1. 1. Hydrogen Pipeline Infrastructure Design for Germany in 2045

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

   Författare :Flora Marianne von Mikulicz-Radecki; [2023]
   Nyckelord :Hydrogen Transport Infrastructure; Pipeline Networks; Retrofitting; Infrastructure Planning; Peak Hour Hydrogen Demand; Utilization Rate; Costs of Avoided Emissions; Carbon Neutrality; Infrastruktur för vätgastransport; rörledningsnät; eftermontering; infrastrukturplanering; efterfrågan på vätgas under m;

   Sammanfattning : Germany’s commitment to carbon neutrality by 2045 underscores the need for climate action, with hydrogen’s multiple uses in industry, transport, and energy offering a viable solution. Efficient retrofitting of the extensive natural gas pipeline network can enable hydrogen to be transported from supply to demand centers. LÄS MER

3. 2. Route Planning of Battery Electric Heavy-Duty Commercial Vehicles : Using Contraction Hierarchies and Mixed Integer Programming

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Datalogi

   Författare :Olle Delborg; Elias Insulander; [2023]
   Nyckelord :route planning; route optimization; contraction hierarchies; mixed integer programming; vehicle routing problem; electric trucks; electric vehicles; battery; openstreetmap; shortest path; Dijkstra;

   Sammanfattning : This thesis addresses route planning of Battery Electric Heavy-Duty Commercial Vehicles to enhance the reliability of electric vehicle transport. Collaborating with Scania, a Swedish truck manufacturing company, the goal is to develop a pipeline that uses open source data from OpenStreetMap and performs a modified Contraction Hierarchy in order to create a graph that can be used as input to a modified Vehicle Routing Problem formulation using Mixed Integer Programming.

4. 3. A case study of disjunctive programming: Determining optimal motion trajectories for a vehicle by mixed-integer optimization

   Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

   Författare :Oskar Jagstedt; Elias Vitell; [2023]
   Nyckelord :Optimization; disjunctive programming; integer programming; Gurobi; big-M; nonlinear programming;

   Sammanfattning : This report considers an application of mixed-integer disjunctive programming (MIDP)where a theoretical robot can jump from one point to another and where the number ofjumps is to be minimized. The robot is only able to jump to the north, south, east andwest. LÄS MER

5. 4. Assessment of hydrogen supply chain for transport sector of Sweden

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