Korean Scientists Create Platinum-Free Hydrogen System, Slashing Production Costs
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: South Korean scientists have developed a platinum-free hydrogen electrolysis system that significantly reduces production costs by using larger catalyst particles, making clean hydrogen energy more economically viable and accessible worldwide.
📈 One key stat: Catalyst particles larger than 20 nanometers reduced the pinch-off effect in hydrogen production systems, enabling high performance without expensive platinum metals and potentially slashing production costs.
💬 One key quote: “This breakthrough allowed electrons to move more freely between the catalyst and substrate, achieving high performance without platinum.”
1️⃣ The big picture: South Korean scientists have created a revolutionary hydrogen production system that eliminates the need for expensive platinum. Traditional hydrogen electrolysis relies heavily on rare, costly metals like platinum and iridium to accelerate chemical reactions. The KAIST research team identified a fundamental issue called the ‘pinch-off effect’ in electrode interfaces and solved it by adjusting catalyst particle size. This innovation enables high-efficiency hydrogen production without precious metals, addressing one of the major barriers to widespread hydrogen adoption as a clean energy source.
2️⃣ Why is this good news: This technological breakthrough makes hydrogen production more economically viable by eliminating dependency on scarce and expensive metals. The optimized catalyst layer structure maintains strong catalytic activity while improving conductivity, breaking the traditional trade-off between these two critical factors. Lower production costs will accelerate global hydrogen adoption across various industries and transportation sectors. The innovation positions South Korea as a leader in sustainable energy solutions and provides a clear pathway toward realizing a hydrogen economy with minimal environmental impact.
3️⃣ What’s next: The research, published in Energy & Environmental Science, sets the stage for scaling up this technology for commercial applications. Industry partners will likely begin implementing these findings to develop more affordable hydrogen production systems. Global energy policies may shift to incorporate this innovation, potentially accelerating the transition toward clean hydrogen fuel worldwide.
