  1. 36. Feasibility Study of Available Hydrogen Production Techniques in Sweden using Single-Issue LCA Carbon Footprint

    University essay from KTH/Industriell bioteknologi

    Author : Beatrice Westén; [2022]
    Keywords : Hydrogen; biohydrogen; LCA; Single-Issue LCA; streamlined LCA; Life Cycle Assessment; Carbon Footprint; CF; Environmental System Analysis; Sweden; holistic; future scenarios; Vätgas; biovätgas; LCA; Single-Issue LCA; streamlined LCA; Life Cycle Assessment; Carbon Footprint; CF; Environmental System Analysis; Sverige; holistisk; framtida scenarios;

    Abstract : Sverige har som mål att bli helt fossilfri till år 2045. Energymyndigheten har därför tagit fram ett förslag till Vätgasstrategi för att ställa om vätgasproduktionen till att vara helt fossilfri till 2045. Idag används ca 180 000 ton vätgas, vilket motsvarar ett energiinnehåll på ca 6 TWh. READ MORE

    Abstract : Trafikverket operates about 12000 Switches and crossings (SnCs) of which 6800 are equipped with an electrical heating system of 10−30kW power to keep SnCs functional throughout the winters by keeping them free of Snow/Ice. The energy consumption is approximately 200−130GWh/year costing approximately 10−15 million Euros annually. READ MORE

  6. 40. Non-Intrusive Load Monitoring to Assess Retrofitting Work

    University essay from KTH/Matematisk statistik

    Author : Julien Zucchet; [2022]
    Keywords : NILM; retrofitting work assessment; hierarchical Bayesian mixture model; NILM; hierarkisk Bayesiansk blandningsmodell; utvärdering av renoveringsarbetens effektivitet;

    Abstract : Non-intrusive load monitoring (NILM) refers to a set of statistical methods for inferring information about a household from its electricity load curve, without adding any additional sensor. The aim of this master thesis is to adapt NILM techniques for the assessment of the efficiency of retrofitting work to provide a first version of a retrofitting assessment tool. READ MORE
