A New Way To Split Water
To meet future energy needs, scientists would like to find sustainable ways to generate hydrogen for use in fuel cells and to make liquid fuels. As an alternative to other H2 sources, such as processing of biomass and electrolysis of water, scientists are developing a thermal water-splitting method that would use heat from solar arrays and metal oxide catalysts. But the classic thermal approach has required repetitive heating and cooling, which wastes energy.
