41. Design and Operation of a 10 kWth Chemical-Looping Combustor for Solid Fuels
Sammanfattning : The use of a 10 kWth chemical-looping combustor for solid fuels was investigated. The unit was designed, dimensioned and built and two types of fuel were tested: a South African coal and a petroleum coke from Mexico. Chemical-looping combustion is an alternative to normal combustion for CO2 capture. LÄS MER
42. The role of methane and hydrogen in a fossil-free Swedish transport sector
Sammanfattning : Drastic reductions of greenhouse gas emissions are required to limit the severe risks associated with a changing climate. One measure is to disrupt the fossil-fuel dependency in the transport sector, but it appears difficult and costly in comparison to other measures. LÄS MER
43. Numerical studies of flame stabilization relevant to gas turbine engines using methane and e-fuels
Sammanfattning : The current society undergoes a global energy transformation from fossil fuels to renewable energy. The alternative energy sources to fossil fuels are key factors to accelerate the transition towards a sustainable energy system. Among those, electrofuels (e-fuels) is a promising group that remarkably benefits overall carbon neutrality. LÄS MER
44. Capture of CO2 from solid fuels using Chemical-Looping Combustion and Chemical-Looping Oxygen Uncoupling
Sammanfattning : In order to meet the global demand of CO2 neutral energy, chemical-looping combustion could play an important role. Oxygen can be transferred from the combustion air to the fuel by means of oxygen carrying metal oxide particles circulating between two reactors, an air- and a fuel reactor. LÄS MER
45. ELM: Environmental Assessment of Fuel Supply Systems for Vehicle Fleets
Sammanfattning : This thesis is based on the idea of applying a logistics approach to fuel supply systems. The complete supply chain from energy raw material to end use in the vehicle is analysed while keeping track of energy conversion efficiency, exergy consumption and emissions to air. LÄS MER
