Out of thin air: new solar-powered invention creates hydrogen fuel from the atmosphere

Well that’s a game changer.


Researchers have created a solar-powered device that produces hydrogen fuel directly from moisture in the air.

According to its inventors, the prototype produces hydrogen with greater than 99% purity and can work in air that is as dry as 4% relative humidity. The device would allow hydrogen to be produced without carbon emissions even in regions where water on land is scarce, they say.

MIT’s MOXIE experiment reliably produces oxygen on Mars

“It’s historic,” says MIT scientists.

In a significant breakthrough, the Massachusetts Institute of Technology’s (MIT) lunchbox-sized machine has been producing oxygen from the Red Planet’s atmosphere for more than a year, giving hope of life on Mars one day.

Since April 2021, the MIT-led Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) successfully made oxygen from the Red Planet’s carbon-dioxide-rich atmosphere, according to a press release published by the institute on Wednesday.

“It’s historic,” said MOXIE’s deputy principal investigator Jeffrey Hoffman, a professor of the practice in MIT’s Department of Aeronautics and Astronautics.


MIT’s MOXIE experiment has now produced oxygen on Mars. It is the first demonstration of in-situ resource utilization on the Red Planet, and a key step in the goal of sending humans on a Martian mission.
