SPLIT UP  Hydrogen, a clean-burning fuel, can be extracted from water molecules by splitting oxygen atoms from the hydrogens. A new computer simulation suggests a strategy for catalyzing that reaction that has the potential to be more efficient than current methods. 

BALTIMORE — For a long time now, hydrogen has been the fuel of the future. A new idea for extracting hydrogen from water might help that future arrive a little sooner.

Today, producing hydrogen requires burning fossil fuels or using water-splitting catalysts that work relatively inefficiently, says physicist Arvin Kakekhani of Yale University. But Kakekhani and Sohrab Ismail-Beigi, also at Yale, identified a strategy using materials known as ferroelectric oxides to catalytically separate hydrogen from oxygen more effectively.
