Turning Waste into Wonder: Hydrogen from Plastic with Sunlight!
Seoul, Friday, 13 June 2025.
Korean scientists have unveiled tech that turns plastic waste into clean hydrogen using sunlight. This eco-friendly breakthrough offers a two-in-one fix: tackling plastic pollution while producing sustainable energy.
Innovative System for Plastic-to-Hydrogen Conversion
Researchers at Seoul National University’s Institute for Basic Science have developed a photocatalytic system that ingeniously turns plastic waste, specifically PET bottles, into clean hydrogen fuel using sunlight. This eco-friendly advance not only generates valuable hydrogen fuel but also breaks down plastics into useful byproducts, effectively tackling both energy needs and environmental pollution [1].
Floating Photocatalysts with Staying Power
A clever aspect of this technology involves using a hydrogel polymer to wrap the photocatalyst, which allows it to float on water and remain active even in challenging conditions. Interestingly, tests showed the system remained stable for over two months, working in various water sources such as tap and seawater [1].
Practical and Scalable Solutions
Simulations suggest this technology can be scaled up to cover areas of up to 100 square metres, enhancing its ability to produce hydrogen fuel effectively. This scalability opens doors for cost-effective, carbon-free hydrogen production, positioning it as a formidable player in the renewable energy sector [1].
Real-World Applications and Impact
This development is significant in its practical application. Designed to function in real-world conditions, it represents a stepping stone toward a hydrogen-powered society. By transforming waste into a valuable energy source, it reflects the dual benefits of reducing environmental pollution while meeting the energy sector’s demands [1][3].
Expert Perspectives and Future Vision
According to Dae-Hyeong Kim, a professor at the Institute for Basic Science, this innovation marks a meaningful step toward addressing both environmental and energy challenges. The potential to produce clean energy from plastic waste presents a new path for hydrogen technology’s future [1].
