Abstract
The use of Carbon Capture and Storage (CCS) systems is an important technology to consider for achieving net zero. Optimisation of the supply chain component of a CCS system in terms of layout, time constraints, and central storage has the potential to decrease system cost, increase flexibility, and promote the proliferation of CCS in industry. This work uses a superstructure approach to synthesise an optimal CCS supply chain network which accounts for node locations, time availability, variable production of CO2 and stream quality. Additionally, a carbon hub was introduced to the superstructure, which allowed for temporary storage as well as mixing for incoming streams. Different pathing rules involving the carbon hub were investigated to quantify the benefit of a hub approach. A case study was investigated where it was shown that the inclusion of the carbon hub greatly improved system resilience in the event of constrained storage capacities and reduced the loss of profit by 3 %.
