The Honda FCX Clarity achieves more than double the fuel economy of its gasoline equivalent, and one-and-a-half times that of a petrol-electric hybrid, with zero emissions. Huge interest has resulted from Honda making it available 'commercially' to the public in the US, and it is hoped that fuel cell vehicles will rapidly become more widely adopted throughout Europe.

The Grove Fuel Cell Symposium is a major international conference, and provides a European forum to encourage the commercialization of all types of fuel cells, and to promote collaboration in their development and application. The 11th symposium in the series will be held 22–24 September at the Queen Elizabeth II Conference Centre in Westminster, London. The first, held in 1989, commemorated the 150th anniversary of the invention of the fuel cell in 1839 by Sir William Grove.

Grove Medals have been awarded to many world leading figures and organizations developing fuel cells, including Francis (Tom) Bacon for his pioneering development of the fuel cells which were developed into power sources for the Apollo spacecraft. Subsequent winners include UTC, Fuji Electric, FuelCell Energy, the California EPA, Haldor Topsøe, Ballard Power Systems, and Daimler.

The recipients are chosen by the Grove Symposium Steering Committee, and the medals are sponsored by Elsevier, organizer of the event and world-leading publisher of scientific, technical and medical information products and services.

The conference provides a forum for customers and fuel cell developers to discuss their joint aims in this rapidly moving field, while the accompanying exhibition provides a showcase of some of the latest technology.
