Continous operation in flow-cell system

This Science publication is the first ever to prove that the hydrgoen in the synthesized ammonia stems from hydrogen oxidized at the anode. Furthermore, we have found a stable anode catalyst (patent pending), and can run the reaction continously in a flow-based reactor.
This report shows the highest achieved energy efficiency published on the lihtium-mediated system to date.

Rigorous protocol on nitrogen reduction

This Nature publication shows that a high level of rigor needs to be applied in order to successfully produce and measure ammonia. The only conclusive way to prove a successful result is via quantitative isotope labelled experiements using proper gas cleaning procedures.

Herein we screened most of the literature, and found the only reproduceable way to synthesize ammonia: the lithium-mediated nitrogen reduction process.

O2 improves the system

This Science publication a very counter-intuitive discovery, as instead of passivating the metallic lithium, the addition of a tiny bit of oxygen actually enhances the efficiency of the system.

This patent pending addition is ground-breaking for decentralized systems, as it significantly reduces the cost of purifying air, making the systems more cost and energy efficient.

Novel cycling method which enables long-term stability

This E&ES publication presents a novel cycling method, wherein a pulse at high current density is applied to reduce lithium (deposition), followed by a pulse with no current applied (resting), is shown to stabilize the system.

This patent pending method holds the world record for longest continous measurement of the lithium-mediated ammonia synthesis field to date, spanning 5 days with no change in formation rate of the ammonia.

Achieving a record breaking 1,000 mA/cm2

This Joule publication shows the deposition of high surface area porous copper on the working electrode leads to significant increase in the current density, breaking even the DoE target for ammonia synthesis.

This discovery is incredibly important, as high current densities (>300 mA/cm2) are neccessary for commercial application.

Long-term continuous ammonia synthesis

This Nature publication shows the much improved properties of a novel electrolyte formuation for lithium-mediated nitrogen reduction.

This new electrolyte formulation allowed us to continuously operate on the order of weeks. We also produced an astonishing 98% of our ammonia in the gas phase and showed that the use of diglyme as a majority solvent, as opposed to the much more widely used THF, vastly improves electrolyte stability.

Calcium-mediated nitrogen reduction

This Nature Materials publication shows the first ever successul use of a metal other than lithium for metal-mediated ammonia production.

This groundbreaking publication showed that calcium, could serve as a metal mediator for nitrogen reduction. This discovery indicates the potential for less energy-intensive methods of reducing nitrogen to ammonia, crucial for improving nitrolyzer energy efficiency.

Phenol as proton shuttle for ammonia synthesis

This Nature Communications publication shows the highest Faradaic efficiency to ammonia ever achieved in a continuous reactor by utilising a novel electrolyte formulation.

Here, we proved phenol's ability as a novel proton donor to produce ammonia in a continuous flow reactor. Phenol even outperformed the well-established ethanol as an electrolyte additive for lithium-mediated nitrogen reduction.

Advances in metal-mediated ammonia synthesis

This ScienceDirect article presents the current opinion in green and sustainable chemistry, reviewing the advances made in metal-mediated nitrogen reduction towards a commercialisable device.
Here we discuss our journey to Faradaic efficiencies of over 70% and current densities of up to -60 mA cm-2 in a continuous flow reactor. We also propose routes for even further progress towards an optimised commercial device.
