Turning water into hydrogen fuel

The technique converts sunshine and water directly into usable fuel. The technique involves concentrating sunlight in a solar tower to achieve temperatures high enough to drive chemical reactions that split water into its constituent oxygen and hydrogen molecules.
"Our objective is to produce hydrogen (H2) at $2/kg H2,this is equivalent to about US$2/gallon (3.7 L) of gasoline based on mileage in a fuel cell car versus a combustion engine today." With the aid of a solar thermal plant, the team believes that on a land area of about 48,500 ha (120,000 acres) they can generate 100,000 kg (222,460 lb) of hydrogen per day, which is enough to run over 5,000 hydrogen-fuel cell buses daily.
Shame that nobody in the UK has a spare 120,000 acres to cover in solar mirrors.
Perhaps this is good news for our US and Aus friends ?

They don't state if that is Hydrogen gas (at ambient pressure) or compressed or liquid.
Most of the inefficiencies (and cost) come from compressing and if necessary liquifying the hydrogen.
There was a project somewhere that involved a hydro power plant, and then processed the water that had just been dropped through the turbines to create hydrogen (using the power generated). Not sure if it ever got built though.Most of the inefficiencies (and cost) come from compressing and if necessary liquifying the hydrogen.
