It could be, but as far as the time, I'm not about to speculate. Hydrogen has been around for a considerable amount of time already. Yet it can't seem to get its market legs, so to speak, its ability to prove itself beyond small deployment projects. However, there could be a discovery, potentially at a Canadian university, of some better way of getting hydrogen to the marketplace and making it more cost-effective.
Certainly there have been tremendous inroads made by Canadian companies, such as Ballard Power and Hydrogenics, on getting the cost of fuel cells down and getting them to be very cost-competitive. The challenge now becomes putting it all together onto a vehicle such that the vehicle isn't so outrageously priced that it wouldn't be viable for a consumer.
