    The polyoxometalate acts as a sink, storing the protons and electrons released when water is split © NPGUK scientists say that they have developed the first widely-useable electrolysis system that splits water and releases hydrogen and oxygen in separate stages. Lee Cronin and Mark Symes from the University of Glasgow used a phosphomolybdate anion buffer to store protons and electrons generated when oxidising water to oxygen. Instead of directly producing hydrogen, as electrolysis normally does, the buffer lets the scientists choose where and when they do the second step. That could aid efforts to store renewable energy as hydrogen fuel...
