how is natural gas utilsed in this process ??

Excuse my ignorance, but would someone like to explain how the natural gas is used in the "bluegen" to create the electricity ? And if the natural gas is not burnt, well what happens to it, and how much greenhouse gas is emitted during and after the process is completed ?? If the gas is not used as a combustible material, is all the gas used, and is it non combustible after the process, and also what remains of the gas, and in what form, ??

As an aside, what a great anne, possibly the best anne i.ve read from this company, GLTAH from hereonin :))
