Probably not. It's questionable whether we will ever stop using fossil fuels. And if we do, Hydrogen seems like a poor replacement (low energy density, expensive to make, inefficient). The only advantage seems to be that for some uses you can replace some of the existing fossil fuels (eg replacing some natural gas with hydrogen in stoves).
