Researchers at the Centre for Nano and Soft Matter Sciences (CeNS) in Bengaluru have developed a groundbreaking catalyst that could significantly reduce the cost of producing green hydrogen, a clean energy source. The new catalyst, made from a combination of platinum, palladium, cobalt, nickel, and manganese, promises to make hydrogen production more efficient and affordable, offering potential benefits for both industry and the environment.

A Cost-Effective Solution for Clean Energy

The new catalyst, called a high-entropy alloy (HEA), is designed to improve hydrogen production through water electrolysis. This process splits water into hydrogen and oxygen, but traditional catalysts are often expensive and inefficient. By using a combination of metals in specific ratios, the HEA catalyst reduces reliance on costly materials like platinum, making it a more affordable option for generating green hydrogen, which is considered a key alternative fuel for a cleaner energy future.

Durability and Real-World Benefits

In addition to being cost-effective, the PtPdCoNiMn HEA catalyst has shown exceptional durability. Tests in seawater demonstrated that the catalyst maintained its efficiency for over 100 hours without degrading. This stability makes it a reliable option for large-scale applications, potentially reducing the cost of hydrogen as an energy source for industries, transportation, and electricity generation.
