Sure, I don't doubt that it would be
possible to produce hydrogen on a commercial scale. However, I'm still fairly sure that it's
more efficient to use tidal/wind/solar to produce electricity, send that through the existing AC grid and charge batteries in cars rather than to produce hydrogen. And efficiency really counts when you need all the energy you can get, and for the least cost.
Here's an article which addresses a different problem of a "hydrogen economy" - i.e. that fuel cells aren't delivering on their promise:

Well, here in the UK, I certainly know a fair few people who still watch TV (both over and under 30). But many of those who watch TV don't watch ads any more because they watch using some form of digital video recorder. And the advertisers are catching on to this trend.
