Scientists in Japan have created a functioning prototype reactor that can generate hydrogen fuel directly from water using sunlight, according to recent energy research reports. This system uses special photocatalytic sheets that harness solar energy to split water molecules into hydrogen and oxygen without requiring electricity.
The prototype has been operating successfully for three years, demonstrating potential for practical applications. While green hydrogen is considered crucial for a sustainable energy future, current production methods remain expensive and energy-intensive. This breakthrough could significantly reduce costs and simplify production.
