In a bid to raise issues on new and alternate fuel technologies, a pioneering £31 million deal was struck on 3rd April to make hydrogen vehicles a viable and environmentally friendly choice for motorists across Europe. Leading motor manufacturers, hydrogen fuel suppliers, the Mayor of London’s Office and energy consultancies from around the globe have signed up for the HyFive project, the largest of its kind in Europe. Five different manufacturers have agreed to deploy a total of 110 hydrogen fuel cell vehicles at several European locations (Bolzano, Copenhagen, Innsbruck, London, Munich, Stuttgart) and develop new clusters of hydrogen refueling stations. They are expected to be operational by 2015, by which time some of the manufacturers in the partnership will have started to put hydrogen fuelled cars on sale in some European markets. Using hydrogen gas as a fuel to generate electric power the revolutionary vehicles produce no harmful tailpipe emissions – only water vapour. They have the potential to be more than twice as fuel-efficient as conventionally powered vehicles and operate very quietly. The Mayor of London’s Office coordinated the multi million pound project together with BMW, Daimler, Honda, Hyundai, Toyota and hydrogen fuel companies. The motor manufacturers who are part of this project are working on developing and demonstrating hydrogen powered fuel cell cars. The prospect of these becoming more widely available is now seen as increasingly likely as the currently high cost of the technology falls and hydrogen powered vehicles become affordable. Supporters of the new technology point to the rapid re-fuelling times for hydrogen cars and their potential to cover over four hundred miles before needing to be re-fuelled. They also believe that fuel cells will have the ability to be scaled up to run larger vehicles such as buses or trucks.
