  1. 1. Investigating off-grid systems for a mobile milking facility

    Master-uppsats, SLU/Dept. of Energy and Technology

    Författare :Musadag Mohamed Salah Eldin Elzein; [2021]
    Nyckelord :off-grid systems; renewable energy RE; Solar PV; biofuels; insight maker; HOMER;

    Sammanfattning : This study examined the possible renewable energy sources that can provide the necessary power for a mobile Off-grid Automated Milking System (AMS) at a grazing pasture. This involved choosing the most cost effective, environmental friendly and sustainable mean for a mobile AMS which aims to be operating between months of May to September at a rate of milking 20 cows per day.

  2. 2. Medvetenheten om klimatfrågan bland elever i gymnasieskolan och vuxenutbildningen : En empirisk pilotstudie

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Mattias Andersson; [2021]
    Nyckelord :climate change; environmental education; sustainable development; upper secondary school; adult education; klimatfrågan; klimatförändring; hållbar utveckling; miljöundervisning; gymnasieskolan; vuxenutbildning;

    Sammanfattning : The purpose is to study, in a pilot survey, the consciousness of climate change among pupils in secondary school and in adult education. These are the research questions: - What consciousness of climate change do the pupils have? - What are the differences in respect of climate change consciousness between men and women, pupils in adult education and in upper secondary school and pupils in pre-university programmes and in vocational programmes? ”Climate Change Consciousness” is constructed as a concept consisting of ecological, social and economic dimension as well as the components knowledge, attitudes and behaviour.

  4. 4. Business Case, Design and Simulation of Solar Powered Hydrogen Refuelling Stations

    Master-uppsats, Lunds universitet/Institutionen för Energivetenskaper

    Författare :Axel Nordin Fürdös; [2021]
    Nyckelord :Hydrogen; HRS; Energy Systems; Technology and Engineering;

    Sammanfattning : Abstract The thesis investigates some possible pathways for how solar powered Hydrogen Refuelling Stations (Solar-HRS) can be implemented in a economically viable way. This is done by the use of a custom simulation model in MATLAB/Simulunk to simulate and evaluate the inner workings of the Solar-HRS. LÄS MER
