Three-Day World Energy Engineering Congress Goes Pollution-Free with Emissions Credit Donation by FuelCell Energy.

DANBURY, Conn. -- Leonardo Academy Certifies Annual Meeting of the Association of Energy Engineers as 'Cleaner and Greener' by Offsetting Event's Pollution with FuelCell Energy's Emissions Credits

FuelCell Energy, Inc. (NasdaqNM:FCEL), a leading manufacturer of efficient electric power generation plants for commercial and industrial customers, today announced it donated enough emissions credits to offset the environmental impact caused by a three-day global energy conference in Washington, D.C. By contributing more than 2,600 megawatt hours of renewable energy certificates accumulated in operating its ultra-clean Direct FuelCell(R) (DFC(R)) power plants, the company enabled Leonardo Academy to certify the 2006 World Energy Engineering Congress a Cleaner and Greener(SM) program.

Green electricity produced by FuelCell Energy's highly efficient power plants counterbalances the pollution that would be created in generating the same amount of electricity by traditional means to power the show. Donated credits will offset over 5,900 pounds of sulfur dioxide (SO2); 3,800 pounds of nitrogen oxides (NOx); 147 pounds of particulates (PM10 and PM2.5); over 300 tons of carbon dioxide (CO2); and more than 70,000 times the mercury (Hg) pollution to be discharged into the atmosphere from energy related to the conference, including utilities, travel, meals, lodging and other show-connected activities.

"In our conference, we challenge businesses large and small to improve their energy efficiency and enhance the environment," said Albert Thumann, P.E., CEM, Executive Director of the Association of Energy Engineers, sponsors of the WEEC. "FuelCell Energy's emissions credits, and Leonardo Academy's certification, allow us to give back to the community by decreasing our own carbon footprint."

Emissions reduction credits (ERCs) are created through the use of cleaner fuels, highly efficient power generation systems and increased application of renewable energy sources -- thus offsetting pollution created by power generation elsewhere. Some experts predict ERC trading can help foster development of cleaner, more efficient technologies by creating a market for the credits.

ERCs also may be "retired," meaning they no longer may be bought or sold. Removal of such credits from the market in effect reduces the amount of pollution discharged into the atmosphere by halting their ability to be used further as offsets. FuelCell Energy's donated ERCs are being permanently retired.

"We are pleased the Association of Energy Engineers and Leonardo Academy recognize the environmental value of our ultra-clean DFC products," said R. Daniel Brdar, President and CEO of FuelCell Energy. "In making WEEC 'Cleaner and Greener' for the first time, we highlight another way DFC power plants can reduce emissions and participate in emerging RPS markets."
