Air can be used for hydrogen production via electrolysis claims study

Air can directly be used for hydrogen production via electrolysis, owing to its universal availability, according to a new study published by Nature Communications.

Air has ‘natural inexhaustibility’ and there are 12.9trn tonnes of water in air at any moment, the study found.

Even in the world’s most challenging environments, such as the Sahel desert and Ayers Rock in Australia, the average relative humidity is about 20% and 21% respectively, the research states.

A solar-driven prototype with five parallel electrolysers has been devised to work in the open air, achieving an average hydrogen generation rate of 745 L H2 day−1 m−2 cathode; and a wind-driven prototype has also been demonstrated for hydrogen (H2) production from the air.
