A new study out of South Korea suggests that your pee could power tomorrow’s clean energy boom. Researchers at Korea Maritime & Ocean University have developed a method to produce hydrogen from urine—yes, human urine—using a small, electricity-free device and a light-powered catalyst.

Why urine? Turns out it's rich in urea, which breaks down more easily than water molecules during hydrogen production. This breakthrough could pave the way for ultra-low-cost, decentralized hydrogen generation—especially in remote or off-grid areas.

The research team envisions portable hydrogen generators that could process wastewater and generate fuel, cutting costs and emissions in one golden stream of innovation. It also sidesteps the energy-intensive process of splitting pure water for hydrogen, making it both greener and cheaper.

💡 So next time nature calls, think of it as a renewable resource.
