Solar-powered paint could produce hydrogen for fuel

Split a water molecule, and you get hydrogen and oxygen. Burn that hydrogen as fuel and you get water.

Unfortunately, splitting water molecules to generate hydrogen is not currently very energy efficient. In fact, more than 95 percent of hydrogen currently used in industry is produced from fossil fuels, not water.
