Swedish Researchers Boost Hydrogen Fuel Production with New Material
Updated June 23, 2025
Researchers at Linköping University in Sweden have achieved a important breakthrough in renewable energy. They have created a novel three-layer material that dramatically enhances the efficiency of producing hydrogen from water, harnessing the power of sunlight.This advancement paves the way for more lasting hydrogen fuel production.
With the European Union set to ban the production of new gasoline and diesel cars by 2035,the need for alternative fuel sources is growing. While electric vehicles are gaining popularity, they aren’t suitable for all transportation needs. Hydrogen presents a promising solution, especially for heavy-duty vehicles, ships, and aircraft.
Jianwu Sun,an associate professor at Linköping University and leader of the study published in the journal of the American Chemical Society,said hydrogen is a strong candidate for clean and renewable energy sources for transport that cannot rely on batteries.
The Linköping team’s research focuses on materials that can efficiently produce hydrogen (H2) from water (H2O) using solar energy. Their previous work highlighted the potential of cubic silicon carbide (3C-SiC) in splitting water into hydrogen and oxygen. This material effectively captures sunlight, converting its energy into the photochemical water-splitting reaction.
The new material builds upon this foundation, incorporating a layer of cubic silicon carbide, a layer of cobalt oxide, and a catalyst. This combination significantly improves the material’s performance.
Sun said the focus of the study was to understand the function of each layer and how it improves the properties of the material. He added that the new material performs eight times better than pure cubic silicon carbide in splitting water into hydrogen.
When sunlight strikes the material, it generates electric charges that split water molecules. A key challenge is preventing thes charges from recombining and neutralizing. The researchers found that the Ni(OH)2/Co3O4/3C-SiC material effectively separates these charges, leading to more efficient water splitting.
Currently, hydrogen is categorized as either “gray” or “green.” Most commercially available hydrogen is “gray,” produced from natural gas, a fossil fuel. This process releases significant amounts of carbon dioxide, contributing to climate change. “Green” hydrogen, on the othre hand, is produced using renewable electricity.
The ultimate goal is to use onyl solar energy to power the photochemical reaction for “green” hydrogen production. While current materials have efficiencies between 1% and 3%, commercialization requires reaching 10%. Achieving this target would lower the cost of “green” hydrogen production compared to current methods that rely on supplementary renewable electricity. Sun estimates that it may take five to 10 years to develop materials that reach the 10% efficiency threshold.
What’s next
The research team will continue to refine the material, aiming to achieve the 10% efficiency target needed for commercial viability of solar-powered green hydrogen production. Further studies will explore optimizing the material’s structure and composition to maximize its performance and durability.
