Notes to the Editors:

ITM Power is a developer of low-cost hydrogen technologies. 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 domestic 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.
