Roughly the size of a fridge, just as stylish, the household water recycling system is expected to save between 35-45% of average household water use while also reducing energy consumption, carbon footprint & water bills. Sydney Water is trialling it in 30 homes across Sydney.
Currently less available of all the three main electrolyser technologies, solid oxide electrolysers utilise both electricity and high temperature to produce green hydrogen. This unique feature makes it potentially more advantageous for industrial sites seeking to decarbonise. But this Topsoe production site might just help make the units more prevalent!https://globalenergyprize.org/en/2022/09/06/the-worlds-largest-electrolyser-plant/
Scientists in Australia have produced extremely pure (99+%) hydrogen using moisture captured from the air and electrolysis powered by the sun. The technology is known as Direct Air Electrolysis (DAE) and poses a very real promise for water-scare regions.Even more impressive when you think that it can operate in locations with relative humidity levels as low as 4%. As a point of comparison, the average daytime relative humidity at Uluru (Ayers Rock) in the central desert of Australia is (apparently!) 21%.https://www.inkl.com/news/out-of-thin-air-new-solar-powered-invention-creates-hydrogen-fuel-from-the-atmosphere/YjvnXYIqbl
