  1. 6. Life Cycle Assessment of Electric Road Systems - Climate impact in comparison with battery electric vehicles, biogas vehicles and fuel cell electric vehicles

    University essay from Lunds universitet/Miljö- och energisystem

    Author : Ebba Söderström; Emanuel Bengtsson; [2022]
    Keywords : Electric road systems; Elonroad; life cycle assessment; rail; feed-in station; pick-up; on-board charger; climate impact; global warming potential; articulated lorry; lower medium car; bus; Technology and Engineering;

    Abstract : One third of Sweden's total annual greenhouse gas emissions originate from the transport sector today and great changes are thus needed in order to reach the net zero emission target by 2045. One of the most important measures discussed is an increased electrification of the transport sector and a solution with potential to contribute to this transition is electric road systems (ERS), where vehicles are charged dynamically.

  3. 7. Low-carbon hydrogen production from waste plastics via pyrolysis and in-line catalytic cracking process

    University essay from KTH/Kraft- och värmeteknologi

    Author : Yanghao Jin; [2022]
    Keywords : Pyrolysis; catalytic cracking; plastics recycling; biochar catalyst; hydrogen production; Pyrolys; katalytisk krackning; återvinning av plast; biokol; produktion av väte;

    Abstract : This study develops a novel pyrolysis process combined with in-line catalytic reforming toproduce high purity hydrogen and carbon products from waste plastics. The input resource is waste plastic material in the form of discarded Covid masks. READ MORE

  4. 8. Optimization of Infrastructure Investment for Decarbonization of Public Buses Through Electricity and Hydrogen : The Case Study of Umeå

    University essay from KTH/Energiteknik

    Author : Maria Inês Rocha Jacob; [2022]
    Keywords : Electric buses; fuel cell buses; renewable energy sources; green hydrogen; EV charging stations; hydrogen refuelling stations; Sweden; Elbussar; bränslecellsbussar; förnybara energikällor; grön vätgas; laddningsstationer för elfordon; tankstationer för vätgas; Sverige;

    Abstract : Battery electric vehicles and fuel cell vehicles, i.e. hydrogen vehicles, are promising alternatives to internal combustion engine vehicles to reduce GHG emissions from the transport sector. EV charging and hydrogen refuelling infrastructure is crucial to the deployment of alternative fuels in transport. READ MORE

  5. 9. Measuring the [C II]-to-H I connection in high-redshift absorption-selected galaxies

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Gaurav Senthil Kumar; [2022]

    Abstract : HI neutral gas is the basic building block of galaxies. It dictates the star formation rate and hence the metal enrichment rates within high redshift galaxies. HI neutral gas cannot be directly observed beyond z ≈ 0. READ MORE

  6. 10. A EUROPEAN (NO) COAL AND (GREEN) STEEL COMMUNITY? - A Technological Innovation System case approach in the fossil-free steel sector

    University essay from Göteborgs universitet/Statsvetenskapliga institutionen

    Author : Hannes Wigerfelt; [2021-06-28]
    Keywords : Green steel; HYBRIT; Hydrogen; Technological Innovation System;

    Abstract : The EU has committed to reaching carbon neutrality by 2050 and thereby heavily reducing the emissions of greenhouse gases. Policymakers and scholars have pointed out the development of fossil-free technological energy innovations as crucial in reaching these objectives. READ MORE
