1. 1. Cost and financing of the sustainability transition of the Swedish road freight transport sector

   Författare :Elmira Parviziomran; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Godstransporter; Hållbar utveckling; Fossila bränslen; Fordon; Kostnader; Finansiering; Batterier; Sustainable development; Electric batteries; Vehicles; Freight and freightage; Fossil fuels; Sustainability transition; Decarbonization; Heavy-duty vehicles; Cost; Financing; Battery; Circular economy; Diesel fuels;

   Sammanfattning : The cost and financing of the road freight sector’s sustainability transition, driven by significant greenhouse gas (GHG) emissions and cost considerations, represent an urgent yet underexplored research focus. This study investigates the costs of fleet replacement with zero-emission powertrains, battery electric vehicles (BEVs) and fuel cell vehicles (FCVs), emphasizing cost variables that have been overlooked in transition research.

3. 2. Policy Analysis for Different Types of Decision-Making Situations

   Författare :Matts Andersson; Svante Mandell; Karin Brundell-Freij; Jonas Eliasson; Lars Hultkrantz; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; transaction cost; transition cost; misalignment; parking policy; strategic interaction; spillover; resource flow; reference forecast; kilometer tax; minimum parking requirements; Transportvetenskap; Transport Science;

   Sammanfattning : This thesis seeks to contribute to decision support for policy makers in the transport sector. In order to frame the papers and to relate them to the broad field of “policy analysis”, I have structured the papers around a simple framework with three decision levels: responsibility, policy gap, and policy measure.

4. 3. Modeling Photofunctional Transition Metal Complexes

   Författare :Iria Bolano Losada; NanoLund: Centre for Nanoscience; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; density functional theory; earth-abundant; molecular dynamics; quantum chemistry; photosensitizer; photophysics; photochemistry; solar fuels; solar energy conversion; transition metal complexes;

   Sammanfattning : Transition metal complexes play a crucial role in solar energy conversion. These coordination compounds have promising applications in dye-sensitized solar cells and photocatalysis, with particular interest in solar fuel production. LÄS MER

5. 4. Hydrogen in the European energy system - The cost dynamics and the value of time-shifting electricity generation

   Författare :Simon Öberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost; energy systems modeling; Hydrogen; gas turbine; system dynamics; time-shifting;

   Sammanfattning : If the European Union is to become climate-neutral by Year 2050, as envisioned in the European Green Deal, the European energy system must undergo an unprecedented transformation towards eliminating its carbon emissions. For this transition, renewable electricity plays a central role, not only in replacing the current fossil-based electricity generation, but also in promoting the electrification of other sectors, such as transport and industry, sectors which are currently based on fossil fuels.

7. 5. Energy transition in transportation : Applying TIMES-based energy system optimisation models to sub-national levels

   Författare :Jonas Forsberg; Anna Krook-Riekkola; Andrea Toffolo; Åsa Lindman; Krister Sandberg; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system analysis; ESOM; Transportation; Climate change; Air quality; Energy Engineering; Energiteknik;

   Sammanfattning : Transportation is embedded in the fabric of society and a key enabler of socio-economic development, but it is also a major source of carbon dioxide (CO2) and local air pollution (AP). Cities collectively account for around three quarters of total energy-related CO2 emissions, and the negative health impacts from local APs are most felt in dense urban environments. LÄS MER
