Scientists from Kiel University have developed an innovative sponge-like material that can obtain drinkable water directly from the humidity in the air. With global temperatures rising and the threat of drought growing steadily, this technology holds the potential to offer a sustainable solution for semi-arid regions facing water scarcity.
The developed composition, named CAU-10-H, was produced using metal-organic frameworks (MOF) to have a highly porous structure. The material's biggest advantage is its ability to retain moisture from the air even at room temperature and a relative humidity of 18%, and release this water through a 60-degree heating process.
In laboratory tests, it was confirmed that each gram of the material can absorb 0.17 grams of water, and one kilogram of the material can produce 1.7 litres of clean water daily. Scientists scaled the production up to an industrial level, reaching up to 30 kilograms, and reduced the material's cost per kilogram to between 10.50 and 12.20 euros, proving the technology's suitability for commercial use.
