Lightning-Inspired Method Creates Cleaner Ammonia From Air, Revolutionizing Fertilizer Production
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Scientists at the University of Sydney have developed a lightning-inspired technique to efficiently produce ammonia directly in its gaseous form from air, potentially reducing the environmental impact of traditional ammonia production.
📈 One key stat: Approximately 90 percent of global ammonia is currently produced using the carbon-intensive Haber-Bosch process, highlighting the environmental significance of this cleaner alternative.
💬 One key quote: “In this research, we’ve successfully developed a method that allows air to be converted to ammonia in its gaseous form using electricity. A huge step toward our goals,” said lead researcher Professor PJ Cullen.
1️⃣ The big picture: Researchers at the University of Sydney have created a breakthrough method to produce ammonia using artificial lightning. This innovative approach creates ammonia directly in its gaseous form, simplifying the production process compared to earlier methods that required additional energy-intensive conversion steps. Ammonia is crucial for global food production, contributing to nearly half of all food grown worldwide through its use in fertilizers. The traditional Haber-Bosch production process generates significant carbon emissions, making this cleaner alternative particularly important for sustainable agriculture and potential green energy applications.
2️⃣ Why is this good news: This new production method harnesses plasma technology to create ammonia without the massive carbon footprint of conventional processes. The technique works by exciting air molecules with electricity and then using a specialized electrolyzer to convert them directly to gaseous ammonia. Since ammonia contains three hydrogen atoms, it shows promise as a hydrogen carrier for clean energy applications and could help reduce emissions in sectors like shipping, which contributes about 3 percent of global greenhouse gases. The process also offers potential for decentralized production, eliminating the need for long-distance transportation of ammonia from large manufacturing facilities.
3️⃣ What’s next: Professor Cullen’s team is now focusing on improving the energy efficiency of their method, particularly the electrolyzer component. They’ve already made the plasma portion viable in terms of efficiency and scalability. The researchers aim to make their approach competitive with the Haber-Bosch process to create a more complete solution for sustainable ammonia production.
