1. 36. STUDY OF HYDROGEN PRODUCTION IN SMALL AIRPORT : System selection and sizing

   Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Författare :Mohammed Taha; [2022]
   Nyckelord :Hydrogen; Hydrogen as aircraft fuel; Electrolysis systems; Hydrogen storage;

   Sammanfattning : Shifting from fossil fuels and moving towards sustainable and environmentally friendly fuels is vital to combat global warming. Hydrogen's high energy content and abundance on earth qualify it as one of the primary clean fuels, especially when produced from renewable resources. LÄS MER

3. 37. Comprehensive Study of Meta-heuristic Algorithms for Optimal Sizing of BESS in Multi-energy syste

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

   Författare :Joakim Ginste; [2022]
   Nyckelord :BESS; Energy arbitrage; Firefly algorithm; Genetic algorithm; Peak shaving; BESS; energiarbitrage; Firefly algorithm; Genetic algorithm; spetslastutjämning;

   Sammanfattning : The question of finding the optimal size for battery energy storage systems (BESS) to be used for energy arbitrage and peak shaving has gained more and more interest in recent years. This is due to the increase in variability of electricity prices caused by the increase of renewable but also variable electricity production units in the electricity grid. LÄS MER

4. 38. Construction and Validation of a Lab-scaleBorehole Thermal Energy Storage Model

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

   Författare :Haoyang Dong; [2022]
   Nyckelord :borehole heat exchanger; lab-scale model; experimental construction; experiment test; validation; borrhålsvärmeväxlare; labbmodell; experimentell konstruktion; experimenttest; validering;

   Sammanfattning : Borehole heat exchangers are widely used in heat pumps of residential buildings and industrialsystems. It is known as one of the most energy ecient technologies which provides heatingand cooling by using sustainable geothermal energy. The life time of borehole heat exchangerslasts more than 50 years which is longer than combustion boilers. LÄS MER

5. 39. Are Carnot Batteries an Alternative to Converting Coal Power Plants? : An open-sourced technoeconomic optimization approach for testing a new niche for Carnot Batteries.

   Master-uppsats, KTH/Energiteknik

   Författare :Vartan Jakob Ahrens Kayayan; [2022]
   Nyckelord :;

   Sammanfattning : As Europe transitions away from coal-fired power plants, there is an opportunity to reshape the electrical infrastructure. Many of the current plans are to make a switch to natural gas, another fossil fuel. Refurbishing existing power plants has several advantages. Components can be put to a new purpose. LÄS MER

7. 40. Weight prediction of flight control subsystem

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Joel Lundahl; [2022]
   Nyckelord :Aeronautical engineering; aircraft; fighter jet; flight control system; FCS; weight prediction; early weight prediction; hydraulic system; control surfaces; actuator; subsystem; weight estimation; Flygteknik; flygplan; militärflygplan; stridsflygplan; styrsystem; viktprediktering; tidig viktprediktering; hydraulsystem; styrroder; styraktuatorer; aktuator; delsystem; viktuppskattning; metod;

   Sammanfattning : A common dilemma in aircraft design is the importance of knowing weight characteristics at early design stages, since sizing of many important components is dependent on these. Yet precise weight data cannot be determined until the aircraft and its subsystems have been designed in detail. LÄS MER
