Abstract: In order to gain a more mature share in the future energy supply, green gas supply chains\nface some interesting challenges. In this thesis green gas supply chains, based on codigestion\nof cow manure and maize, are considered. The produced biogas is upgraded to\nnatural gas quality and injected into the existing distribution gas grid and thus replacing\nnatural gas. Literature research showed that relatively much attention has been paid up to\nnow to elements of such supply chains. Research into digestion technology, agricultural\naspects of (energy) crops and logistics of biomass are examples of this. This knowledge is\nindispensable, but how this knowledge should be combined to help understand how\nfuture green gas systems may look like, remains a white spot in the current knowledge.\nThis thesis is an effort to fill this gap. A practical but sound way of modeling green gas\nsupply chains was developed, taking costs and sustainability criteria into account. The way\nsuch supply chains can deal with season dependent gas demand was also investigated.\nThis research was further expanded into a geographical model to simulate several degrees\nof natural gas replacement by green gas. Finally, ways to optimize green gas supply chains\nin terms of energy efficiency and greenhouse gas reduction were explored.
