Alstom and Dow Collaborate to Combat Climate Change

A New Advanced Amine CO2 Capture Pilot Plant in West Virginia

SOUTH CHARLESTON, W.Va., March 30 /PRNewswire/ -- Alstom, a world leader in
power generation, and The Dow Chemical Company (NYSE: DOW), a global gas
treating industry leader, announce the design and construction 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.

Alstom will design, construct and operate the pilot plant, which is expected
to capture approximately 1,800 tons per year of CO2 from flue gas using
Alstom's and Dow's advanced amine technology. Dow will provide the site and
utilities, as well as the chemicals and its amine technology expertise for
this project. The pilot plant is expected to be operational by 3Q 09.

"We are thrilled to be part of this groundbreaking project in CO2 capture,"
said Janet Giesselman, President and General Manager of Dow Oil & Gas. "This
technology has immense potential--for the local community, industry,
environment and our business. Developing advanced amine technology will
provide sustainable energy solutions now and into the future."

"Coal, which represents over two thirds of the world's power generation, is
and will continue to be an essential part of the world's energy mix," said
Philippe Joubert, Alstom Executive Vice President and President of Alstom
Power. "But only by reducing its CO2 output can coal remain a viable source of
power generation. Our cooperation with Dow further demonstrates our leadership
and commitment in this field, as well as providing the validation we need to
launch our amine-based CO2 capture technology on a commercial scale."

All the coal used in the pilot will be sourced locally in West Virginia. By
constructing a facility capable of capturing CO2, Alstom and Dow will help
assure that coal remains an important and sustainable part of the United
States' energy security.

This project is an important element of Dow's 2015 sustainability goals.
According to Vice President of Sustainability, Neil Hawkins, "Dow is committed
to providing solutions that improve energy efficiency, promote renewable
energy, improve the environmental performance of our existing energy sources,
and enable carbon capture and sequestration. Dow is a leader in bringing these
solutions forward."

In 2008, Dow and Alstom entered into a Joint Development Agreement to develop
advanced amine technology for CO2 capture. Currently, Alstom is working with
Dow to develop a commercial offering of an advanced amine-based scrubbing
technology for industrial sources that produce exhaust or flue gases
containing CO2 and high levels of oxygen. The new process will significantly
reduce the amount of energy required for CO2 separation and capture. The West
Virginia pilot plant will validate this new technology.
