        Technical Update: Key Performance and Durability Targets Achieved

Ceres Power, the AIM-quoted fuel cell group, is today providing an update on
the progress achieved in the development of its unique patented fuel cell
technology. Ceres' continued focus is to utilise its technology to deliver a
set of commercially viable products that can be mass manufactured and meet a
clear market need.

Rigorous testing of the fuel cell stacks has demonstrated that the required
levels of durability and performance can be delivered for the market
applications it is targeting, namely domestic combined heat and power (CHP)
boilers, off-grid generators and auxiliary power units (APUs).

* Successful completion to date of more than 7,500 hours of fuel cell stack
testing, reflecting the unique design and the use of well-proven manufacturing

* Testing of more than 50 stacks of up to 1kW power output with repeated thermal
cycling (on/off) between room temperature (20oC) and operating temperature
(600oC) without performance degradation

* Stack testing on a range of commercially available fuels including natural
gas, LPG and propane demonstrating the capability to meet the performance
requirements of a wide range of target market applications

* Validation of stack manufacturing and assembly processes with more than 1,000
stack sub-assemblies constructed with a zero failure rate.

As a result of the performance demonstrated during the testing programme our
core stack technology has been frozen. This technology will be appropriate for
power outputs between 0.5kW and 5kW.

Integrated fuel cell systems have also been demonstrated by coupling
lightweight, compact stacks and fuel processors with other key balance of plant
components for our planned domestic CHP applications. Our focus is now on
completing the designs of end-user products.

As announced at the preliminary results in September, we are currently equipping
a new product facility which is expected to be operational by mid-2007 and is
designed to produce limited volumes of prototype products incorporating volume
manufacturing solutions.  These units will be used both for demonstrations and
larger field trials. The facility will also be used to develop and validate the
manufacturing and assembly processes prior to transfer to mass production.

The scale-up process has been substantially de-risked with the establishment of
a supply chain to procure cell, stack and system components utilising
technologies with well-proven design lives in excess of 10 years. We are already
working closely with a number of OEMs to finalise the arrangements for volume
assembly of products utilising fuel cell stacks that will be manufactured by
Ceres at a 'mother plant' facility planned to be commissioned in mid-2008.

Peter Bance, Chief Executive of Ceres Power, commented:

'Our testing has demonstrated that our unique technology has overcome many of
the obstacles faced by other fuel cell technologies and can deliver  durable,
efficient and cost effective mass market solutions. We are now focused on
completing the design of commercial, compact end-user products.'

About Ceres Power

Ceres is a successful AIM-quoted fuel cell business developing a range of global
market applications including residential combined heat and power, on-site /
back-up generators and auxiliary power units for transport.  Critically,
the technology uses low cost materials and existing mass-production techniques.
And unlike many fuel cells, the Ceres cell can run on widely available fuels
like natural gas, Liquefied Petroleum Gas (LPG) and biofuels as well as on

Since its formation in 2001, the Company has received major recognition for its
technology and business credentials.

Ceres won the prestigious 2003 Carbon Trust Innovation Award for the UK's green
technology with the best commercial potential.

More recently, Ceres secured a top industrial accolade by winning the Institute
of Materials, Minerals and Mining's Gold Medal for 2005.

In January 2006, Ceres Power was selected as the only fuel cell company in the
government's new Energy Research Partnership, contributing directly to national
energy policy.

Ceres Power has raised over #25 million of funding through two rounds of private
equity and its AIM IPO in November 2004.  The company enjoys the support of many
blue chip City institutions as financial backers including Fidelity, Morley and
JP Morgan.

About Ceres Power's Technology

Ceres fuel cell stacks are comprised of multiple fuel cells layered on top of
one another, each made from stainless steel with tiny amounts of ceramic
coating.  The cells combine fuel and air to create electricity and heat via a
quiet, solid state electrochemical process similar to a battery.  As this
process does not involve combustion, unlike an engine or burner, it is highly
efficient and environmentally friendly.

Ceres has developed a unique adaptation of Solid Oxide Fuel Cell (SOFC)
technology, able to operate at temperatures substantially lower than
conventional designs which run at 800 - 1000 degrees C.  By using a new
generation of ceramic materials known as CGO (cerium gadolinium oxide) instead
of the industry standard YSZ (yttria stabilised zirconia), operation at
500 - 600 degrees becomes possible.  This in turn allows use of conventional
stainless steel as the cell substrate, separating the function of mechanical
support from electrochemistry.

The electrochemical layers can then be made extremely thin and optimised for
maximum performance, resulting in industry-leading power density levels, whilst
the stack material costs are radically reduced. The efficiency of converting
fuel into electricity and heat is therefore very high and this efficiency is
maintained across a wide part-load range. In addition, the heat-to-power ratio
is approximately one-to-one making the technology ideal for applications such as
CHP, where levels of electrical output need to be maintained even where heat
demand is modest.

In contrast to totally ceramic cells, these metal-supported cells are
mechanically highly robust and can be easily sealed (e.g. through welding) and
have thermal expansion coefficients well matched to their ceramic coatings.
This allows great resistance to thermal shock, permitting rapid start-up times
and the potential for thousands of ON / OFF cycles for everyday usability.  In
addition, the technology retains the fuel flexibility of SOFC, and has proven
ability to run highly efficiently on commercially available fuels such as
natural gas, LPG and biofuels.

In conjunction with the Ceres stack programme, the Company has been developing
the non fuel cell elements within the complete product, known as the balance of
plant ('BOP'), as part of its systems integration activities aimed at delivering
products for specific customers.  Because of the unique attributes of the
technology, Ceres Power has been able to dramatically reduce the time and cost
of BOP development and systems integration by utilising mature component supply
chains and ordinary, low cost materials. Unlike other fuel cell designs which
operate at more extreme temperatures, time-consuming and expensive bespoke
solutions for BOP components are not required.
