• Melbourne's RMIT University researchers have made a breakthrough in green ammonia production.
• The new method uses liquid metal catalysts, requiring 20% less heat and 98% less pressure than the Haber-Bosch process.
• Lead author Karma Zuraiqi confirmed the new method's effectiveness in producing ammonia with less heat and pressure.
• This breakthrough could significantly reduce carbon emissions and promote clean energy, marking a major step in combating climate change.

In a significant stride towards a greener future, researchers from Melbourne's RMIT University have made a breakthrough in the production of ammonia, a colourless gas that plays a crucial role in both agriculture and clean energy. This development, which could drastically reduce carbon emissions and energy consumption associated with ammonia production, marks a pivotal moment in the global effort to combat climate change.

Ammonia has been industrially produced for over a century using the Haber-Bosch process, a method that converts nitrogen to ammonia via a reaction with hydrogen. This process, while effective, is energy-intensive and contributes significantly to global carbon emissions. The production of ammonia alone accounts for over two per cent of global energy consumption and up to two per cent of global carbon emissions.

Revolutionizing Ammonia Production

The new method developed by the Australian researchers, however, promises to be a game-changer. It relies more on liquid metal catalysts for ammonia production and less on the force of pressure. This innovative approach requires 20 per cent less heat and 98 per cent less pressure than the Haber-Bosch process, making it far more energy-efficient and environmentally friendly.

Karma Zuraiqi, the lead author of the study from RMIT's School of Engineering, expressed optimism about the new method. He stated that this greener approach is as effective as the Haber-Bosch process in producing ammonia, despite using significantly less heat and pressure.

The implications of this breakthrough extend beyond the realm of environmental conservation. Ammonia, once produced, is primarily used in fertilisers, playing a vital role in global food production. However, it also has potential applications in clean energy as a carrier to safely transport hydrogen.

Historical Context and Future Implications

This breakthrough is reminiscent of similar historical events where scientific innovation has led to significant environmental benefits. For instance, the development of catalytic converters in the 1970s drastically reduced harmful emissions from vehicles, contributing to improved air quality. Similarly, the invention of energy-efficient LED lighting has significantly reduced electricity consumption worldwide.

The study detailing this new method was published by Melbourne's RMIT University on a Thursday. While the exact date of publication is not provided, the study can likely be found on the RMIT University's website or in a scientific journal. This means that the new method could not only reduce carbon emissions but also support the development and implementation of clean energy solutions.
