Title: Carbon capture and geological storage for Scotland


1
Carbon capture and geological storagefor Scotland
CCS explained Impact Scotland Ready -
ness Challenges Scotland
Stuart Haszeldine University of
Edinburgh School of GeoSciences
2
Explained
Enables transition, ONLY direct reduction of
CO2, Large impact, Scotland advantage.
-- Partial cleanup, Costs more (than now), Needs
big companies, Requires more fuel.
3
CO2 capture and storage
10,000yr remedy bury CO2 in aquifers or
oilfields
4
North Sea Saline Aquifer CO2
5
Impact and Ready-ness
6
Scottish CO2
EITHER Stop coal and gas use OR Capture CO2
IF .. by 2020, Scotland has 50 electricity
from renewables. How is the other 50 made?
7
Scottish liability
Longannet
New coal
CO2 tonnage
10 Mt/yr coal SP
Cockenzie
8 Mt/yr coal ??
4.1 Mt/yr coal SP
Peterhead
1.5 Mt/yr gas SSE
Replace Refit New
8
UK competition CCS 2008
0.4 GW, soon after 2014
Longannet 10 Mt CO2 /yr coal Scottish Power
BP Alternative Energy Withdrawn
Hunterston 1.6 GW 8 Mt
CO2
Kingsnorth 1.6 GW, 8Mt CO2 E.ON
Scotland MAY be UK leader.
But what is Plan B if it loses?

Sources and options Scottish Region Storage
14 companies Feb 2009
AIMS Sources Timings Routes Stores Costs
3) EOR import UK EU?
2) Aquifer
CapacityUK 20yr or 1,000yr ?
1) Export
10
Europe 12 CCS projects
500 M tons Emission Allowances for new plant
gt 10 x 400 MW coal plant 2013 - 2020 500 g
CO2 /kW hr electricity emissions standard EU
Council of Ministers anti EU-A gt may fund ?
11
Challenges
12
Capture Ready coal
Building new coal supercritical power plant -
with future ability to capture CO2, but NOT
capturing now
Emissions Standard 350g (170g) CO2/kwh Ramps
down Intended future date Simple
administration Risk with operator
Capture-Ready Power plant fitted (800g), No
specified route or storage site No date for
operation Complex detailed designs Risk with
Government (us!)
Risks Illusions of progress
Too much regulatory complexity
13
Capture -ready V deployment
New coal? 32Mt capture ready
Clear CCS mandate gt Deployment
Unclear deployment After 2020
Market 2
Market 1
DECC competition
EU-ETS auctions 3,000 M per year From Jan 2013
Create a second market route to fund Scottish
(UK) CCS projects by EU-ETS
14
EU CO2 emissions map

North Sea transport and store
Mongstad
2020 ?
2014
Karsto
2016 ?
50 of EU CO2 export via Rotterdam ? Largest
storage is in Norwegian and Scottish
offshore How to get a transport network to come
north?

16
Scotland To Do
Action on Capture Ready or Emission Standard
Positioning on EU pipeline network Create CCS
capacity, and fund storage research Enabling
CCS in Scotland gt UK Money EU-ETS, Auction,
ROC, Price CCS Largest single CO2 reduction
Over-promised and
under-delivered
