1. 31. Investigation of PPC in an Optical Engine : With focus on Fuel Distribution and Combustion Characterization

   Författare :Sara Lönn; Förbränningsmotorer; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical engine; PPC; Fuel distribution; Methanol;

   Sammanfattning : The global society is dependent on transportation to function and a big part of these transports are driven by an internal combustion engine. Heavy-duty vehicles utilizes conventional diesel combustion is a combustion concept where the fuel is often ignited during the injection event and while it gives a high combustion efficiency, the combustion mode is also characterized by high emission of NOx and soot.

3. 32. Cooperative Transportation Planning and Cost Allocation

   Författare :Joen Dahlberg; Maud Göthe-Lundgren; Stefan Engevall; Jenny Karlsson; Endre Bjørndal; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : A freight forwarder may consolidate its goods transportations in order to achieve a more efficient operation. When goods transportations are consolidated, they may reduce operational costs, e.g. labor and fuel. LÄS MER

4. 33. Co-Evolution of Technology, Markets and Institutions - the Case of Fuel Cells and Hydrogen Technology in Europe

   Författare :Stian Nygaard; CIRCLE; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Innovation; fuel cells; market development; hydrogen; industrial dynamics; business development; innovation policy; Europe;

   Sammanfattning : The birth, growth and maturity of industries, sectors and technologies have spurred the curiosity of researchers as well as managers and policy makers for a long time. Intriguingly, the emergence of a new industry is a complex process including many different actors and with a high level of uncertainty related to technology, institutions and markets facing the actors involved.

5. 34. 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. 35. Analysis of Deformation of Gas Diffusion Layers and the Impact on Performance of PEM Fuel Cells

   Författare :Jiatang Wang; Värmeöverföring; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PEM fuel cell; compression ratio; assembly pressure; porosity; deformed GDL; electric resistance; transport phenomena; model; performance; analysis; OpenFOAM;

   Sammanfattning : Proton exchange membrane (PEM) fuel cells have been promoted due to significant breakthroughs in various aspects and increasing public interests. The porous features of the gas diffusion layer (GDL) and the necessary assembly processes generate localized pressure forces on the channel/shoulder structure of the bi-polar plates (BPP). LÄS MER
