Hysata testing hydrogen electrolyzer tech in real-world setting – pv magazine Internationalhttps://www.pv-magazine.com/2023/08/14/hysata-testing-hydrogen-electrolyzer-tech-in-real-world-setting/Hysata is developing ultra-high efficiency hydrogen electrolyzer technology that eliminates almost all resistance in the electrolysis process and has the potential to significantly shift the economics of green hydrogen production.
“Existing electrolyzers face energy losses from electrical resistance and gaseous bubbles forming on electrodes, reducing the overall efficiency of the system,” Hysata said. “[The technology] has been proven to produce hydrogen with 95% (41.5 kWh/kg) efficiency, well ahead of incumbent technologies that operate with efficiencies close to 75% (52.5 kWh/kg).”
ARENA said the technology has the “potential to reduce the cost of renewable hydrogen production through reduced electricity inputs … The technology also offers lower balance of plant costs, with reduced electrical resistance resulting reduced cooling requirements. If delivered at scale, these reduced input costs will help lower the levelized cost of hydrogen, making renewable hydrogen a commercially viable energy resource.”
