Climate challenge
IEA 2006 default policy scenario
 By 2030 Global CO2 emissions will be 70% higher than they are today
 We must find ways to curb emissions growth from the developing world

E.ON is committed to reducing its CO2 emissions
E.ON’s specific CO2 emissions
in t/MWh
0.72
- 50 %
 Involves all technologies (with major renewables investment)
 Internal modelling suggests CCS is needed (post 2020) in all
0.49
~ 0.36
scenarios
 If there is no significant nuclear build, CCS becomes a major
part of the portfolio.

Target
2030
 50% reduction of CO2 emissions compared to 1990
baseline
 Reduction of CO2 emissions down to 0.36 t/MWh by
2030

The UK Generation Capacity Problem
 By end 2015 the UK will see ~23 GW of plant closures (LCPD and nuclear life expiry) – 30% of UK capacity. Further nuclear
closures likely 2016-2020
 With no new build, demand may exceed supply in winter peaks ~ 2011
35%
 Purely building CCGTS is not an
option
emission targets
 UK will be>75% gas dependent.
 Must remember new build stations will
last ~40 years

The Case For Carbon Capture and Storage
1
CO2 Reductions
 Reduces fossil fuel plant emissions by 90%
 Applicable to coal based economies such as India and China which
are driving world emissions growth.
2
Security of Energy Supply
 Coal based CCS gives security of energy supply, coal can be stored &
freely traded
 Coal+CCS allows the continued burning of coal in a carbon
constrained world
 Only option for a baseload fossil-fuelled future
3
Affordability
 CCS carries a cost penalty over unabated plant
 Cost competitive form of carbon abatement
 CCS is vital to solve the global trilemma

 Project currently under review due to funding issues
Killingholme, E.ON UK
 Single unit IGCC+CCS, net output estimated at 370 MW
 Pre-FEED study completed Sept 07
 Highly promising net efficiency of circa 36-37%
 90% CO2 capture is achievable
 Ideal storage sites identified in depleted gas fields in SNS
 Development currently suspended due to the UK Government’s decision to fund only
post-combustion CCS
COORIVA
 E.ON is involved in the EU-funded COORIVA FP6 project which is looking at
solutions for the development of an IGCC power plant demo project (CO2 capture,
“State of the art IGCC full scale technology”, H2 turbine, coal gasification and gas
treatment)
