  1. 1. Possibility for Positive Energy Retrofit in Borlänge

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Daniel Nay Myo Tun; Abideen Olaide Bakare; [2023]
    Keywords : ;

    Abstract : The built environment accounts for 40% of annual carbon dioxide (C02) emissions. Among the total emissions, building operations generate approximately 27% annually. Other than this, building materials, infrastructural materials, and construction (embodied carbon) contribute to an additional 13% annually [1]. READ MORE

  3. 2. Interfacial Dynamics at Surface Modified Molecular/Perovskite Solar Cells : How measurements are made to understand solar cell stability

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Benjamin Verbeek; [2023]
    Keywords : perovskite; solar cell; solar; energy; XPS; synchrotron;

    Abstract : Humanity has great energy demands, and must simultaneously combat climate change by curbing anthropogenic greenhouse gas emissions. Perovskite solar cells (PSC) provide a low-carbon energy source, at lower production costs than traditional silicon-based solar cells. PSC's suffer some issues with long-term stability. READ MORE

  4. 3. Robust BECCS deployment strategies under deep uncertainty : A case study of Stockholm Exergi

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Oscar Stenström; [2023]
    Keywords : Bioenergy carbon capture and storage; BECCS; decision making under deep uncertainty; DMDU; Dynamic Adaptive Planning; DAP; Robust Decision Making; RDM; Bioenergy carbon capture and storage; BECCS; decision making under deep uncertainty; DMDU; Dynamic Adaptive Planning; DAP; Robust Decision Making; RDM;

    Abstract : The most recent IPCC assessment shows that negative emissions (NEs) and carbon dioxide removal (CDR) technologies are becoming increasingly important in scenarios that limit global warming to 2 °C or lower. In these scenarios, one key set of CDR technologies is bioenergy carbon capure and storage (BECCS). READ MORE

  5. 4. Potential of waste-derived VFAs-bearing effluents as an external carbon source for MBBR denitrification of domestic wastewater

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Seyed Reza Manafi Khosroshahi; [2022]
    Keywords : Volatile fatty acids; Denitrification; Wastewater treatment; Biological nutrient removal; Nitrate removal; Electron accepter; Carbon source; Electron doner; Moving bed biofilm reactor; Nanofiltration; VFA concentration; Discharge standards; Carriers; acclimatization; VFAs; MMBR; NF; WWTP; BNR;

    Abstract : In conventional wastewater treatment plants, methanol, ethanol, and acetate are used as carbon source for the denitrification process in the biological nutrient removal. However, growing concern regarding economical costs and carbon footprints from the fossil-based production of these chemicals have forced the companies to look for other alternatives. READ MORE

  6. 5. Modelling gross primary production in semi-arid regions: effects on carbon uptake of intensive agriculture in southern Kenya

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Malin Ahlbäck; [2020]
    Keywords : Physical Geography; Ecosystem Analysis; GPP; Africa; Kenya; Land cover changes; Cropland; Remote sensing; Sentinel-2; Earth and Environmental Sciences;

    Abstract : Background and aim: Gross primary production (GPP) is the largest global carbon (C) flux and an important component for counteracting anthropogenic CO2 emissions, understanding vegetation dynamics, and sustaining universal human standards. Africa plays a prominent role in the global C cycle, though our understanding of GPP dynamics is largely hampered by a paucity of ground-based observations. READ MORE
