A UK green hydrogen start-up has said its alkaline electrolyser technology could offer 89% voltage efficiency with less than 3% degradation.
Oxfordshire-based Electrogenos claims its electrodes matched competitor current densities at less than 1.7V during testing, representing 89% voltage efficiency. While when increased to 1.8V, they achieved densities surpassing 8,000A/m2.
Under accelerated degradation testing, the company says the electrodes showed less than 3% degradation as well as resistance to chromium and iron poisoning.
