New Catalyst Cuts Hydrogen Production Costs by One-Third
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: A new hydrogen catalyst achieves record-breaking performance while using only one-third of precious metals compared to conventional platinum catalysts, making clean hydrogen production more cost-effective and efficient.
📈 One key stat: The catalyst shows 4.4 times higher performance than platinum catalysts with the same precious metal content, setting a new benchmark in hydrogen evolution reaction efficiency.
💬 One key quote: “The core-shell catalyst, despite being smaller than 2 nanometers, demonstrates remarkable performance and stability. This breakthrough will contribute significantly to the development of nano core-shell device fabrication technology and hydrogen production, bringing us closer to a carbon-neutral future.”
1️⃣ The big picture: Scientists have developed a breakthrough catalyst that makes hydrogen production significantly more efficient and cost-effective. The new catalyst uses ruthenium instead of platinum and requires only one-third of the precious metal content while achieving superior performance. This innovation features a unique core-shell structure at the nanoscale level, optimizing both stability and efficiency. The development addresses one of the main challenges in hydrogen fuel adoption – the high cost and limited efficiency of current catalysts used in water electrolysis for hydrogen production.
2️⃣ Why is this good news: The new catalyst technology brings clean hydrogen energy production closer to widespread commercial viability. Its improved efficiency and reduced precious metal requirements significantly lower production costs, making hydrogen fuel more accessible. The catalyst’s exceptional stability ensures long-term reliability in industrial applications. This advancement supports the global transition to renewable energy sources and helps reduce dependency on fossil fuels, contributing to a more sustainable future.
3️⃣ What’s next: The research team continues to develop and commercialize the core-shell catalyst technology. Dr. Hyun Woo Lim, selected for the government’s Sejong Fellowship Program, leads further research at Seoul National University. The technology shows strong potential for implementation in hydrogen fuel cells for vehicles, eco-friendly transportation systems, and hydrogen power plants.
