here: Honda Sets Up Compact Hydrogen Station in Japan
Honda Motor Co Ltd and Iwatani Corp developed the "Smart Hydrogen Station," the world's first hydrogen station unit containing hydrogen production equipment, hydrogen charging system, etc...

...The installation cost of existing hydrogen stations is reportedly about ¥400 to 500 million (approx US$3.68-4.6 million) per unit, but Honda aims to reduce it by 90%. Honda and Iwatani consider that the new unit will contribute to the spread of hydrogen stations. Honda, which plans to release a fuel-cell vehicle (FCV) in 2015, intends to use the unit for the establishment of basic infrastructure for FCVs...
...The Smart Hydrogen Station developed by the two companies uses utility power to electrically decompose water and produce hydrogen. It can also use renewable energy such as solar electricity for hydrogen production. The government of Saitama City installed the unit on the property of a waste incineration plant and uses electricity generated from exhaust heat produced by incinerating garbage for water decomposition...

And so does Mike Strizki
Scientific American : Inside the Solar-Hydrogen House: No More Power Bills--Ever
A New Jersey resident generates and stores all the power he needs with solar panels and hydrogen
EAST AMWELL, N.J.Mike Strizki has not paid an electric, oil or gas billnor has he spent a nickel to fill up his Mercury Sablein nearly two years. Instead, the 51-year-old civil engineer makes all the fuel he needs using a system he built in the capacious garage of his home, which employs photovoltaic (PV) panels to turn sunlight into electricity that is harnessed in turn to extract hydrogen from tap water...
