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

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

   Författare :Ebba Söderström; Emanuel Bengtsson; [2022]
   Nyckelord :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;

   Sammanfattning : 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.

   Sammanfattning : 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. LÄS MER

5. 4. Power-to-Gas and zero-emission buses in Uppsala : challenges and Opportunities from a techno-economic perspective

   Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Energy and Technology

   Författare :Mårten Rosell; [2021]
   Nyckelord :Power-to-gas; bränsleceller; medicinsk syrgas; modellering; lönsamhet;

   Sammanfattning : This thesis has explored the use of power-to-gas technology as a means to produce hydrogen for fuel cell electric buses. The municipal council of Uppsala are looking at options to electrify the local city and regional bus fleet but have been faced with power capacity constraints on the local electrical grid. LÄS MER

7. 5. The Swedish energy system and the role of hydrogen : a modelling study of the energy and transport sector

   Master-uppsats, KTH/Energi och klimatstudier, ECS

   Författare :Adrian Lefvert; [2018]
   Nyckelord :;

   Sammanfattning : In light of the ongoing climate change dilemma, and the consequences that a failure to reduce the greenhouse gas emissions to a stable level will most likely induce, there is an overwhelming consensus among scientists and political leaders that actions are necessary to ensure that adaptation and mitigation options are secured. The European Union, as well as the Swedish government, agrees with the Intergovernmental Panel on Climate Change and the United Nations Conference of Parties that a reduction of the fossil fuel dependency is essential.
