1 CO 2 free Power Plant Project in Vattenfall Relations to the Dynamis project Large CCS Projects meeting Brussels, September 5, 2006 Lars Strömberg Vattenfall AB Group function Strategies Berlin / Stockholm Vattenfall AB

2 The Power Sector The power sector is the major single emitter of CO 2. Vattenfall is one of the major Energy companies in Europe The Power industry must take responsibility and take the lead for introducing CO 2 free technology. To be able to make the deep cuts necessary, CCS is necessary. Primary target is to make technology available in 2020 at an avoidance cost of 20 EUR/ton of CO 2, but also to start development of second generation technology Vattenfall AB 2

11 Electricity generation cost for large power plants in operation by 2020 (ZEP WG1) EUR/MWh Note: Power generation cost without CO2 transport and storage cost No capture Pre-combustion Post-combustion Oxyfuel Hard coal Lignite Natural Gas Vattenfall AB 11

12 Avoidance cost for large power plants in operation by 2020 (ZEP WG1) Note: CO 2 Avoidance cost without transport and storage cost Pre-combustion Post-combustion Oxyfuel EUR/t CO Power plant and CCS technology improvement potential 0 Hard coal Lignite Natural Gas Vattenfall AB 12

13 Cost for hydrogen in a CO 2 free coal co-gen plant Assume the conditions for the economy calculations are as above. The investment is probably too low for a plant with co-generation of hydrogen. The hydrogen contains % non-condensable gases, but is rather clean Accept that the electricity generation cost lies at about 45 /MWh if 7500 hours of operation is assumed. The electricity generation part of the plant has an efficiency of 57 %. This gives a hydrogen cost of about 28 /MWh Hydrogen cost of 30 /MWh might be achievable at site, comparing with natural gas at about /MWh for LNG Lars Strömberg Vattenfall Vattenfall AB AB 13 Corporate Strategies

16 Plant Status The pilot plant will comprise a full chain including boiler, gas cleaning, CO 2 processing and an air separation unit The CO 2 will not be permanently stored initially. It will be released into atmosphere. It will produce liquid CO2 of very high quality (food grade) to a tank storage It is prepared for later connection to a storage project The contracts for the main components are awarded and construction started in june The permitting process is running very smoothly. Permit is expected in October 2006 The estimated cost of the plant itself is 67 mio and a three year test program will have running costs of about 27 mio. All costs covered by Vattenfall and industrialpartners. No public funding. Vattenfall AB 16

22 Conclusions CO 2 Capture and Storage project All three technologies are probably available at a commercial stage in At present the oxyfuel technology is the preferred option due to adaptability to present generation technology and best economy. Only pre combustion capture produces an intermediary product in the form of hydrogen. Other ways of production is by electrolysis, at a significantly higher cost, but already distributed. We do not believe that hydrogen in pure form will be an important energy carrier One 1000 MW power plant, matching the system variation produces enough methanol for about half a million cars.

23 Relation Dynamis and Vatenfall s Pilot plant There are very few synergies to be seen between Vattenfall s Pilot Plant and Dynamis. IGCC with pre combustion capture will be the preferred option if hydrogen is wanted by a market Technology choice is not yet made. Oxyfuel is preferred technology in Vattenfall at present for power production The pilot plant might contribute to the spread of knowledge about CCS and general issues concerning gas processing, permission process and storage Lars Strömberg Vattenfall Vattenfall AB AB 23 Corporate Strategies
