A Hydrogen Roadblock Cleared?

One of the biggest roadblocks to the development of a practical fuel cell car has been the problem of how to store enough hydrogen to make it practical. Now, a storage technology developed by The University of Queensland may provide the answer to this problem.

The Queensland engineers have developed magnesium alloys that absorb hydrogen like a sponge, store it safely for long periods and release it on demand when either the pressure or temperature is varied. Under laboratory conditions, it can store enough hydrogen to allow a vehicle (carrying a 100kg storage unit) to drive 500 kilometres, which meets a target set by the US Department of Energy for hydrogen storage systems by 2010.If this storage capacity can be achieved in a full-scale prototype at acceptable hydrogen release temperatures.

UniQuest Managing Director, David Henderson said that the scale-up of Hydrexia’s promising technology could deliver substantial reductions in cost and weight when compared to existing hydrogen storage systems. If this storage capacity can be achieved in a full-scale prototype at acceptable hydrogen release temperatures.

This could be a major breakthrough in fuel cell technology.

If this technology pans out, I think cost would be the last roadblock left (as it is for electricity from solar cells).
I believe Iceland has a head start on the costs of productions for the hydrogen with its large amount of geothermal and hydroelectric power. I wonder how they are coming on their conversion to hydrogen.
