The political economical drive for the implementation of CCSp

• Green House gas reduction• 20% CO2 reduction in the EU by 2020% 2 y• Coal fired power plants are the biggest CO2 emitters

- coal acounts for 2/5 of the world‘s energy mixcoal acounts for 2/5 of the world s energy mix- CCS for new power plants will be compulsory in the

future- CCS will be retrofitted to

existing power plantsg p p

The political economical drive for the implementation of CCSp

- Initial high costs for development of CCSEU i i t d h+ EU emissions trade scheme

– Currently priced at 24 $/mtonExpected price 50 $/mton by 2020– Expected price 50 $/mton by 2020

- CCS project viable at 45 – 64 $/mton (McKinsey)+ Subsidies of EUR 4 billion by the EU+ Subsidies of EUR 4 billion by the EU

F iblit f i ti i f CO2Feasiblity of existing gas carrier for CO2 Transport

• LNG carrier– Membrane Type

• LPG carriers, Semiref− Type C tanksMembrane Type

– Moss Type– SPB Type

• Ethylene carrier– Type C tanks

Design pressure too low

• LPG carriers, VLGCsType A tanks

May be suitable if the design pressure it above 6.5 barMostly severe filling limit– Type A tanks

Design pressure too low

• Fully pressurized

Mostly severe filling limitrestrictions due to design density or scantling draughty p

carriers– Type C tanks

Only a very limited number ofcarriers would be suitable forCO2

Design temperature too high

ConclusionsCO Li f ti St d Shi iCO2 Liquefaction Storage and Shipping• CCS will be demanded for future power plants

CO S• CO2 Shipping is a viable option to provide the logistics for CCSCO2 t t ith i ti i ld b• CO2 transport with existing carriers would be very limited

• Technical solutions exist for all options of the CO2• Technical solutions exist for all options of the CO2 transport chain by sea

• Combination as Ethylene/LPG/CO2 carrier willCombination as Ethylene/LPG/CO2 carrier will reduce risks for early movers

• TGE provides ship design, and the full cargo handlingTGE provides ship design, and the full cargo handling system including cargo tanks.
