The future of fertilizer production is undergoing a significant change, driven by innovative technologies and a growing demand for sustainable agricultural practices. A recent breakthrough has dramatically accelerated the growth of green ammonia production, offering a promising pathway to reduce the environmental impact of food production. It’s a development that could reshape how we approach global food security.
Revolutionizing Ammonia Production with AI and Plasma Technology
Researchers have successfully harnessed the power of artificial intelligence to discover a novel catalyst that substantially boosts the efficiency of water electrolysis. This process is fundamental to green ammonia synthesis, were water molecules are split to produce hydrogen, which is than combined with atmospheric nitrogen. “It greatly reduced finding time that would have taken months, while improving the process of producing green ammonia sevenfold-exceeding even our most optimistic expectations,” stated a lead researcher involved in the project.
Ammonia is often produced using an electrolyzer to split water molecules and combine the hydrogen with atmospheric nitrogen. A new catalyst discovered in part through an AI system increases the electrolyzer’s efficiency.

The newly developed alloy is now integrated into an electrode within a lab-built prototype system. This air-water-ammonia module combines a nanosecond-pulsed plasma reactor, an electrochemical cell-enhanced with the new catalyst-and complex process optimization tools. The plasma reactor, playfully nicknamed “lightning in a tube,” utilizes brief, intense electrical bursts to energize air and break apart nitrogen molecules, making them readily available for ammonia formation. Together, the electrochemical cell accelerates the conversion of these nitrogen compounds into ammonia.
“it’s a hybrid process running on renewable electricity that bridges plasma chemistry and electrochemistry that we developed ourselves,” explains a key member of the research team. “Air and water are fed into one end, and green ammonia emerges from the other.”
A Scalable Solution: From Lab to Field
the lab-scale module functions as a self-contained air-to-ammonia factory, conveniently packaged within a standard 6-metre shipping container. Powered by renewable sources like solar or wind energy, a pilot setup has demonstrated the ability to produce between 50 and 100 kilograms of green ammonia daily.This output is sufficient to fertilize approximately 1 to 5 hectares of cropland, depending on the specific crop requirements. “and extra modules can be added like Lego blocks when more capacity is needed,” adds the researcher.
Currently, a pilot module undergoing field testing on a farm is connected to the electrical grid to ensure operational stability, rather then relying solely on intermittent renewable energy. This setup is currently delivering 0.5 kg of nitrogen-based fertilizer per day-enough to support the growth of 500 cucumber plants during a single growing season. Furthermore,a significantly larger system is in the planning stages,backed by the new South Wales state government and commercial partners. This ambitious project aims to produce 90 metric tons of nitrogen-based fertilizer annually, powered by a multi-megawatt solar energy plant.
Discussions are also underway with the Bill Gates Foundation regarding the potential request of this technology to produce fertilizer in sub-Saharan Africa, addressing critical food security challenges in the region. According to the Food and Agriculture Organization of the United Nations (FAO), fertilizer use in Africa is significantly lower than in other regions, hindering crop yields and contributing to food insecurity. (FAO, 2024).
The research team is actively working to commercialize the current system, with a goal of reducing the lab setup to a suitcase-sized device capable of producing a couple of kilograms of ammonia per day at a cost of under AU $1 million (approximately US $655,000 as of August 1, 2025).
Considering the broader landscape, ammonia is already one of the world’s most widely produced chemicals. Existing infrastructure for liquefaction, storage, and transportation is well-established, with operational docking points, pipelines, tanks, and terminals already in place.
“Our containerized modules will empower regions abundant in renewable energy to produce green ammonia in real-time, eliminating the need to wait for the construction of billion-dollar hydrogen plants and supporting infrastructure,” explains the researcher. “This fuel can then be utilized in multiple ways: as fertilizers, converted back into hydrogen for fuel-cell vehicles, or combusted in turbines and engines for clean backup power.”
