1. 1. Investigating the dynamics between the developing Nordic hydrogen market and the electricity system under uncertainty

   Master-uppsats, KTH/Energiteknik

   Författare :Timon Renzelmann; [2024]
   Nyckelord :energy modelling; energy storage; global sensitivity analysis; hydrogen; Method of Morris; Nordics; OSeMOSYS; uncertainty analysis; energimodellering; energilagring; global känslighetsanalys; vätgas; Morris-metoden; Nordiska länder; OSeMOSYS; osäkerhetsanalys;

   Sammanfattning : The potential of hydrogen as a clean energy carrier is hotly debated, but it promises to significantly contribute to a sustainable energy future. Hydrogen can replace fossil fuels in carbon-intensive industries, heavy transport and aviation, and support a renewable energysystem by acting as energy storage to balance intermittent supply.

3. 2. The Impact of an Offshore Wind Farm on a Power Grid

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Arvid Söderberg; Tim Possekel; [2023]
   Nyckelord :;

   Sammanfattning : Due to increasing power demands and growing importance of sustainability, more and morewind power is being built and connected to existing power systems. While wind power isboth renewable and cost-effective, it is important to note that due to its variable nature, itcan negatively impact the stability of a power system. LÄS MER

4. 3. Cannibalization of Renewable Energy in Spain: Market Implications and Mitigation Strategies through CArbon Pricing and Gurarantess of Origin

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

   Författare :Fredrik Lannhard; [2023]
   Nyckelord :Cannibalization; Renewable energy; Marginal pricing; Day-ahead markets; Spain; Electricity market simulation; Carbon pricing; Guarantees of origin.; Kannibalisering; Förnybar energi; Marginalprissättning; Spotmarknader; Spanien; Elmarknadssimulering; Koldioxidprissättning; Ursprungsgarantier.;

   Sammanfattning : Renewable cannibalization refers to the phenomenon where the increasing penetration of zeromarginal cost renewable energy sources, such as solar and wind power, leads to a decline in their market value. By extension, this threatens to reduce investment incentives in wind and solar. LÄS MER

5. 4. Deposition av Black carbon i sjöar efter den stora skogsbranden i Västmanland 2014

   Magister-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC); Lunds universitet/Miljövetenskaplig utbildning

   Författare :Danny Wong; [2023]
   Nyckelord :Black carbon; BC; climate; environment; wildfire; boreal forests; lake sediments; Västmanland.; Earth and Environmental Sciences;

   Sammanfattning : Black carbon (BC) is produced during incomplete combustion of Biomass and fossil fuels. BC and other carbonaceous pollutants have characteristics that affect the climate, environment, and human health. Historically, BC emissions have been measured and monitored in the atmosphere, and BC emissions to the air are quite well documented. LÄS MER

7. 5. Size effect in wood : Characterization of mechanical properties using digital image correlation method

   Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad mekanik

   Författare :Amir Saeidi; Olafur Johannsson; [2023]
   Nyckelord :compression test longitudinal direction; digital image corre- lation DIC ; ncorr; phyton; pinewood; size effect; stiffness matrix; wood- construction; YAWCAM; young’s modulus; digital image correlation DIC ; elasticitetsmodul; furu; kom- pressionstest längs fiberriktning; ncorr; phyton; storlekseffekt; styvhetsma- tris; trä-konstruktion; YAWCAM;

   Sammanfattning : As a natural composite material, wood exhibits complex structural char-acteristics and diverse behavior under compression and tensile forces. Itsanisotropic nature results in mechanical properties that vary depending onthe load direction along its longitudinal, tangential, and radial grains. LÄS MER
