Australian scientists have isolated an enzyme from a soil bacteria called Mycobacterium smegmatis that can use hydrogen from the air to produce energy. The enzyme, dubbed Huc, splits hydrogen molecules to create an electrical circuit in the cell, making it a potential power source for small devices and implants.
Efficient and Resilient Enzyme
According to Rhys Grinter, principal author of the study, Huc is “extraordinarily efficient” and can consume hydrogen below atmospheric levels. It is also resistant to oxygen, providing adaptable and long-term storage that is similar to a battery. The enzyme is capable of generating energy even in extreme environments, making it a valuable resource for powering devices in hard-to-reach areas.
Potential Applications
While scientists have only generated a small amount of charge from a limited supply of the enzyme, the discovery has enormous potential. Researchers suggest that Huc could be used to power small devices such as clocks, LED lights, or even rudimentary computers. However, with further research and funding, the enzyme’s density could be increased, potentially allowing it to power more substantial equipment such as cars.
The discovery is the result of a five-year research project by scientists at Monash University. According to Chris Greening, a microbiology professor at the university and co-author of the study, bacteria can use the trace hydrogen in the air to help them grow and survive, but until now, the mechanism was unknown. The discovery of Huc and its potential applications could revolutionize the way we power small devices and make a significant impact on the development of sustainable energy sources.
