Researchers produce hydrogen from biosolids

A new method which uses biosolids to produce hydrogen from wastewater has been developed by researchers at RMIT University.

The technology uses a special material derived from biosolids to spark chemical reactions for producing hydrogen from biogas, meaning all materials needed could be sourced on-site at a wastewater treatment plant, without the need for expensive catalysts.

RMIT University’s method also traps the carbon found in biosolids and biogas, which the researchers believe could in future enable a near zero emission wastewater sector.

Lead Researcher and Associate Professor, Kalpit Shah, said, “Our alternative technology offers a sustainable, cost-effective, renewable and efficient approach to hydrogen production.”

“To enable the transition to a circular economy, we need technology that enables us to squeeze the full value from resources that would ordinarily go to waste. Our new technology for making hydrogen relies on waste materials that are essentially in unlimited supply.”

“By harnessing the power of biosolids to produce a fully clean fuel from biogas – while simultaneously preventing greenhouse gas emissions – we can deliver a true environmental and economic win.”
