    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hari Hara Sudhan Thangavelu; [2022]
    Nyckelord :pillared graphene; porous structure; energy storage; interlayer galleries.; pelargrafen; porös struktur; energilagring; mellanskiktsgallerier.;

    Sammanfattning : Unique layered structure with excellent electrical, mechanical, thermal, and optical properties gives graphene widespread application. Graphene based materials are extensively studied in the field of energy storage such as batteries, hydrogen storage and supercapacitors (SC’s). LÄS MER

  3. 7. Short-term planning and operational profitability of multi-ESS hybrid wind farms

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Javier Ortega Paredes; [2022]
    Nyckelord :Energy storage systems; day-ahead market; wind power; stochastic short-term planning problem; hybrid wind farm; Energilagringssystem; day-ahead-marknad; vindkraft; stokastiskt kortsiktigt planeringsproblem; hybridvindkraftverk.;

    Sammanfattning : The unpredictability and variability of wind power generation can pose an economical risk to the wind power producer when participating in the day-ahead market and delivering the committed generation. These risks come from the creation of imbalances due to a mismatch between the sold and real generation fed to the grid. LÄS MER

  4. 8. Alternative Energy Storage Solutions and Future Scenarios of the Austerland Energy System

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

    Författare :Jennie Lindblom; [2022]
    Nyckelord :Gotland; Östergarnslandet; Polygeneration system; Homer Pro; Solar PV; Wind power; Energy storage; Battery; Hydrogen; Flywheel; Redox Flow battery; Pumped Hydro; Sustainable development.; Gotland; Östergarnslandet; Poly-genererings system; Homer Pro; Solceller; Vindkraft; Energilagring; Batterier; Vätgas; Svänghjul; Redox Flödesbatteri; Pumpkraftverket; Hållbar utveckling.;

    Sammanfattning : The project Austerland Energi at the eastern tip of the island of Gotland called Östergarnslandet was started as a response to the larger project Omställning Gotland funded by the Swedish government as an effort for a pilot project to convert to renewable energy to reach zero CO2-emissions for the country in 2045. The current plan for the Austerland energy system is a solar PV and wind production base with energy storage in the form of batteries and hydrogen which also can be used as vehicle fuel. LÄS MER

  5. 9. Synthesis of Graphene - Carbon Nanotube Hybrid Structures

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Aniruddha Paul; [2021]
    Nyckelord :Graphene; Carbon nanotubes; Graphene-CNT hybrid structures; Chemical Vapor Deposition CVD ; Grafen; Kolnanorör; Grafen-CNT-hybridstrukturer; Kemisk ångdeposition CVD ;

    Sammanfattning : Graphene and Carbon nanotubes (CNTs) have been researched for more than a decade due to their extraordinary properties and advantages towards applications like electronics, structural re-enforcements, thermal management and energy storage. Graphene-CNT hybrid structures have been predicted to further enhance the exceptional properties and overcome some of the shortcomings of the individual materials. LÄS MER
