A group of Australian scientists has just found an enzyme capable of transforming air into energy. The enzyme, called Huc, uses small amounts of hydrogen in the atmosphere to produce an electrical current.

The study, published in the scientific journal Nature , mentions that the research team at Monash University’s Biomedical Discovery Institute in Melbourne produced and studied a hydrogen-consuming enzyme from a common soil bacterium called Mycobacterium smegmatis.

Scientists find enzyme that converts air into electricity

Previous research by the team revealed that many bacteria use hydrogen from the atmosphere as a source of energy in nutrient-poor environments. However, they didn’t know how it was possible until Huc’s discovery. The researchers used advanced microscopy (cryo-EM) to determine the atomic structure and electrical pathways of the enzyme, and electrochemistry to show that the purified enzyme creates electricity from minute concentrations of hydrogen.
