Retrofitting existing diesel trucks for electrification is a costly exercise. New Aussie start-up has an approach which reportedly enables 4 minute battery swap-outs, is interchangeable with any battery tech, can last 400 - 600 kms, be installed for roughly the same cost as rebuilding/upgrading the existing diesel engine but delivers a 60% reduction in operating costs.
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
