The Amplifier.
Iridium scarcity is no longer a gating factor for the future of PEM electrolyzers. Calicat’s Amplifier is a durable and performant Iridium replacement for primary Oxygen Evolution Reaction catalysis. By trading a small amount of overpotential for high durability and lower CapEx, Amplifier delivers lower LCOH than iridium in the low-capacity-factor electrolyzer installations that are becoming more common in the new reality of Production Tax Credits from the Inflation Reduction Act.

Boosting Efficiency Sustainably
Unlike iridium, amplifier doesn’t dissolve at high CDs.
Amplifier is designed to thrive at high Current Densities.
Current Density is the greatest tool the electrolyzer industry has for amortizing CapEx to reduce the LCOH. This is increasingly true in the low capacity factor environments for which Amplifier was designed. Iridium has demonstrated dissolution due to interaction with unavoidable reaction intermediates – an intractable chemistry problem innate to the mineral. Amplifier is stable for thousands of hours, demonstrating no experimentally discernable voltage drift as current density is increased.
Amplifier combats low capacity factor with high current density-sustainably.
Operators of Green Hydrogen generation facilities want to turn on their electrolyzers early, turn them off late, and make the most of the limited peak solar irradiation time each day. Amplifier’s slower dissolution enables operational flexibility that increases the dynamic range of the system, “over-driving” to higher current densities without hastening expensive stack replacement. This enablement beats traditional “over-sizing” approaches on a levelized cost basis.
