Giving a 'tandem' boost to solar-powered water splitting

Turning away from fossil fuels is necessary if we are to avert an environmental crisis due to global warming. Both industry and academia have been focusing heavily on hydrogen as a feasible clean alternative. Hydrogen is practically inexhaustible and when used to generate energy, only produces water vapor. However, to realize a truly eco-friendly hydrogen society, we need to be able to mass-produce hydrogen cleanly in the first place.
