1. 16. Calibration of the Measurement System for Methane Pyrolysis in Rocket Nozzle Cooling Channels

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

   Author : Jennifer Ly; [2023]
   Keywords : Correlational method; gas analysis; real time measurements; speed of sound; thermal conductivity; methane pyrolysis; rocket nozzle cooling; Korrelationsmetod; gasanalys; mätningar i real tid; ljudhastighet; värmeledningsförmåga; metanpyrolys; kylning av raketmunstycken iv;

   Abstract : Methane-based rocket propellant is gaining traction as a green technology with advantages in sustainability, cost-effectiveness, and performance. However, under high temperatures found in rocket nozzle cooling channels, methane can undergo thermal decomposition known as methane pyrolysis, resulting in the generation of hydrogen and solid carbon.

3. 17. Harnessing Hydrogen and Batteries: Hybrid Energy Storage System for Versatile and Profitable Renewable Power Production

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Nora Jaredson Lilja; Hugo Björling; [2023]
   Keywords : Energy storage; Hydrogen energy storage; Battery storage; Hybrid storage; Wind power; Solar power; Combined wind and solar power production; Variable renewable energy sources; Power management; Energy storage operational strategy; Plannable renewable power production; Technology and Engineering;

   Abstract : This thesis explores the integration of hydrogen and battery energy storage systems as a means to enhance the management of wind and solar power in the pursuit of a greener grid. The objective of the study is to identify the potential benefits and challenges associated with hybrid energy storage systems (HESS) and their role in renewable energy integration. READ MORE

4. 18. A process to assess fossil-free transport transition pathways and develop a sustainability roadmap for transport purchasers

   University essay from Lunds universitet/Internationella miljöinstitutet

   Author : Lauren Brach; [2023]
   Keywords : Roadmap; corporate carbon strategy; decarbonisation; transportation; fossil-free; Earth and Environmental Sciences;

   Abstract : Most (93%) of the greenhouse gas emissions in the transport sector come from road traffic in Sweden which includes passenger and freight transport activity (Trafikverket, 2022). The aim of this thesis was to understand pathways that transport purchasers can pursue to reach the fossil-free transportation goals from manufacturing plant to customer and to develop a process for assessing a market and developing a roadmap for achieving fossil-free transportation.

5. 19. Deep Neural Networks as SurrogateModels for Fuel Performance Codes

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Wenhan Zhou; [2023]
   Keywords : Transuranus; AI; Nuclear Fuel Rods;

   Abstract : The core component of a nuclear power plant is the reactor and the fuel rods that supply it with fission fuel. Efficient and safe energy extraction is thus highly dependent on the reactor design and the conditions of the fuel rods. To anticipate high-quality operation and potential risks in advance, one must perform simulations on the fuel rods. READ MORE

6. 20. Green hydrogen from offshore wind in southern Sweden : Case study on 500MW offshore wind farm

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Axel Olsson; [2023]
   Keywords : Electrolysis; Hydrogen; Offshore; Wind; Optimisation; Electrolys; Vätgas; Vindkraft; Optimering;

   Abstract : Variable renewable energy and green hydrogen demand is expected to increase within the European union in attempts to mitigate climate change. A high penetration of variable renewable energy can result in volatile power prices affecting the profitability of such actors. READ MORE
