Full-commercial initial scenario	—	17.8
Low (−20%) capture capital cost	5	18.7 (+5)
Low (−15%) pipeline capital cost	9	19.7 (+11)
High ($80 per barrel) oil price	—	20.8 (+17)
Lower (commercial-government) pipeline financing cost	21	22.2 (+25)
Lowest (full-government) pipeline financing cost	34	29.7 (+66)
