Technology Description:

Stoicheia aims to accelerate the discovery of proton exchange membrane electrolyzer (PEM) anode catalysts to reduce or eliminate the rare, expensive iridium oxide (IrOx) that is currently the industry standard. Stoicheia’s novel combinatorial process and Megalibrary platform enables the rapid synthesis and characterization of hundreds of thousands of unique materials in a single experiment. Stoicheia seeks to use this approach to accelerate the discovery of reduced IrOX options. PEMs enable both water and CO2 electrolysis to hydrogen and valuable hydrocarbons, respectively, at net-zero carbon. This enables the decarbonization of hard-to-abate sectors like chemicals, industrial heat, and heavy transportation. Low-cost catalyst alternatives are necessary to approach modest projections for electrolyzer deployment and enable corresponding decarbonization efforts in those sectors.
