Researchers have demonstrated a method of producing high purity hydrogen from the air by using hygroscopic electrolyte soaked in a porous medium as the moisture absorbent.
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. Hydrogen is the ultimate clean energy. Despite being the most abundant element in the Universe, hydrogen exists on the earth mainly in compounds like water. The green hydrogen — hydrogen produced by water electrolysis using renewable energy — represents the most promising energy carrier of the low-carbon economy. Hydrogen can also be used as a medium of energy storage for intermittent energies such as solar, wind, and tidal. The deployment of water electrolyzer is geographically…
