Energy transition: South Korea turns plastic waste into clean hydrogen using only sun and water

Researchers from the **Institute for Basic Science (IBS)** in **South Korea** have developed pioneering technology that allows for the **transformation of plastic waste into renewable hydrogen and clean water**, using only **sunlight and water**.

The system, successfully tested for over two months, emerges as a **sustainable and efficient alternative** to traditional methods of energy production.

## How does the floating photocatalytic device work?
The innovation consists of a **one-square-meter floating platform**, equipped with **photocatalytic nanocompounds** suspended on the water surface.
– The system **breaks down dissolved plastics** into useful byproducts such as **ethylene glycol and terephthalic acid**.
– Simultaneously, it releases **pure hydrogen**, without generating polluting emissions or requiring additional chemicals.
– It operates with **tap or seawater**, and **maintains its efficiency even under adverse chemical conditions**.

The catalyst optimizes **gas separation** and prevents unwanted reactions, significantly improving the process performance.

## Environmental advantages and scalability potential
This technology is presented as a **real alternative to methane reforming**, a common but expensive and polluting technique. Among its benefits are:
– **Clean and decentralized hydrogen production**.
– **Utilization of plastic waste**, reducing its environmental impact.
– **High scalability**: simulations indicate that it can be expanded to cover **100 m²**, suitable for **urban and industrial environments**.
– **Operational versatility**, with sustained effectiveness under **prolonged solar exposure**.

## A key tool for the energy future
The development was presented by professors **Kim Dae-Hyeong** and **Hyeon Taeghwan** in the journal *Nature Nanotechnology*, highlighting the system’s potential to **accelerate global energy transition** and contribute to a **circular management of plastic waste**.

## Clean energy from plastic waste and sunlight
This South Korean technology represents a tangible step towards a **decarbonized and waste-free economy**, demonstrating that the **combination of innovation, sustainability, and nanoscience** can generate concrete solutions to the major environmental challenges of our time.
