1. 1. Investigation of different ventilation profiles to avoid stratification in Nearly Zero Energy Buildings

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Alazne Irene Varela Santana; [2023]
   Keywords : stratification; water model; comfort; mixing; temperature; potential energy; net zero energy building;

   Abstract : This research paper examines possible solutions for the problems that warm air heating is suffering in Nearly Zero Energy Buildings. These NZEBs are passive houses constructed to have high energy efficiency where the quantity of power used is equal to the power created annually, produced locally or in the surroundings by renewable energy sources.

3. 2. The effect of nozzle geometry on bubble formation : Physical modeling by air in a water tank

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Mhd Osman Bernieh; [2023]
   Keywords : Nozzle geometry; bubble formation; water tank model; bubble flow; Munstycksgeometri; bubbelbildning; vattentankmodell; bubbelflöde;

   Abstract : The bubble flow is used for different application in steel production and refining processes. It plays in indispensable role in the ladle refining process such as for homogenization and inclusion removal. Hence, it is important to understand the effect of the nozzle outlet geometry on the bubble formation. READ MORE

4. 3. Flexible Sector Coupling (FSC) of Electrical and Thermal Sectors via Thermal Energy Storage (TES) : A Case Study on Oskarshamn Energi

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Raúl Calvo García; Jose María Marín Arcos; [2023]
   Keywords : Flexible sector coupling FSC ; district heating DH ; thermal energy storage TES ; heat pump HP ; capacity optimization; dispatch optimization; open-access tools; Flexibel sektorkoppling; fjärrvärme; termisk energilagring; värmepump; kapacitetsoptimering; leveransoptimering; verktyg med öppen tillgång;

   Abstract : The integration of distributed energy sources and systems is of high relevance for the transition towards a more sustainable energy system. Taking into consideration the  amount of emissions produced by the heating sector, which account for at least half of the energy demand in buildings, district heating systems have the potential to play a key role in the transition, by enabling the integration of various energy sources and provide flexible energy services to the grid.

5. 4. Green hydrogen production in SE4, a business case for large-scale green hydrogen in SE4

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Petter Håkansson; [2023]
   Keywords : Technology and Engineering;

   Abstract : As the greenhouse gas emissions keep on increasing the need for solutions to help reduce emissions across all sectors has never been greater. The European Union has pointed out green hydrogen as a step in increasing the sustainability of the energy sector in Europe. READ MORE

6. 5. Techno-economic analysis of power‑to‑heat‑to‑power storage for a residential building

   University essay from Högskolan Dalarna/Institutionen för information och teknik

   Author : Alicia López de Ceballos Regife; [2021]
   Keywords : Solar energy; storage; PV installation; Li‑ion; residential sector; latent heat; high temperature; hot water tank; hybrid PV; heat pump; self-consumption; CHP; optimization; Nedler and Mead.;

   Abstract : Despite the share of renewable energies worldwide is increasing, which can help in reducing the CO2 emissions, their unpredictability has become a problem due to the mismatch between generation and demand. Among the different alternatives to solve this problem, energy storage is a very interesting solution. READ MORE
