Sammanfattning
This thesis investigates the cost and composition of a Swedish system with large scale implementation of CCS and how the implementation is affected by condition
standards, route-flexible vehicle deployment and volume of CO2 captured.
A mixed integer linear programming model that considers the cost of emitted CO2
and each step in the CCS chain. The CCS chain in the model contains the capture
and liquefaction processes, intermediate storage at sites and transportation hubs,
transportation of captured CO2, and the storage sites. The transportation modes
considered in the model are ships, trains, trucks and pipelines. There are 3 condi tions considered in the model, which are combinations of pressure and temperature
during transportation. This model is applied to a case study where Swedish indus trial plants with more than 100 kt annual CO2 emissions are included. The model
adds flexible deployment of vehicles . The system and how it is affected are investi gated by constructing and comparing scenarios.
The modeling result shows that transportation is a relatively small part of the CCS
cost, but this part can increase if there are limited transportation options. The model
also shows that there are multiple ways to set up the system for similar specific chain
costs when the base case and scenarios are compared. Systems with one condition
are likely better than systems with multiple conditions. That a system with only
pipelines is not viable in Sweden. The only difference between route-flexible and
route-specific vehicles is the system composition. Higher volume of captured CO2
have a small decrease in the specific cost. The preferred transportation mode in
the model is ships with large capacity for long distances and trains for shorter
distances. Trucks are also used for shorter distances due to locations missing the
required infrastructure for trains.
