  1. 6. There is a New Road in Town

    University essay from Lunds universitet/Produktionsekonomi

    Author : Anton Lindström; Oscar Jakobsson; [2021]
    Keywords : Iterative research; Electric Road Systems; ERS; Electrification; Commercialization; Stakeholder analysis; Case study; Investment Decision; Investment modelling; Business and Economics;

    Abstract : This master thesis explores commercialization of electric road systems in urban environments, using a combined methods approach, in contrast to previous studies that have focused on long haul transportation. First, through interviews and document gathering, a stakeholder map was constructed, and the incentives of the identified stakeholders were analyzed. READ MORE

  3. 7. Predictive Energy Management of Long-Haul Hybrid Trucks : Using Quadratic Programming and Branch-and-Bound

    University essay from Linköpings universitet/Fordonssystem

    Author : Erik Jonsson Holm; [2021]
    Keywords : Predictive energy management; quadratic programming; branch-and-bound; mixed-integer quadratic programming; energy optimization; look-ahead control; model predictive control; receding horizon control; optimal control; convex optimization; heavy-duty vehicle; long-haul truck; hybrid electric vehicle;

    Abstract : This thesis presents a predictive energy management controller for long-haul hybrid trucks. In a receding horizon control framework, the vehicle speed reference, battery energy reference, and engine on/off decision are optimized over a prediction horizon. READ MORE

  4. 8. Greenhouse Gas Emissions Reduction in the Heavy-Duty Transport Sector - A Case Study of Renewable Energy Carriers in Sweden

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Karolina André; William Degerstedt; [2021]
    Keywords : Battery electric vehicle; Biofuels; Greenhouse gas; Heavy-duty vehicles; LCA; Renewable energy carriers; Renewable fuels; TCO; Transport sector; Well-to-wheel; Technology and Engineering;

    Abstract : Den svenska transportsektorn står för ungefär en tredjedel av landets totala utsläpp av växthusgaser och släppte 2019 ut 16,4 Mt CO2-ekvivalenter. Av dessa står den tunga vägtrafiken för cirka 20 % och är efter passagerarfordonen den största källan till utsläpp av växthusgaser inom sektorn. READ MORE

  5. 9. Green hydrogen production at Igelsta CHP plant : A techno-economic assessment conducted at Söderenergi AB

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

    Abstract : The energy transition taking place in various parts of the world will have many effects on the current energy systems as an increasing amount of intermittent power supply gets installed every year. In Sweden, just as many other countries, this will cause both challenges and opportunities for today´s energy producers. READ MORE

  6. 10. Machine Learning Enabled Nonlinear Phase Noise Mitigation for Coherent Optical Systems

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Sergio Steven Gutierrez; [2020]
    Keywords : QAM; NLIN; NLPN; Machine Learning; Coherent Optical Communication; Nonlinear Noise Compensation; Physics and Astronomy; Technology and Engineering;

    Abstract : In the current development of coherent optical communication systems, nonlinear noise is considered to be the ultimate bottleneck when extending the transmission length. In this report we suggest a nonparamter digital signal processing scheme to extend the transmission length of a fiber link. READ MORE
