               Technical Update: Q1 2007 milestone achieved 
 
 
 
 
 
  - Successful assembly of prototype 1kW fuel cell system complete with own 
    control system, gas reformate clean-up and cooling 
 
 
 
  - Prototype testing program well advanced 
 
 
 
  - Voller remains on track for commercialisation of systems by the end of 
    2007 
 
 
 
  - APU system working from widely available fuels such as Calor Gas, propane 
    or LPG and demonstrates quiet operation, low emissions and high efficiency 
 
 
 
 
 
Voller Energy Group PLC, the leading developer of fuel cell systems, is pleased 
to announce that the Company has achieved another milestone towards the 
commercialisation of their 1kW class auxiliary power units (APUs) running from 
standard Calor Gas, propane or liquefied petroleum gas (LPG). Voller engineers 
have now successfully assembled and demonstrated the operation of a complete and 
totally self-contained prototype fuel cell system including a proprietary fully 
automated control and safety system, gas reformate clean-up and cooling. 
 
 
 
This new work takes the development announced on the 28th November one step 
further and demonstrates a completely self contained system working fully 
automatically. 
 
 
 
This development is a significant step forward for the fuel cell industry as the 
Voller APU will run from standard fuels. Most other fuel cell systems require 
pure hydrogen, which is only available from specialist gas suppliers.  Hydrogen 
also has a low energy density which means that a car traveling 100 miles on a 
tank of diesel would travel just 4 miles on an equivalent volume tank of 
hydrogen at 200 bar pressure. 
 
 
 
By contrast, LPG and propane are commonly available worldwide. Calor Gas is 
available from 10,000 outlets in the UK. 
 
 
 
Recognising the realities of the marketplace, Voller has concentrated its 
developments on fuel cell technology, which uses as its base commonly available 
fuel products such as LPG. These products have a high energy density, but when 
used in a fuel cell produce much lower emissions than a conventional generator. 
In developing these products Voller assists the transition from today's high 
carbon economy to a low carbon economy, using high efficiency fuel cell systems 
as an important step along the path to the ultimate solution of the future zero 
carbon economy. 
 
 
 
Stephen Voller, Chief Executive said: 
 
 
 
"Fuel cells are an important technology for the future. The next vital step is 
to commercialise these systems and for users to experience fuel cells 
themselves.  I am proud that Voller Energy is going to be one of the first 
companies in the world to bring products like these to market".
