Australian farmers could soon see their fertiliser costs drop 10 per cent through groundbreaking technology developed by homegrown startup PlasmaLeap. 

This innovation promises to put money back in farmers' pockets and revolutionise the global fertiliser industry, potentially reducing its massive carbon footprint.

Australia consumed approximately $4 billion of fertiliser in 2023, with the average farmer spending almost$300,000 a year.

Using PlasmaLeap’s technology, farmers could save up to $30,000annually, possibly saving up to$400 million for Australian farmers each year.

PlasmaLeap's technology marks a significant departure from the century-old Haber-Bosch process, which has been the backbone of fertiliser production since the early 1900s.While incredibly efficient, the Haber-Bosch process relies heavily on fossil fuels and produces significant CO2emissions.

Professor PJ Cullen, co-founder and chief scientist at PlasmaLeap Technologies said the Haber-Bosch process has reached its limit.

“It's incredibly energy-efficient, but it achieves this by using cheap gas and releasing CO2to get the hydrogen. It only works on a largescale, necessitating long-distance transportation," Professor Cullen said.

In contrast, he says PlasmaLeap's technology operates with renewable electricity, air, and water. The company has achieved production rates which make it competitive with the traditional process, reaching 20 kilowatt-hours per kilogram for green ammonia production.

"We've reached a number which makes us competitive. Critically, the company recently achieved its 20kWh/kg and less than 10 kWH/kg nitrates. While the Haber-Bosch process is around 10 kWh/kg for ammonia, our Creating fertiliser and fuel from thin air technology eliminates transportation costs, making us economically viable,” Professor Cullen says. 

This breakthrough could have far-reaching implications beyond just cost savings for farmers.

Fertiliser costs directly impact foodprices.

Recent global events led to stockpiling and a quadrupling of fertiliser prices.

By enabling localised production, PlasmaLeap's technology could significantly enhance the security of food supply. 

Moreover, the environmental benefits could be substantial.

The current global fertiliser production and distribution system is responsible for CO2emissions equivalent to the entire aviation industry. PlasmaLeap's process, using only air, water, and electricity, eliminates CO2from the equation.

"We're not just tweaking the process; we’re fundamentally reimagining it. The way it's currently done makes no sense. We take nitrogen and hydrogen
– ingredients available everywhere
– and concentrate production in a few countries like India, China, andRussia. Then we ship it globally, adding unnecessary CO2emissions," ProfessorCullen adds.

“Without feasible, commercially viable solutions for green Ammonia production, net zero can’t be achieved, “he added.

The key to PlasmaLeap's potential success lies in its economic competitiveness. By eliminating transportation costs, utilising renewable power generation, and accessing carbon credits, the company expects to offer farmers discounts on fertiliser in the region of 10 per cent.

Graham Gall of Dawson River Pastoral Co describes the technology as “paradigm-shifting" for the agricultural sector, offering greater self-reliance and sustainability.

“In Australia, almost all our nitrogen fertilisers are sourced from overseas, leaving us vulnerable to global supply chain disruptions and price fluctuations,” Graham says.

“PlasmaLeap's solution allows us to produce nitrogen on-farm using green energy sources, which is a game-changer,” he says.

“More importantly, it offers the entire agricultural industry a new level of self-reliance and sustainability.”
