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: German researchers successfully used hydrogen plasma to extract and purify nickel from low-grade ores in a single step, potentially reducing the carbon footprint of nickel production by 84% when powered by renewable energy.
📈 One key stat: The hydrogen plasma method could reduce nickel’s carbon footprint by approximately 84% compared to traditional production methods, greatly decreasing environmental impact as global demand doubles by 2040.
💬 One key quote: “For the first time in history, hydrogen plasma has been used in controlled, peer-reviewed settings to create ferronickel from lateritic ores.”
1️⃣ The big picture: German scientists have achieved a breakthrough in metallurgy by using hydrogen plasma to extract and purify nickel from low-grade ores in just one step. The team at Max Planck Institute for Sustainable Materials created the plasma by applying powerful electric currents to hydrogen-argon gas mixtures in an electric arc furnace. This innovative method eliminates multiple high-temperature, chemical-intensive stages typically required in nickel production that emit large amounts of carbon dioxide. The process yields high-quality ferronickel that can go directly into steel production without additional refining, potentially transforming how we produce this critical metal for electric vehicle batteries and renewable energy technologies.
2️⃣ Why is this good news: This breakthrough dramatically reduces the environmental impact of nickel production by eliminating the need for fossil fuels and cutting potential carbon emissions by 84% when powered by renewable energy. The one-step process avoids the use of sulfuric acid and eliminates the 20 tons of CO2 typically released per ton of nickel in traditional methods. The quality of the ferronickel produced (20-40% nickel content) matches industry standards with fewer impurities, making it immediately usable in steel production. As global demand for nickel is projected to double by 2040 for batteries and clean energy technologies, this cleaner production method arrives at a crucial time to address dwindling high-grade ore supplies.
3️⃣ What’s next: Researchers need to solve scaling challenges since the reaction occurs at the interface between plasma arc and molten ore, requiring careful control of material flow. The Max Planck team is already developing a larger-scale reactor to demonstrate commercial viability. Economic feasibility will improve as green hydrogen and renewable electricity become more affordable in the coming years.
