A road ahead via lithium-mediated electrochemical nitrogen reduction?

By on October 03, 2022
Realisation of electrochemical nitrogen reduction to ammonia has proven to be a herculean scientific challenge. Recently, a focus on Lithium-mediated synthesis has delivered promising results. Last year a team from Monash University in Australia unveiled their phosphonium “proton shuttle” method, and this year have reported nearly 100% Faradaic efficiency for the reaction (with promising reaction rates). Late last year, a team from the Technical University of Demark (DTU) reported that addition of small amounts of oxygen gas drastically increased Faradaic efficiencies and production rates. The results push electrochemical synthesis R&D ever-closer to elusive benchmarks set for commercial realisation.

Advanced technologies powering green ammonia R&D

By on November 16, 2022
Fujitsu has been working to find innovative solutions within the energy transition that would benefit from the company’s extensive experience in high performance computing (HPC), AI, quantum computation, materials science, molecular dynamics, and nanoscale materials development. Fujitsu has identified green ammonia as a field with technical challenges that could be addressed by the company’s unique capabilities and has partnered with an Icelandic start-up, Atmonia, to leverage HPC and AI technology in advancing electrochemical ammonia synthesis technology. This talk will provide an overview of the role of advanced technologies to speed up green ammonia R&D.

Nitrogen Reduction Reaction at High Current-to-Ammonia Efficiency

By , and on August 25, 2022
Apart from its use in the fertiliser and chemical industries, ammonia is currently attracting our community as a potential carbon-neutral fuel and as an energy carrier for worldwide transportation of renewable sources. To achieve this goal, replacements of the conventional hydrocarbon deposit-based technology for NH3 production require to be a green but inexpensive and scale-flexible technology, namely the only genuine electrochemical lithium-mediated nitrogen reduction reaction (Li-NRR). Reported by many research groups around the world, the process had so far been hampered by poor yield rates and efficiencies. At Monash University, we introduced a compact ionic assembly arranged in the electrode-electrolyte…

AI & High-Performance Computing for ammonia catalyst R&D

By on April 21, 2022
Fujitsu and Iceland-based Atmonia will join forces to accelerate catalyst development for the production of ammonia via electrochemical nitrogen reduction reaction (eNRR). By using artificial intelligence and high-performance computing (HPC) technologies, the researchers can conduct “high-speed quantum chemical calculations” virtually rather than via physical experiments, allowing for greater flexibility & speed.

High-productivity electrosynthesis of ammonia from dinitrogen

By on August 26, 2021
The so-called lithium redox-mediated nitrogen reduction reaction presents the only known process enabling genuine electrochemical conversion of N2 to ammonia. Notwithstanding the rapidly increasing investigative efforts, the commonly reported performances of the Li-mediated N2 electroreduction, viz. yield rate, current-to-ammonia (faradaic) efficiency and durability in operation, still pertain to the domain of academic research rather than practical development. Our most recent work focused on redesigning the key components of the electrolytic N2 reduction cell enabled breakthroughs in all the key metrics of the process. Specifically, we have introduced a stable proton shuttle based on the phosphonium cation that delivers protons to…
