Decoupling hydrogen production from the need for a water supply could allow green hydrogen to be produced more or less anywhere you can ship it out from \u2013 and since water scarcity and solar potential often go hand in hand, this could prove a boon for much of Africa, Asia, India and the Middle East, too.<\/p>\n<p>Chemical engineers at Melbourne University came up with what they describe as a simple design: an electrolyzer with two flat plates acting as anode and cathode. Sandwiched between the two plates is a porous material \u2013 melamine sponge, for example, or sintered glass foam. This medium is soaked in a hygroscopic ionic solution \u2013 a chemical that can absorb moisture from the air spontaneously.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Australian researchers have developed and tested a way to electrolyze hydrogen straight out of the air, anywhere on Earth, without requiring any other fresh water source.
