  1. 1. Det fossilfria stålets framtidsutsikter och förmåga att nå globala klimatmål

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggproduktion

    Författare :Louise Johansson; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Den globala uppvärmningen är ett faktum. Stål är ett material som används i stor utsträckning och kan på grund av dess egenskaper inte alltid bytas ut mot alternativa material. Problemet är att stålindustrin står för en betydande del av Sveriges koldioxidutsläpp. LÄS MER

  3. 2. Assessing Electricity Prices and Their Driving Mechanisms in Brazil with Neural Networks

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

    Författare :Henrique Costabile; [2023]
    Nyckelord :;

    Sammanfattning : In general, electricity prices are very volatile and derive from many external variables. In Brazil, this price is determined by computer models developed and operated by government organizations. The supply and demand relationships are not enough to determine prices in Brazilian submarkets. LÄS MER

  4. 3. Investigation of acidic chemical recycling of poly(acetal-ester)s

    Magister-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Saga Vesterbacka; [2023]
    Nyckelord :Poly actetal-ester s; Chemical plastic recycling; Hydrolysis; Acidic degradation; Akestra; PHVT; Re-polymerization; Polymer technology; Chemistry;

    Sammanfattning : Plastic recycling is a very relevant topic from both environmental and economic viewpoints. Chemical plastic recycling is a logical solution to the plastic problems, which shows the potential to reduce plastic waste and carbon emissions from burning the plastics. LÄS MER

  5. 4. Techno-economic analysis of large-scale production of e-methanol, via CO2- hydrogenation, in Power-to-X

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Jonathan Ahlbäck Ikonen; [2023]
    Nyckelord :Power-to-X; E-methanol; Hydrogen Production; CO2-hydrogenation; Methanol Synthesis; Decarbonisation; Chemical Engineering; Technology and Engineering;

    Sammanfattning : Global levels of carbon emissions are constantly rising causing irreversible damages to ecosystems. The heavy transport sector and the industrial sector are responsible for large amounts of the emissions on a yearly basis. LÄS MER

  7. 5. Batteries charging into the future? Techno-economical analysis of BESS participation on the Swedish frequency regulation market using a mixed method approach

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Theodor Rosengren; [2023]
    Nyckelord :Battery Energy Storage Systems; Frequency Regulation; FCR-D; FFR; economic feasibility; Sweden; Technology and Engineering;

    Sammanfattning : As the penetration of variable renewable energy is increasing, the demand for flexibility in the electrical grid is on the rise. One way in which flexibility is needed is to provide frequency regulation. If electricity consumption and production momentarily are unbalanced there needs to. LÄS MER
