Hydrogen can now be made using only electricity and the moisture in the air, scientists have found.

According to a paper published Sept. 6 in the journal Nature Communications, this “green hydrogen” is produced by electrolyzing the humidity in the air, rather than the traditional liquid water, which may allow the provision of hydrogen fuel to dry and remote regions, with minimal environmental impact, especially if using renewable energy. The paper’s authors have been able to electrolyze the air’s water in humidity as low as 4 percent.

“We have developed a so-called “direct air electrolyzer” in short, DAE,” Gang Kevin Li, a senior lecturer in the Department of Chemical Engineering at The University of Melbourne, and co-author of the paper, told Newsweek.
