A research team led by Dr. Ryi Shin-kun of the High Temperature Energy Conversion Laboratory of Korea Institute of Energy Research (KIER) successfully in developed a Highly selective Pd composite membrane on porous metal support for high-purity hydrogen production through effective ammonia decomposition.

The low-temperature catalyst-separator complex ammonia reforming technology is a technology that can produce green hydrogen from ammonia using a palladium separator reactor at a low temperature below 500°C.

The ammonia decomposition test test showed that the membrane reactor was able to achieve a high ammonia conversion (99.6 %) and a high hydrogen purity (99.99 %) with a hydrogen production rate of 0.25 Nm3h-1 at 745 K and a gauge pressure of 500 kPa.

The findings of the research were published in ENERGY, a prestigious academic journal.
