1. Modeling and Evaluation of High Temperature PEM Fuel Cells for Truck Applications
Master-uppsats, Linköpings universitet/Institutionen för systemteknikSammanfattning : With increasing demands on lowering carbon emissions, fuel cell hybrid electric vehicles (FCHEV) have been seen as an alternative to the fossil-fuel driven trucks of today. These would have less emissions and strive to have the same range as any diesel driven transport vehicle. LÄS MER
2. Alternative Drivetrain for Future Freight Trucks
Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknikSammanfattning : Presently, heavy-duty trucks are responsible for approximately 25% of global CO2 emissions. Although the world seems to incline towards the transport sector's electrification, the electrification of long-range freight trucks is profoundly challenging. LÄS MER
3. Sustainable transportation and mapping of logistics activities - With the goal of having fossil-free transportation by 2030
Master-uppsats, Lunds universitet/Teknisk logistik; Lunds universitet/Institutionen för teknisk ekonomi och logistikSammanfattning : Today’s supply chains have become more global than ever before, which has brought out an enormous increase in environmental damage such as CO2 emissions. In an initiative to become more environmentally friendly, Swedish Food Federation has launched a joint sustainability manifest. LÄS MER
4. Numerical Optimal Control of Hybrid Electric Trucks : Exhaust Temperature, NOx Emission and Fuel Consumption
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : The controls for a parallel hybrid electric truck are optimized using numerical optimal control. Trade-offs between catalyst light-off times, NOx emission and fuel consumption have been investigated for cold starts at two operating points, as well as temperature differences between conventional and hybrid powertrains during WHTC (World Harmonized Transient Cycle).
