A kilogram of hydrogen holds 39.4 kWh of energy, but typically costs around 52.5 kWh of energy to create via current commercial electrolyzers. Australian company Hysata says its new capillary-fed electrolyzer cell slashes that energy cost to 41.5 kWh, smashing efficiency records while also being cheaper to install and run. The company promises green hydrogen at around US$1.50 per kilogram within just a few years.https://newatlas.com/energy/hysata-efficient-hydrogen-electrolysis/ (https://newatlas.com/energy/hysata-efficient-hydrogen-electrolysis/)
