Hydrogen is once again in the limelight and with rising fuel prices, the search for fuels beyond petrol and diesel is being debated even more hotly. The European fuel cell bus trial has been extended by one year and there has been much talk about the potential for hydrogen powered vehicles working during the London Olympics. These would bring even more people into contact with future fuels on perhaps boats and buses. The DfT has also announced and major call for more research on hydrogen, clearly indicating a focus on both vehicles and infrastructure. So what is all the hype about this fuel and what does it mean for transport engineers in general? This article tries to address some of those issues by trying to understand hydrogen, and then by looking at how the Icelanders have used this remarkable fuel. There may be some meaningful lessons for the UK and other countries interested in implementing hydrogen. (Author/publisher).
