  1. 16. Techno-economic study of second-life EV batteries as alternative energy storage and comparison with lead-acid and new Li-ion batteries in off-grid PV systems

    Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Vijay Arumugam; [2022]
    Nyckelord :Second-life EV batteries; PV off-grid systems; HOMER; comparison of batteries in off-grid systems; repurpose the retired EV batteries.;

    Sammanfattning : The global EV stock is expected to increase from 7.2 million in 2019 to nearly 140 million vehicles by 2030. So, the demand for the battery also increases due to the increase in the number of EVs. LÄS MER

  3. 17. Solceller på Västergårdsgymnasiet : En förstudie för att implementera solceller och energilagring ur ett ekonomiskt perspektiv

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Tim Gyulanszky; [2022]
    Nyckelord :solceller; energilagring; vätgas; litium-jon; flödesbatteri;

    Sammanfattning : The purpose of the project was to carry out a study of a potential solar cell facility at Västergårdsgymnasiet. Previous studies have established that there is the greatest potential for electricity production during the summer period, which coincides with the load at its lowest. LÄS MER

  4. 18. Feasibility Investigation of Floating PV in Hydro reservoirs : A case study on tropical and mediterranean climatic regions

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Adithi Prasannalal Sheena; [2021]
    Nyckelord :Floating PV; HOMER Pro; tropical; mediterranean;

    Sammanfattning : To secure the growing energy demand due to the rise in population and technological advancements, countries worldwide are looking for alternatives or complementary generation sources to support the existing grid infrastructure and power generating system. The increase in global temperature and climate change forces each country to switch to clean energy production. LÄS MER

  5. 19. 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.

  7. 20. Design of a Polygeneration system in Filipinas ETCR, Colombia

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

    Författare :Germán Ropero Pérez; [2021]
    Nyckelord :;

    Sammanfattning : This project has addressed the design of a cost-effective Polygeneration system that guarantees a continuous, equitable and environmentally friendly energy supply for the rural settlement of Filipinas ETCR, (in Spanish, Espacios Territoriales de Capacitación y Reincorporación) Colombia, which is currently not achieved, due to a system that relies on the national electricity grid (with numerous outages) and on LPG (Liquefied Petroleum Gas) and wood to meet the thermal demand, mainly for cooking. For this purpose, in addition to the current energy supply situation, the energy demand according to type (electricity and heat) and sector (residential, commercial and agro-livestock) is characterized.
