Alstom and American Electric Power sign agreement to bring
CO2 capture technology to commercial scale by 2011

The project will be implemented in two phases. In phase one,
Alstom and AEP will jointly develop a 30 MWth product
validation plant that will capture CO2 from flue gas emitted
from AEPs 1300 MW Mountaineer Plant located in New
Haven, West Virginia. It is targeted to capture up to 100,000
tonnes of carbon dioxide (CO2) per year. The captured CO2 
will be designated for geological storage in deep saline
aquifers at the site. This pilot is scheduled for start-up at
the end of 2008 and will operate for approximately 12-18
months.

In phase two, Alstom will design, construct and commission a
commercial scale of up to 200 MW CO2  capture system on
one of the 450 MW coal-fired units at its Northeastern Station
in Oologah, Oklahoma. The system is scheduled for start-up in
late 2011. It is expected to capture about 1.5 million tonnes
of CO2  a year, commercially validating this promising
technology. The CO2 captured at Northeastern Station will be
used for enhanced oil recovery.

Alstoms post-combustion process uses chilled ammonia
to capture CO2. This process dramatically reduces the energy
required to capture carbon dioxide and isolates it in a highly
concentrated, high-pressure form. In laboratory testing
sponsored by EPRI and others, Alstoms process has
demonstrated the potential to capture over 90% of CO2 at a cost
that is far less expensive than other carbon capture
technologies. The isolated CO2, once captured, can be used
commercially or stored in suitable underground geological
sites.

Philippe Joubert, President of Alstom Power Systems, said:
We are extremely proud that AEP has chosen
Alstoms clean coal technology for this major
project.  Our partnership with AEP will result in the
worlds first  clean coal power plant and will be
applicable not only for new plants but also for existing power
plants.
