Breakthrough: Canadian Scientists Create Hydrogen Fuel Using Only Sunlight and Urea
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: Canadian scientists have developed a groundbreaking method to produce hydrogen fuel using diffuse sunlight, urea, and nanowires, making clean energy production more efficient and cost-effective.
📈 One key stat: The innovative hydrogen production process can function even on cloudy days, thanks to nanowires that capture sunlight from various angles, dramatically improving efficiency compared to traditional methods.
💬 One key quote: “We did it with sunlight and urine,” said researchers from the University of Alberta who split water into hydrogen using urea and weak natural light.
1️⃣ The big picture: Researchers at the University of Alberta have developed an innovative method to produce hydrogen fuel using diffuse sunlight, urea, and nanowires. This breakthrough bypasses traditional energy-intensive electrolysis methods that rely on electricity from solar panels. The new approach employs carbon nitride derived from urea to absorb sunlight and energize electrons, creating electron-hole pairs that facilitate water splitting into hydrogen and oxygen. The technology works even in cloudy conditions and uses abundant, inexpensive materials, making it far more accessible and environmentally friendly than conventional hydrogen production methods.
2️⃣ Why is this good news: This technology eliminates the need for costly silicon solar panels which are environmentally taxing to produce. The materials involved—urea, carbon nitride, and titanium dioxide—are abundant and inexpensive, making large-scale deployment economically viable. The process serves as its own energy storage solution by producing hydrogen gas directly, reducing reliance on bulky batteries. Nations currently dependent on silicon imports can leverage local resources to produce clean energy, enhancing energy independence. The method can potentially be modified to use alternative materials like melamine or even produce hydrogen from methanol, further expanding its applications.
3️⃣ What’s next: The University of Alberta team, led by Karthik Shankar, aims to make this technology commercially viable within three to five years. They’re actively exploring alternative materials and processes to enhance the system’s efficiency and versatility. Their research published in the Journal of the American Chemical Society adds credibility to the breakthrough and its potential impact on the global energy landscape.
