Alstom and Dow Dedicate New Pilot Plant to Capture CO2

Innovative Chemistry to Play Vital Role in Evolution of CO2 Capture Technology

SOUTH CHARLESTON, W.Va., Sept. 10 /PRNewswire-FirstCall/ -- Alstom (Euronext:
ALO), a world leader in power generation equipment, and The Dow Chemical
Company (NYSE: DOW), a leader in innovative chemistry for the development of
energy and climate change solutions, today celebrated the successful start-up
and operation of a pilot plant to capture carbon dioxide (CO2) from the flue
gas of a coal-fired boiler at the Dow-owned facility in South Charleston, West
Virginia, USA. Governor Joe Manchin III and executives from both Alstom and
Dow were on hand to dedicate the facility.

The pilot plant uses proprietary advanced-amine technology jointly developed
by Alstom and Dow to capture approximately 1,800 metric tons of CO2 per year.
The pilot will operate for the next two years, generating reliable, long-term
data that can be used to optimize this technology for implementation at
coal-fired power plants across the globe. In 2008, the two companies entered
into a Joint Development Agreement to develop this technology. In March 2009,
the companies announced their plans to design and construct the plant.

West Virginia Governor Joe Manchin III said, "This is a good day for West
Virginia. Coal, which represents more than 40 percent of the world's power
generation, is and will continue to be an essential part of the world's energy
mix. But only by reducing its CO2 ( )output can coal remain a viable source
of power generation. As a state rich in fossil fuels, West Virginia, with the
help of Dow and Alstom, is becoming the leader in this revolutionary clean
coal technology."

"As a leader in carbon capture technology, Alstom is excited to take the next
step in commercializing an advanced-amine technology," said Philippe Joubert,
Alstom Executive Vice President and President of Alstom Power. "This pilot
plant is designed to evaluate the technology operating under power plant
conditions, test proprietary innovations jointly developed by Dow and Alstom
and provide data necessary to finalize the design of large-scale demonstration
plants that will apply this technology. Integrating this process with new
advanced coal and gas fired power generation equipment will allow customers to
minimize CO2 emissions while generating electricity as cost effectively as
possible."

"As a world leader in chemistry, Dow is uniquely positioned to help address
the challenges associated with CO2 capture and other energy and climate change
issues," said Heinz Haller, executive vice president of Dow's Performance
Products & Systems portfolio. "We have worked closely with Alstom to develop a
system that will make CO2 capture extremely cost effective and reduce the
amount of CO2 emitted into the atmosphere."
