Methods and systems for conversion of a carbon containing fuel to CO2 and H2O. An air stream is fed to a first ion transport membrane unit obtaining a pure oxygen stream from a permeate side and an air stream with a reduced oxygen content from a retentate side. The air stream with a reduced oxygen content is fed to a second ion transport membrane unit and a gaseous first carbon containing fuel is fed to a permeate side of the second ion transport membrane. The first carbon containing fuel is reacted with oxygen transported through the second ion transport membrane forming an at least partially combusted first fuel. The at least partially combusted first fuel, at least a part of the pure oxygen stream and optionally a second carbon containing fuel is fed to a combustion chamber for combustion. An exhaust stream comprising essentially CO2 and H2O is obtained.
