  Proton Power Systems Unveils the World's First Triple-hybrid Forklift Truck



Proton Power Systems plc (AIM: PPS), a leading designer, developer and producer
of fuel cells and fuel cell-electric hybrid systems for the 'back to base'
market, today announces that it is has unveiled the world's first triple-hybrid
forklift system in Puchheim, near Munich, Germany.  Designed as a '
plug-and-drive' technology by Proton Motor Fuel Cell GmbH ('Proton Motor'), a
wholly owned subsidiary of Proton Power, the triple-hybrid system offers
significant cost and energy savings and works with all battery types and brands
of forklift trucks.

As stated in its results for the year ended 31 December 2006, together with
buses, forklift trucks are a key market segment for the Company and being able
to offer this unique technology represents an important milestone for Proton
Power, putting the Company in an excellent position to move into
commercialisation.

The triple-hybrid system, 'PM Package MH30', combines a fuel cell, a battery and
supercapacitors to form an energy-efficient power system, replacing the standard
battery package for the Class 1 forklift with an 80 V, 700Ah battery.  As all
components are used in their optimal operation range, the system offers over 50%
energy savings compared with diesel engine forklifts and fuel-cell-only systems.
 In addition, an intelligent energy management system controls the power
distribution between the fuel cell, supercapacitors, and battery.  The energy
recovered during braking is stored in the supercapacitors and batteries, which
provide peak power during operations such as acceleration and lifting heavy
loads.  The 10 kW proton exchange membrane (PEM) fuel cell delivers sufficient
energy to allow the forklift to work for an eight-hour shift and also features a
short recharge time where users can refuel hydrogen for a full working shift in
just one minute.

Including the supercapacitors the system can provide over 30 kW of peak power.
Unlike batteries, which have long recharge and discharge times, supercapacitors
can quickly be charged and discharged for sudden spurts of peak demand.  They
also allow the recovery of energy from highly dynamic actions such as braking.
Complementing the supercapacitors, the battery provides energy buffering over
longer peak demand times.

Felix Heidelberg, CEO of Proton Power, said: 'With Proton Power's system, long
battery charging times, expensive charging stations and the associated logistics
are things of the past.  Our triple-hybrid technology offers unbeatable energy
and cost savings and represents the ideal construction of a hybrid power system.
 Along with the launch of our new facility in Puchheim earlier this month, our
newly unveiled triple-hybrid technology marks another essential step in bringing
Proton Power's technology to the commercial market.'

Notes to Editors

Proton Power Systems plc is a developer of fuel cells and fuel cell hybrid
systems for motive and back-up power supply. Proton Power has more than 13 years
of experience in the fuel cell market. Through its wholly owned subsidiary,
Proton Motor Fuel Cell GmbH, the Company has developed and produced a fuel cell
module running on hydrogen and integrated this with an energy storage system to
create a hybrid electric fuel cell system. The system harnesses the excess power
generated by the fuel cell during partial load (such as stop-start operations)
and uses the stored energy in peak demand times. The system thus boasts lower
fuel consumption and more consistent levels of power delivery than conventional
combustion engine or fuel cell-only systems, in addition to producing zero
harmful emissions.

Proton Power's market focus lies in industrial applications where 'back-to-base'
refuelling occurs at the end of each shift or work period, such as in the
materials handling and mass transportation sectors. In these markets, the
commercialization of applications is possible at a very early stage, as they do
not depend on the existence of a ubiquitous hydrogen infrastructure. Through
partnerships with leading OEMs such as Skoda and Linde, Proton Power's
technology is already deployed in city buses and forklift trucks.

Proton Power also targets the upcoming market for marine transportation
applications and provides the hybrid fuel cell propulsion system for Europe's
first fuel-cell powered passenger ferry, which will be operating in Hamburg from
2008.

Proton Power Systems plc was admitted to trading on AIM on 31 October 2006 and
is based in the UK. Its operating subsidiary, Proton Motor Fuel Cell GmbH, is
located in Puchheim, near Munich, Germany.
