Fujitsu and Atmonia discover a novel catalyst candidate for clean ammonia synthesis leveraging high-speed quantum chemical calculations

TOKYO, Oct 3, 2023 - (JCN Newswire) - Fujitsu and Atmonia ehf. (hereinafter referred to as Atmonia), an Icelandic start-up company developing a sustainable process for ammonia production, have achieved a milestone in an ongoing joint research initiative to accelerate catalyst development for the clean synthesis of ammonia, an important raw material for the production of fertilizer and eFuel (1). Drawing on Atmonia's knowledge about catalysts and high-speed quantum chemical calculations developed by Fujitsu, the two companies discovered a novel catalyst candidate in May 2023 in which tungsten (W), a relatively inexpensive substitute for precious metals, replaces a part of molybdenum oxide (MoO2). This research was published in the international journal Cell Reports Physical Science as a co-authored paper by Atmonia, Fujitsu, University of Iceland (2) and Tokyo Institute of Technology (3) in September 2023.

Fujitsu and Atmonia initiated joint research in April 2022 to accelerate the search for ammonia synthesis catalysts by using Fujitsu’s simulation acceleration technology and causal discovery technology. The discovery of promising catalyst materials represents an important step toward the practical application of a clean ammonia production method for generating eFuel and fertilizer.

As part of the discovery process, the two companies first designated approximately 2,400 different catalyst combination candidates, and then performed about 18,000 quantum chemical simulations that considered the reaction process at high speed for all of them, collecting simulation data to conduct a comprehensive search for a relatively inexpensive catalyst that can efficiently synthesize ammonia. After that, based on Atmonia's knowledge of the catalyst development so far, selection criterion for determining a promising catalyst candidate was set including factors like whether it preferentially adsorbs nitrogen rather than hydrogen, and whether it has low electrical energy input at the time of synthesis. The catalyst combinations from the simulation data were narrowed down, leading to the discovery of a promising catalyst material candidate that combines non-precious metals by alloying molybdenum oxide as base with tungsten (patent pending).

Moving forward, Fujitsu and Atmonia will work to verify the effectiveness of the new catalyst material candidates through experiments to one day realize their ultimate goal of clean ammonia synthesis. On October 3 2023, Fujitsu will begin to offer the technology it has developed to streamline material discovery through its Fujitsu Kozuchi (code name) - Fujitsu AI Platform, which that allows users to quickly test out advanced AI technologies. Fujitsu Uvance, which aims to realize a sustainable world, aiming to provide this technology as an offering under the Sustainable Manufacturing portfolio, supporting sustainable growth through the coexistence of people and the earth.
