Cleanly and Efficiently Power a London Office Tower

20 Fenchurch Fuel Cell Installation Supports City of London Low Carbon Zone

DANBURY, Conn., Dec. 4, 2012 (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 that FuelCell Energy Solutions, GmbH has sold a stationary fuel cell
power plant for installation at the 20 Fenchurch office development in London,
England. The ultra-clean and efficient power generation profile of the fuel
cells will facilitate clean air permitting and support London's carbon
reduction targets. FuelCell Energy Solutions (FCES) will manufacture the power
plant.Under a service contract, FCES will also operate and maintain the power
plant from a European-based operations center that is staffed 24 hours a day,
seven days a week.

The 38 story, 690,000 square foot office building is being developed by Canary
Wharf Group, PLC and Land Securities PLC.The building utilizes a distinctive
design that widens as the height increases, providing a smaller footprint and
correspondingly larger public space at street level and additional floor space
for lease on the upper floors.The Direct FuelCell® (DFC®) power plant will
provide electricity and heat in a combined heat and power (CHP) configuration
with high temperature heat provided to an absorption chiller for cooling and
lower temperature heat for facility and hot water heating.The fuel cell will
provide an electrical output of 300 kilowatts (kW), which is adequate to power
almost 800 average sized UK households and thermal output of more than 300 kW.

"The high efficiency of the stationary fuel cell power plant is very important
for this building, from both an economical as well as sustainability
viewpoint," said Paul Mutti Executive Director Canary Wharf Contractors
Ltd."The design and construction of the building incorporates the latest
advances in efficiency and conservation to minimize the building's
environmental impact, including re-use of the demolition material from the
prior building, utilization of solar shading and window glazing that conserves
energy, and the fuel cell power plant that economically generates both
electricity and heat with virtually no emissions."

"The fuel cell power plant is at the heart of the building's sustainability
strategy and will be the first installation of its type in the City of
London's Square Mile," commented Neil Pennell, Head of Sustainability and
Engineering, Land Securities. "Having the opportunity to run the plant on a
day-to-day basis in this landmark building will provide us with a great
insight into the future potential of this technology to reducecarbon
emissions and virtually eliminate the emission of pollutants in commercial
office building applications."

The DFC power plant supports the targets established by the Mayor of London to
supply one quarter of London's energy from decentralized sources and reduce
carbon dioxide (CO[2]) emissions by 60 percent by 2025, supporting the Mayor's
vision for London to be the greenest, big city in the world.Over one year of
power production, the fuel cell power plant will prevent the emission of more
than 40,000 pounds of pollutants including nitrogen oxide (NOx), sulfur
dioxide (SOx) and particulate matter (PM) compared to conventional
combustion-based power generation, which is equivalent to removing 340 cars
from the road.The high efficiency of the fuel cell power generation process
reduces CO[2 ]emissions compared to combustion-based power generation and the
combined heat and power (CHP) configuration further drives efficiency.The
power plant will prevent the emission of 1,800 tons of CO[2] over the course
of one year when compared to conventional combustion-based power generation,
which is equivalent to removing 325 cars from the road.

"This marquee location in central London illustrates the advantages of on-site
fuel cell power generation that efficiently generates power in an
environmentally friendly process," said Chip Bottone, President and Chief
Executive Officer FuelCell Energy, Inc. and Managing Director, FuelCell Energy
Solutions, GmbH. "This power plant is a European solution for providing
ultra-clean distributed power generation as it utilizes European design and
content along with a European based service organization."

FCES, with its German manufacturing base, is the sales, manufacturing and
service business for the European Served Area for FuelCell Energy, Inc.FCES
is a joint venture between Fraunhofer IKTS and FuelCell Energy, Inc.

The DFC300-EU will be installed within the office building as the quiet
operation and virtual lack of pollutants from fuel cells is well-suited for
populated areas. The power generation process of the fuel cell uses an
electrochemical reaction rather than combustion, which very efficiently
converts fuel into clean electricity and heat suitable for generating
steam.Due to the lack of combustion, the fuel cells generate power that is
virtually absent of pollutants.This electrochemical power generation process
is quiet and free of vibrations, allowing for a normal conversational tone
next to an operating fuel cell. 

Generating both electricity and heat from the same unit of fuel reduces fuel
costs and drives efficiency.Fuel cells can achieve up to 90 percent
efficiency when the heat is utilized in a CHP configuration.The heat for this
fuel cell installation will be used for facility heating and cooling,
resulting in maximum fuel efficiency and cost savings with an estimated
overall efficiency above 85 percent.The fuel cell power plant will be
installed in 2013 and commissioned for the building completion in 2014.
