Green hydrogen producers want to leverage abundant wind and solar power for their low costs, and companies are designing their electrolysers to account for intermittent power. Verdagy, based in Moss Bay, California, manufactures dynamic electrolysis systems based on their innovative cell architecture and novel use of new materials and is rising to that challenge.
Verdagy’s patented, single-cell architecture enables electrolysers to seamlessly pair in real-time with variable energy sources, and provide leading efficiencies to enable the industry’s lowest levelized cost of hydrogen (LCOH).
One challenge that Verdagy faces is the lack of appropriate accelerated lifetime tests (ALTs). Most ALTs have been developed either for steady-state power or for other chemistries. Those template ALTs don’t account for increased degradation due to intermittent power profiles. That’s why Verdagy developed specialized ALTs for dynamic loading and engaged with Pulsenics to incorporate operando EIS to track the impact of the ALT profiles on electrolyser degradation. Pulsenics uses electrochemical impedance spectroscopy (EIS), a non-invasive and non-destructive technique, to study electrochemical degradation while the electrolyser stack is operating.
Today, Pulsenics is proud to announce that the International Journey of Hydrogen Energy has published our co-authored white paper “In-operando impedance spectroscopy study for accelerated lifetime studies of dynamic alkaline water electrolysis under industrial conditions”. We are making it available to industry partners to help advance green hydrogen production worldwide.
Who should read the communication?
- Electrolyser OEMs who want to optimize their product for intermittent power
- Electrolyser OEMs developing novel chemistries
- Hydrogen producers who need more visibility into their production stacks
Our scientists found that in-operando (EIS) can precisely monitor and quantify real-time performance changes and degradation mechanisms in dynamic alkaline water electrolysis (AWE) under industrial conditions, thereby enabling ALTs that actually inform business decision-making.
