The document discusses modeling a sustainable gas supply chain to match supply and demand. It considers a green gas supply chain and calculates costs at constant production. It provides an example demand curve from 2009-2010 and shows a range of theoretical demand curves. It analyzes 3 flexibility scenarios over 6 months with different swing factors and compares results with different base demand levels. It concludes that increasing flexibility requires more storage and that locating green gas production near business areas makes sense. Further research into flexible biogas production and a real-life case study is recommended.
