I've yet to hear of any commercial hydrogen stations built in the U.S. I heard of ambitious plans to make hydrogen stations powered by solar and water sources.
Other than that, the test island off the coast of Japan for Honda's program to make a self contained community of hydrogen using cars with water based power stations is all I've heard of in the effort.
Also this, but nothing has come of it. (GM, powered by something other than gas, go figure)
