1. 11. Delivering sustainable energy transition : A techno-economic analysis on households, businesses and communities of the Keweenaw Peninsula

   Master-uppsats, KTH/Energiteknik

   Författare :Francesca Longobardi; Filippo Padovani; [2020]
   Nyckelord :;

   Sammanfattning : Energy security understood as the practice by which risks associated with interruptions to the energy supply are low, represents one of the main objectives of energy policies in many countries. In this context, Keweenaw County or Michigan's northernmost County is placed as locked in an unreliable, unsustainable and particularly wasteful energy system. LÄS MER

3. 12. Evaluation of decentralized ventilation system with heat recovery

   M1-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Författare :Sunkavalli Kowshik Chowdary; [2020]

   Sammanfattning : Cities and districts contribute to a large fraction of the total energy consumption in Sweden. The residential- and service sector accounted for almost 40% of the total energy consumption in 2018. The increasing urbanization also puts more importance on the energy supply, distribution and consumption in these areas. LÄS MER

5. 14. Feasibility Study of Chemical Energy Storage for an Energy Efficient Commercial Office Space

   Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

   Författare :Kerry-Leigh Maritz; [2019]
   Nyckelord :“Chemical Energy Storage”; “Commercial”; “Energy Storage”; “Load Demand Shift”; “50kW Solar System”;

   Sammanfattning : Shifting the load demand of a commercial office space to utilise off peak tariffs would lead to cost savings as power is cheaper at this time. To achieve this shift, chemical energy storage was considered using Lead Acid batteries, Lithium-ion batteries and Advance Lead Acid batteries. The output of these storage types is electricity.
