Cu.

  4. 3. Study on feasibility of small-scale pumped hydro storage- A case study in Sweden

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Prashant Niroula; [2023]
    Nyckelord :energy storage; pumped hydropower; electricity market; investment; new technologies; feasibility; Technology and Engineering;

    Sammanfattning : The European union has been aggressively pushing forward with policies favoring renewable sources of energy. As a result, the share of intermittent renewables in the European power grid is rising and is expected to grow even more in the coming decade. The Swedish energy agency also forecast huge growth in wind power. LÄS MER

  5. 4. Energilagring med pumpkraft i gruvor : En utredning av potentialen för långtidslagring i Sveriges energisystem

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Alexandra Sederholm; Sophie Ågren; [2022]
    Nyckelord :Long-term Energy Storage; UPHES; Pumped hydro; Energilager;

    Sammanfattning : This thesis is divided in two sections. The first part consists of an interview study with 10 participants to investigate how the industry views the demand for energy storage and how it may develop in the future. Although some views differed, the study showed that a great responsibility lies on the existing hydropower. LÄS MER

  7. 5. Geochemical tracing of Arsenic sources in groundwater at the remediated Storliden mine, Skellefte district

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser
