Hydrogen from Thin Air?

Dean Sigler Announcements, Hydrogen Fuel, Sustainable Aviation 1 Comment

Extracting “green” hydrogen from thin air may be a saving grace in attempts to produce clean energy.  Normally, water splitting to produce oxygen and hydrogen requires large amounts of preferably pure water, a rare substance in much of the world. Science News headlines its article, “To overcome the water shortage problem in the case of widespread deployment of hydrogen production, a team of researchers from Australia, the United Kingdom and China has demonstrated a method of producing high purity hydrogen from the air by using hygroscopic electrolyte soaked in a porous medium as the moisture absorbent.” GreenCarCongress notes researchers at [The University of] Melbourne have demonstrated a way to extract hydrogen directly from air via the capture of freshwater using …
