  1. 1. Using a GIS to enable an economic, land use and energy output comparison between small wind powered turbines and large-scale wind farms: the case of Oslo, Norway.

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Colin Potter; [2023]
    Nyckelord :Geography; GIS; Wind power; Renewable energy sources; urban wind energy; urban areas; planning; vertical axis wind turbines; comparative studies; urban integrated energy systems; Oslo; Roan; Earth and Environmental Sciences;

    Sammanfattning : Responding to an identified knowledge gap, the study aims to determine if smaller wind turbines located on top of existing urban buildings are more resource efficient (land utilization and economically) than large scale wind farms. To answer this question, using a GIS, the resource efficiency of the Roan wind farm in Northern Norway was compared to a theoretical modeled installation of small-scale wind turbines on top of buildings within a 2km radius study zone in central Oslo.

  3. 2. Methane Sulphonic Acid in East Antarctic Coastal Firn and Ice Cores and Its Relationship with Chlorophyll-a and Sea Ice Extent in the Southern Ocean

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Emma Nilsson; [2022]
    Nyckelord :methane sulphonic acid; firn cores; sea ice proxy; marine primary productivity; Fimbul Ice Shelf; Dronning Maud Land; metansulfonsyra; firnkärnor; havsis-proxy; marin primärproduktion; Fimbulisen; Dronning Maud Land;

    Sammanfattning : The seasonal retreat of sea ice in the austral spring and summer around Antarctica has a significant effect on phytoplankton activity, mainly due to light availability, meltwater input of dissolved iron, and surface water stratification. Phytoplankton produce dimethylsulfoniopropionate, the precursor to the climate-cooling gas dimethyl sulphide, which is ventilated to the atmosphere and oxidised to methane sulphonic acid (MSA).

  4. 3. Kommunernas klimatanpassning till framtida värmeböljor i Sverige

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Johanna Åström; [2022]
    Nyckelord :heat waves; extreme heat; climate change; climate change adaptation; adaptive capacity; risk management; resilience; elderly; public health; municipalities; local governance; Earth and Environmental Sciences;

    Sammanfattning : Extreme temperatures are increasing in frequency as well as intensity due to human induced climate change. Heat waves now pose a very high risk to the public health in Sweden and the elderly are particularly vulnerable. This study therefore aimed to investigate how Swedish municipalities are working to strategically manage these health risks. LÄS MER

  5. 4. Data center cooling solutions : A techno-economical case study of a data center in Sweden

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Joel Sjökvist; Fredrik Magnusson; [2022]
    Nyckelord :Energy systems; Data center cooling; Free cooling; Air cooling; Geothermal cooling; Mechanical cooling; District cooling; Building conversion; Dry cooler; Cooling machine; Borehole; PUE;

    Sammanfattning : Given the coinciding growth-trend in the production of consumer electronics and generation of data, the increase in server halls and data centers, as a means for hosting storage capacity for the generated data, has been prominent over the last decades. The establishment of data centers in already existing infrastructure can entail major changes in terms of energy system design. LÄS MER

  7. 5. Fjärrkylaproduktion med en BECCS-förvätskningsanläggning

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Domenique Silverstolpe; [2021]
    Nyckelord :förvätskning; koldioxid; fjärrkylaproduktion; liquefaction; BECCS; regional cooling;

    Sammanfattning : Energibolaget Stockholm Exergi (SE) har satt upp målet att driva en klimatpositiv verksamhet till 2025. För att möta miljömålet planerar företaget att bygga en BECCS-anläggning (Bio Energy Carbon Capture and Storage) till kraftvärmeverket KVV8 där biogen koldioxid avskiljs med HPC-absorption (Hot Potasium Carbonates).
