FuelCell Energy Announces Two Billion Kilowatt Hours of Environmentally
Friendly and Efficient Fuel Cell Power Generation

Major Operating Milestone Reached From Growing Installed Base of Ultra-Clean,
Efficient and Reliable Fuel Cell Power Plants

DANBURY, Conn., Dec. 10, 2013 (GLOBE NEWSWIRE) -- FuelCell Energy, Inc.
(Nasdaq:FCEL), a global leader in the design, manufacture, operation and
service of ultra-clean, efficient and reliable fuel cell power plants, today
announced a significant operating milestone with the generation of two billion
kilowatt hours (kWh) of ultra-clean and renewable electricity produced by
Direct FuelCell^® (DFC)^® power plants since the first commercial installation
in 2003.

"This is a noteworthy achievement highlighting the growing installed base of
our clean and efficient power generation solutions that provide continuous
power to the electric grid or on-site for large power users that value
enhanced energy security and power reliability," said Chip Bottone, President
& Chief Executive Officer, FuelCell Energy, Inc.

Two billion kWh of electricity is adequate to power more than 181,000 average
size U.S. homes for one year.With more than 110 DFC plants producing
environmentally friendly power and usable high quality heat at more than 50
locations globally, DFC plants are eliminating the emission of a significant
level of pollutants and substantially reducing carbon emissions compared to
the average U.S. fossil-fuel power plant.

Two billion kWh of ultra-clean fuel cell power production configured in a
combined heat & power mode (CHP) benefits public health and helps FuelCell
Energy customers achieve sustainability goals by virtually eliminating
criteria pollutants including nitrogen oxide (NO[x]) that causes smog, sulfur
dioxide (SO[x]) that contributes to acid rain, and particulate matter (PM^10)
that aggravates asthma.Compared to the average U.S. fossil-fuel power plant,
this level of fuel cell power generation avoided the emission of approximately
16,900 tons of these criteria pollutants as well as approximately 1,068,000
tons of carbon dioxide (CO[2]), a greenhouse gas, which is equivalent to
removing more than 499,000 passenger vehicles from the road.

"We installed our first commercial fuel cell plant in 2003 and announced one
billion kilowatt hours of ultra-clean power production in January 2011, which
is a time span of eight years," continued Mr. Bottone."We generated the
second billion kilowatt hours in just under two years and the next billion is
expected to be generated in less than one year as a 15 megawatt fuel cell park
is nearing completion in Bridgeport, Connecticut and a 59 megawatt fuel cell
park, the world's largest, is nearing completion in South Korea."

Fuel cells electrochemically convert a fuel source into electricity and heat
in a highly efficient process that emits virtually no pollutants due to the
absence of combustion.The stationary fuel cell power plants manufactured by
FuelCell Energy are fuel flexible, capable of operating on clean natural gas,
on-site renewable biogas, or directed biogas.The power plants provide
continuous baseload power and can be sited where the power is used, including
both on-site applications and electric grid support. The combination of
near-zero pollutants, modest land-use needs, and quiet operating nature
facilitates locating the fuel cell power plants in urban locations and even
within occupied buildings.
