Technology Description:

Green hydrogen, which is produced with renewable energy and electrolysis, can reduce emissions for the ammonia fertilizer, refineries, chemicals, and steel industries that use hydrogen as a feedstock. Existing water electrolysis technologies are expensive due to high materials cost or complex balance-of-plant systems required when using conventional alkaline electrolysis. The ARPA-E IONICS program developed highly conductive, chemically stable anion exchange membranes that are now commercially produced. Origen Hydrogen aims to develop high-performance, platinum-free electrodes to compliment these breakthrough materials for pure-water electrolysis operation. The team will use engineered low-cost, scalable electrodes that are resistant to the most common degradation pathways.
