  1. 1. Investigation of carbon capture technologies for Sävenäs waste-to-energy plant

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

    Författare :Jasmine Andersson; [2020]
    Nyckelord :CCS; flue gas treatment; waste incineration; energy balance; emission abatement;

    Sammanfattning : Carbon capture technologies have the potential to decarbonize the emissions to air from the heat and power sector and contribute to the necessary greenhouse gas emission mitigation in order to meet the Paris Agreement requirements. The energy requirement and ability to retrofit carbon capture units are crucial to convert existing power plants into more environmental benign processes to meet the Swedish national goal of greenhouse gas neutrality at 2045.

  2. 2. Field study of the drought’s impact on feeding strategy and biological parameters in early lactation dairy cattle

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Mikaela Würtz; [2019]
    Nyckelord :dairy cattle; drought; energy balance; feeding; metabolism;

    Sammanfattning : The summer of 2018 was unusually warm and dry. For animal production, this resulted in poor pastures, reduced harvests of crops, such as roughage and grains, and increased risk for heat stress in the animals. The drought led to problems as in shortage of animal feed, which made the feeding of dairy cattle difficult. LÄS MER

  3. 3. A market-based instrument for renewable energy : Modelling a dynamic price function for local areas

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Författare :Carl Flygare; [2019]
    Nyckelord :renewable energy; pv; solar cells; solar power; electrical grid; dynamic; economy; policy; tariff; förnyelsebar energi; pv; solceller; solenergi; elnät; dynamik; ekonomi; policy; tariff;

    Sammanfattning : This thesis describes the current situation of the electrical grid on a general level and contemporary support policies for residents who feed renewably produced electricity into the grid within a Swedish context. It shows which issues currently exists and suggests a new way to value overproduced renewable electricity which is not self-consumed. LÄS MER

  4. 4. Context-Based Authentication and Lightweight Group Key Establishment Protocol for IoT Devices

    Master-uppsats, Mittuniversitetet/Institutionen för informationssystem och –teknologi
