For cheaper hydrogen, just add cobalt

Japanese researchers have developed a new water-splitting technology based on a photoelectrochemical system made with titanium dioxide and cobalt. Cobalt is said to be a solid alternative to noble metals such as gold and silver to improve the light-absorbing properties of titanium dioxide used for water oxidation.

New solar water-splitting cell demonstrates 19.3% efficiency, increasing longevity significantly

The cell uses a novel approach that increases its conversion efficiency and longevity at the same time. Researchers claim it is a new world record for this type of application and highlight its importance in storing renewable energy in hydrogen to compensate for output and demand fluctuations.
