Sustainable ammonia synthesis: SUNCAT’s lithium-cycling strategy

New research coming out of Stanford University suggests a fascinating new direction for electrochemical ammonia synthesis technology development.

The US-Danish team of scientists at SUNCAT, tasked with finding new catalysts for electrochemical ammonia production, saw that 'selectivity' posed a tremendous challenge - in other words, most of the energy used by renewable ammonia production systems went into making hydrogen instead of making ammonia.

The new SUNCAT solution does not overcome this selectivity challenge. It doesn't even try. Instead, these researchers have avoided the problem completely.

Electrochemical ammonia synthesis in South Korea

One of the many encouraging announcements at the recent Power-to-Ammonia conference in Rotterdam was the news that the Korea Institute of Energy Research (KIER) has extended funding for its electrochemical ammonia synthesis research program by another three years, pushing the project forward through 2019.

KIER's research target for 2019 is significant: to demonstrate an ammonia production rate of 1x10-7 mol/s·cm2.

If the KIER team can hit this target, not only would it be ten thousand times better than their 2012 results but, according to the numbers I'll provide below, it would be the closest an electrochemical ammonia synthesis technology has come to being commercially competitive.

On the Ground in Germany

Yet another national laboratory is developing technology for renewable ammonia, this time in Germany at the DLR, the German Aerospace Center.

At the Institute of Thermodynamic Engineering, the DLR is developing a method for electrochemical ammonia synthesis at ambient conditions.
