1. 1. 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

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy prices; CSP; CO2 emissions; hydrogen; CCS; carbon tax; biomass; carbon leakage; liquid biofuels; global energy systems modeling; transportation; passenger vehicles;

   Sammanfattning : This thesis analyzes future fuel and technology choices focusing on transport in a carbon constrained world. The analysis tool used in all five appended papers is the cost-minimizing Global Energy Transition (GET) model. LÄS MER

5. 4. CO2 transportation infrastructure and biomass supply systems for carbon capture and storage - A modeling study of Swedish industry

   Författare :Sebastian Karlsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BECCS; cost optimization; infrastructure; incentives; CCS; biomass supply; industry; CO2 transportation;

   Sammanfattning : Rapid decarbonization of the industrial sector is crucial if the world is to manage to meet the target set in the Paris Agreement of limiting global warming to “well below 2°C”. The main technological pathways for achieving a low-carbon industry are the substitution of fossil feedstocks and energy supply with bio-based alternatives, electrification, and implementing carbon capture and storage (CCS).

7. 5. On Alternative Fuels for Internal Combustion Engines : A study of biodiesel, gaseous methane and methanol

   Författare :Ludvig Adlercreutz; Andreas Cronhjort; Ola Stenlåås; Magnus Sjöberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaseous methane combustion; spark ignition; single cylinder research engine; particle number; particle emissions; oil ash content; CO2; Green House Gases; engine testing; engine development; emissions; combustion chamber design; injector fouling; environmental impact; road transportation; Machine Design; Maskinkonstruktion;

   Sammanfattning :  This thesis covers some of the environmental impacts of internalcombustion engines running on alternative fuels. The focus of thestudies conveyed is the reduction of greenhouse gases and particleemissions, as these two factors are of great importance for the pathsthat road transportation is facing. LÄS MER
