The Goal

To show that coal can be used in a responsible manner

– It is possible to create a coal fired power plant with “zero emissions”

– There are commercially available primary technology options in 2020

– The cost for carbon dioxide reduction is lower than 20 €/ton of CO2

– There are even better technologies available after 2020

This will allow us to reduce the carbon emissions with 60 – 80 % until 2035 from our generation portfolio

Parallel R&D Routes Needed

• Development of the three main technologies for the 2020 target• Several large scale pilot and demonstration plants, optimized, with full

process integration

• Supporting R&D to reach lower costs, increase process efficiency and achieve better availability

• R&D for new and emerging technologies for deployment after 2020

• Many routes to examine

• Assessment to prioritize the technologies capable to overtake the leading role from any of the three main candidates.

The Logics of the R&D Portfolio

+Total fuel flexibility, co-combustion, lower cost

Circulating fluidizedbeds

Fuel flexibilityand plant versatility

++No energy losses for separationChemical looping

Post 2020 +Higher efficiency, lower cost, hydrogen adaptive

IGWC Hybrid technologies

+++Fuel utilization > 85 %Lower cost

CHP processesUse of process losses

Present Status – CO2 Storage

• The plant produces CO2of a very high quality

– It can be stored anywhere, or sold as a commercial product

– It is a product, not a waste

• Several storage options are examined at present

– We anticipate to have a storage ready, when considerable amounts of CO2start to be produced

Pilot Plant Budget

• Present total budget is estimated at close to 70 million € for the investment in the plant and 23 million € for operating costs during the test period

• Vattenfall has taken decision to finance the Pilot Plant fully. There is presently no public funding at all

• We have invited partners to join us, utilizing the facility and contribute to the funding. Several have indicated participation.

• We seek partners for the storage option

O2/CO2 combustion is the preferred option at present

At present the most competitive and preferred technology for coal.

It needs development, pilot and demo plants to get design data
