Key US Patent Progress

ITM Power PLC 25 September 2007 For Immediate Release 25 September 2007 ITM Power plc ('ITM' or 'the Company') Key US Patent Progress ITM Power's Fundamental Patent allowed in the USA ITM Power plc (AIM:ITM), the technology and research company focused on the commercialisation of the hydrogen economy, is pleased to announce that it has received a 'notice of allowance' for its fundamental patent application from the US Patent Office. It is expected that the patent will be formally granted in the near future. This is a major stage in, and vindication of, the Company's IP strategy. The patent application covers both the unique crosslinked hydrophilic ionic materials which underpin the electrolyser and fuel cell developments made by the Company in the past several years, together with the novel production process. In combination, these developments have allowed ITM to develop low cost platinum free electrolysers and high power density low cost fuel cells. Jim Heathcote, CEO ITM Power, said: 'This announcement is particularly timely because we believe world-wide patent cover is essential before we ship our first products. We are making excellent progress in constructing and fitting out the Company's new production plant and anticipate its completion by the year end, on time and on budget.'

The Company has developed new materials and processes that dramatically reduce the cost of fuel cells and electrolysers. The patented membrane materials used in the devices have higher performance and are 1% of the cost of the industry standard materials. Electrolysers work by converting water and electricity into hydrogen and oxygen. The hydrogen produced can be used as a replacement for fossil fuels and facilitate zero carbon housing and pollution free motoring. ITM Power was founded in 2000 and floated on the London Stock Exchange's Alternative Investment Market in June 2004.
