• Bulk making/breaking for off shore CO2 storage• Intermediate Storage• Combine and link pipeline systems and barging/shipping routes: 4 routes• Provide independent custody transfer metering (for ETS)• Network building block (at rivers and coast lines)

CO2 Transport and Storage systems
• Transport from the Emitters via pipelines or barges;
• Collecting CO2 in storage tanks at the CO2 Hub;
• Loading sea vessels for transport to depleted offshore gas fields.
Liquefaction at the Emitter’s siteor at the CO2 Hub
Connecting Hub
5/13/2011 4
• Locking the sea vessel to a floating turret or loading tower linked with the sub-sea system of the depleted gas field;
• Injecting the CO2 into the porous rocks (depleted gas or oil field or aquifers, at required temp’s and pressures ;
• As an alternative, mooring near a platform for discharging the CO2 into a depleted field via the platform utilities
• Ship is designed to carry both CO2 and LPG

2. Intermediate scheme: two combined flows do allow for an off shore pipe => ship moves into alternative CO2 or LPG service
3. Final mature scheme:multiple sources & sinks, both depleted reservoirs and EOR at production wells

General• Start engineering at the sink• Minimize CO2 composition requirements• Combining multiple emitters in one network is technically feasible. • No metallurgical/corrosion issues found other than water: dry at the
sourceSHE• No items of concern encountered• Low vessel collision risk due to high LCO density
5/13/2011 6
• Low vessel collision risk due to high LCO2 density• On shore pipeline through busy areas: 40 barCompression• Up to 100 bar: bull gear compressor (bull gear), beyond: pump.• Moderate ambient temperatures: no power consumption difference
between compression or compression/liquefaction/pumping.Pipeline• In dense phase in order to minimize costs.

GCCSI LLSC study: lessons learned to date
Liquefaction• Optimum CO2 liquefaction condition: -50 ˚C, 7 bara.• Combining parallel compression and liquefaction in one
machine feasible.Storage• Terminal minimum storage volume: 10,000 m3
5/13/2011 7
• Terminal minimum storage volume: 10,000 m3
• Min. costs/m3: > 2000 m3 shop fabricated spheres• Other considerations may call for horizontal bullets.Legislation
Biggest remaining uncertainties: • CO2 custody transfer: who, when and to whom• Monitoring requirements in the mean time

Rotterdam distance to sinks
Dutch sinks are all within the 400 km range.

Preliminary resultsPreliminary results
Barging/shipping• No CO2 venting/re-liquefaction in transit• Barge max. LOA 135 m → 150 m in the future• Max barge size Ruhrgebiet → R’dam: 7500 tonnes (Ruhrgebiet →
Karlsruhe: 6000 tonnes)• Required ship sizes: 10,000 - 30,000 m3
• Ship min. required off loading temperature: 0 ˚C• => sea water suffices as heat source for LCO2 “vaporization”

• => sea water suffices as heat source for LCO2 “vaporization”Ship off loading• HP pressure CO2 unmanned off loading: technically feasible at
acceptable uptimes in deep and shallow water.• Depleted reservoir’s existing wells require retubing• Ship → sink batch injection technically feasible, multiple wells likely
to be required flow wise.• Tubing: low temperature material of construction.

Costs
• CO2 transportation is to be considered as a regular infra structural project: 20+ year contract durations
• CO2 liquefaction’s energy intensity is relatively low => cost break even distances are
5/13/2011 17
cost break even distances are1. for on shore pipe versus barge: 200 km (and not 1500 km)
2. for off shore pipe versus ship: 150 km (and not 750 km)
• Depending on flow and distance the transportation costs may vary from 20 to 120 €/ton (20 year contract)
• Combining multiple emitters in one system is paramount to make CCS affordable, especially for industrial (smaller) emitters
