  1. 1. Integration of Heat Recovery from BECCS in a Multi-source Heat and Power Plant : Case Study of Stockholm Exergi

    University essay from KTH/Energiteknik

    Author : Daniel Frisk; [2021]
    Keywords : ;

    Abstract : Rising global temperatures and other extreme weather phenomena have been linked to increasing carbon dioxide (CO2) content in the atmosphere. The damaging impact carbon dioxide (CO2) has on the climate is cumulative. It is essential to reduce the CO2 emissions to hinder further long-lasting negative impacts. READ MORE

  3. 2. New technique for energy efficient CO2-separation through absorption with a sterically hindered amine

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Anton Johansson; [2016]
    Keywords : Experimental Setup; AMP carbamate; NMP; AMP; Absorption; Sterically hindered amine; proof-of-concept; chemical engineering; kemiteknik; Technology and Engineering;

    Abstract : The degree project described in this report also acts as a deliverable for a research project. The research project focuses on a new technique for the upgrading of biogas. This new technology uses a sterically hindered amine to absorb carbon dioxide from the biogas to raise its energy value. READ MORE

  4. 3. A study on the placement of turbines downstream of a hydroelectric power station

    University essay from KTH/Industriell ekologi

    Author : Marie Stjernquist; [2016]
    Keywords : ;

    Abstract : Human energy related activity has increased the carbon dioxide concentration in the atmosphere by 40 % since the preindustrial area. A leading contributor to this is the burning of fossil fuels in order to extract energy. Due to this, we are today facing many issues following climate change and global warming. READ MORE

  5. 4. Energy use and carbon footprint from lawn management : A case study in the Uppsala region of Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Therese Wesström; [2015]
    Keywords : carbon footprint; life cycle assessment; energy; lawn management; klimatavtryck; livscykelanalys; energi; gräs; skötsel;

    Abstract : Atmospheric concentrations of greenhouse gas emissions are now higher than ever before, with severe implications for both humans and ecosystems around the world. To mitigate climate change, large and sustained reductions of greenhouse gas emissions are required. READ MORE

  6. 5. The Jurassic extinction events and its relation to CO2 levels in the atmosphere : a case study on Early Jurassic fossil leaves

    University essay from Lunds universitet/Geologiska institutionen

    Author : Liina Santasalo; [2013]
    Keywords : conifers; Pliensbachian; Australian; Early Jurassic; stomatal proxy; palaeo-CO2; koldioxidhalt; klimat; Australien; tidig Jura; Marburg subgroup; Allocladus helgei; stomata index; CO2; Earth and Environmental Sciences;

    Abstract : The Mesozoic was a so-called “hothouse” time period in Earth’s history, with high concentrations of atmospheric CO2 and elevated temperatures, but the exact climate evolution is not fully known for the entire inter-val. The Early Jurassic for instance is believed to have been a warm period, flanked by two episodes of extremely high CO2, coinciding with environmental degradation and mass extinctions: the Triassic-Jurassic (200 Ma) and the early Toarcian (183 Ma) mass extinction events.
