New Membrane Cuts Green Hydrogen Energy Use by 30%
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 boron-based membrane material for hydrogen electrolyzers cuts energy use by 30 percent, potentially making green hydrogen cost-competitive with fossil fuel-based production for the first time.
📈 One key stat: Electrolyzers using the new boron-based membranes need only 70 percent of the energy to produce each kilogram of hydrogen compared to existing devices, which could cut operating costs for customers by around 60 percent.
💬 One key quote: “We have a pipeline of potential customers that see around a 60 percent reduction in operating costs with our technology. That’s a nice point of entry,” said 1st Energy co-founder Dan Sobek.
1️⃣ The big picture: Green hydrogen, produced by splitting water molecules using renewable electricity, holds enormous potential as a clean alternative to fossil fuel-based hydrogen production. Right now, most hydrogen comes from high-emissions processes like steam methane reforming and coal gasification. Making green hydrogen truly viable requires it to be cost-competitive, not just clean. Startup 1s1 Energy has developed a boron-based membrane for hydrogen electrolyzers that reduces energy consumption by 30 percent compared to existing devices. By attaching a chemically tailored form of boron onto polymer materials, the company says it has created membranes that are more efficient, more durable, and capable of cutting operating costs for customers by roughly 60 percent.
2️⃣ Why is this good news: A 30 percent reduction in energy use for hydrogen production could make green hydrogen genuinely price-competitive with fossil fuel-based alternatives, removing one of the biggest barriers to scaling clean energy. Beyond hydrogen, the same membrane technology has potential applications in fuel cells, solid-state batteries, and even responsible metal extraction from mining waste, multiplying its positive environmental impact. The boron-based membranes are already meeting the US Department of Energy’s 2031 efficiency target for proton exchange membrane electrolysis, years ahead of schedule. Pilots are already underway with real industrial partners, including a steel company in Brazil, showing the technology is moving well beyond the lab. If widely adopted, cleaner and cheaper hydrogen production could accelerate decarbonization across some of the world’s most emissions-intensive industries.
3️⃣ What’s next: 1s1 Energy is currently running pilots with industrial partners and scaling up membrane production in collaboration with a large materials company. The company is also exploring new applications, including green ammonia production and cleaner extraction of metals like niobium and gold from mines. By 2030, 1s1 aims to have established a solid commercial presence across electrolyzers, mineral extraction, and partnerships with major industrial players.
