hydrogen is a net energy loser. It takes more energy to create hydrogen than it creates from burning it.

And where does that energy normally come from? It is produced by burning fossil fuels -- the stuff we're trying to get away from -- in processes that use more energy than the extracted hydrogen is likely to produce. That's called a net energy loser, and until someone solves that problem hydrogen power isn't going to go anywhere.
quote -- The bottom line is that - if we create hydrogen from burning fossil fuels, then we actually burn more energy latent in those fossil fuels than we gain from the hydrogen end product. If we create the hydrogen from renewable sources such as wind and solar then hydrogen is no longer viable because of the enormous amount of power generating devices (wind turbines, solar panels etc) required.
