With the ongoing UN climate change conference in Paris this week, Sky News have looked into two currently available zero-emission vehicles, one driven by hydrogen and the other by batteries, as alternatives to our tradition fossil fuel driven ones. Whilst racing the two to Paris makes the comparison into an interesting spectacle and allows both their flaws to be exposed, I am not sure this helps build the case and necessity to continue the development of both technologies and ends up detracting from the importance of both.
There is a perception out there that these are both competing technologies and so a lot of time and resources go into showing one is better than the other. Neither of these technologies is the one and only panacea and both of them can add value to the others technology. This is true across every energy application, not just vehicles. For instance, I'd like to see a vehicle that had both a small battery, for energy recovery, and hydrogen, for propulsion.
Sky News has road-tested green-car technologies in an "eco-rally" to the UN's climate change conference in Paris. We compared the best-selling electric vehicle, the Nissan LEAF, against the first hydrogen-powered car, a fuel-cell version of Hyundai's ix35 SUV.
