Hydrogen, the most common element in the universe, has long been touted as a clean and plentiful alternative energy source. But the easiest way to produce hydrogen fuel requires pure water, which can be hard to get ahold of — and will only become more difficult to source amid worsening droughts around the globe.
Now, in a study published this week in the journal Nature Communicationsscientists have revealed a new way to churn out hydrogen fuel.
What’s new — It turns out that all you need is the humidity that’s naturally hanging in the air, they found, along with their new device that swallows moisture and spits out hydrogen and oxygen. Their method could spur hydrogen fuel production anywhere on the planet.
