Alkaline water electrolysers have the perception of not being compatible with renewables. This is largely down to the fact that most AWE electrolysers use bare nickel anodes, or anodes activated with catalysts that cannot withstand current following.
When coupled with renewable energy the electrolyser will be required to switch on and off. This takes the load from positive to negative and with standard anodes this results in corrosion and degradation of performance.
Jolt’s anode coating, Sparkfuze H2A, has been shown to greatly improve the durability of the anode – even under reverse current conditions.
