Water can be broken down into hydrogen and oxygen with electricity. This facility in Australia will use solar concentrators to directly heat water to 1000 degrees. At this level of heat a given amount of electricity can produce more than twice as much hydrogen in the electrolysis process. In essence, then, they are making hydrogen from direct solar energy (as opposed to solar electricity) by displacing some of the electricity needed for the electrolysis process.
Direct Solar to Hydrogen Plant Goes Up in Australia Hydrogen Cars and Vehicles: "Solar Systems of Hawthorne in Victoria, Australia is developing the country’s first and perhaps even the world’s first direct solar to hydrogen commercial power plant."
