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

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

   Abstract : 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. READ MORE

   Abstract : Railways provide fast, safe, clean, and cheap transportation service. The cost efficiency inrailway operations can be scrutinized from different perspectives. READ MORE

5. 3. Fracture toughness properties of duplex stainless steels

   Author : Henrik Sieurin; Rolf Sandström; Jan-Olof Nilsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; duplex stainless steel; fracture toughness; austenite reformation; sigma phase; material optimisation; Materials science; Teknisk materialvetenskap;

   Abstract : Good toughness properties in base and weld material enable the use of duplex stainless steels (DSS) in critical applications. DSS offer high strength compared to common austenitic stainless steels. READ MORE

6. 4. Electrification of Road Transportation - Implications for the Electricity System

   Author : Maria Taljegård; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; highway E39; CO2 emissions; electric vehicle; electric road systems; energy system modelling; variable renewable electricity;

   Abstract : It is incumbent upon the transport sector to reduce its CO2 emissions by replacing fossil fuels with low-carbon alternatives. Suggested strategies include electrification of the road transport sector through the use of electric vehicles (EVs) with static charging, electric road systems (ERS), and the use of electricity to produce fuels.

7. 5. Multi-Functional Composite Design Concepts for Rail Vehicle Car Bodies

   Author : David Wennberg; Sebastian Stichel; Per Wennhage; Thilo Bein; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Car body; Composite; Finite element; Lightweight; Multi-discipline; Multi-functional; Optimisation; Rail Vehicles; Sandwich Panels;

   Abstract : Structures and material combinations, tailored for multiple purposes, are within the reach of vehicle manufacturers. Besides reducing the environmental impact of the transportation sector these multi-functional structures can reduce costs, such as development, manufacturing and maintenance, and at the same time offer improved comfort to the passengers.
